On-body biodesign
exploring the human body’s role in designing with living organisms
On-body biodesign involves designing with living organisms in direct relation to human bodies and their surrounding ecosystems. Operating within this intimate and dynamic space, the practice creates opportunities by developing novel biotechnologies, cultivating new sensibilities, strengthening ecological literacy and enabling more attentive and reciprocal coexistence with other living organisms. Yet, given the emerging and cross-disciplinary nature of the field, existing work remains fragmented. How are designers currently biodesigning with, for and through human bodies, and what design opportunities could emerge for future on-body biodesign? To address these questions, we present a review of 40 artefacts spanning design, art, HCI and materials science, mapping the design space across three dimensions: the key biological phenomena that enable interactions, the unique experiences these interactions offer and the ecological configurations through which human bodies, living organisms and digital technologies interface with one another. With this work, we aim to introduce on-body biodesign as a design research programme and offer a structured overview of its current landscape. We further outline potential design pathways, inviting designers to engage with on-body biodesign as a generative space for relational thinking and regenerative practice.

By leveraging the unique qualities of microorganisms, engineered living materials (ELMs) offer functional and economic advantages in everyday applications along with notable ecological benefits. This study contributes to the growing field of biodesign by examining the potential of Flavobacteria for thermochromic ELMs. Many Flavobacteria, commonly found in marine environments, produce iridescent structural colorations as their colonies expand on semi-solid surfaces through gliding motility. In this study, we analyzed the effects of temperature variations on flavobacterium Cellulophaga lytica PLY-A2, characterizing distinct changes in colony growth and iridescent colorations at a macroscopic and microscopic scale. Using scanning electron microscopy, we investigated the relationship between iridescent color and the underlying cell-based optical structures. By providing insights into the temperature-responsive behavior of Flavobacteria, our findings highlight their potential for future thermochromic ELMs—with applications ranging from sustainable food packaging to smart textiles—while encouraging further characterization studies within biodesign research.

Seasonal biodesign
Real-world studies with living artefacts for urban biodiversity
Living artefacts situated in real-world contexts hold potential to support regenerative ecologies, for instance by enabling multispecies interactions and promoting biodiversity. However, a gap between theory and practice remains in demonstrating this potential, partly due to absent methodological frameworks that enable biodesigners to systematically engage with ecosystems and the unpredictable biotic and abiotic factors they entail. In response, we present an approach that integrates field studies and laboratory experiments, demonstrated through studies across four seasons in which living artefacts were situated in urban garden contexts. By harnessing the habitabilities of bacterial cellulose, these artefacts were designed to attract, host and surface local biodiversity. Through photography and deoxyribonucleic acid (DNA) analysis, the study reveals a rich diversity of multispecies interactions, varying across artefacts, gardens and seasons. Our findings highlight prospects for biodesigners to thoughtfully tune ecological habitabilities and interactions through living artefacts and offer guidance on navigating tensions between intentionality and openness.

Bacterial cellulose (BC), also known as a Kombucha mat or SCOBY, is a grown material widely adopted in design and HCI communities due to its biodegradability, accessibility and mechanical versatility. Alongside these aspects, BC's qualities to become a habitat for other living organisms, i.e., its habitabilities, have been researched in biotechnological sciences but not fully explored in design. In response to the call for biobased material alternatives and the expanding design space for multispecies interactions in HCI, in this paper, we unpack this habitability potential of BC in the design of living artefacts. Through visual storytelling we unveil our hands-on biolab journey with Komagataeibacter, the bacteria that produce BC, and show how fungi, microalgae and cyanobacteria can inhabit this material. We outline diverse options for tuning the habitabilities of BC to incite HCI designers in the creation of living artefacts that are fully grown and compatible with regenerative ecologies.

A reflective lab journal for biodesign
Navigating more-than-human sensibilities and disciplinary tensions
This paper introduces reflective journaling as a tool for advancing biodesign practices, merging documentation methods from biology and design while integrating more-than-human sensibilities into laboratory practices. It highlights the need for tools that can flexibly support record-keeping across biology and design, balancing precision and accountability with iteration, creativity, and collaboration. Furthermore, it critically addresses calls to support care ethics and nurturing multispecies interactions within biodesign. Through an explorative review of diverse documentation formats, including laboratory notebooks and annotated portfolios, and informed by our own biodesign experiences, we introduce the Reflective Biodesign Lab Journal as a potential approach to address these needs. This innovative format is designed to support rigorous experimentation, creative design processes, and interdisciplinary reflections. This proposal lays the groundwork for addressing the unique nature of biodesign experiments, unlocking new possibilities that transcend the limitations of traditional disciplinary approaches.

Becoming microbes
An approach to cultivating microbial sensibilities in biodesign
Microbes assume an indispensable role in design, given their inherent adaptability, functional diversity, and abundance. Yet, designing with microbes presents notable challenges for biodesigners, stemming from, for example, the distinct temporalities and scales of microbes. Conversely, cultivating microbial sensibilities—reflecting human comprehension and alignment with the distinctive characteristics of microbes—stands out as a unique potential of biodesign for fostering a deep connection between humans and other living entities. In response, we present the concept of “becoming microbes”, a philosophically grounded approach advocating for a non-anthropocentric stance in biodesign, aiming at immersing biodesigners in the realms of microbes with a fresh perspective for imagining the world through the lens of a microbe. By harnessing diverse microbial qualities, including motility and communication, we present various design avenues to explore the notion of becoming microbes. We reflect on the role of merging the biological with the immersive digital systems in this context.

(Re)activate, (Re)direct, (Re)arrange
Exploring the Design Space of Direct Interactions with Flavobacteria
HCI designers increasingly engage in the integration of microbes into artefacts, leveraging their distinct biological affordances for novel interactions. While in many explorations the interaction between humans and microbes is mediated, scholars also highlight the potential of direct interactions, such as visualising mechanical distortions or fostering a sense of relationality with nonhumans through eliciting intimate encounters. Seizing upon this potential, our study delves into the realm of direct interactions involving Flavobacteria, recently introduced as a colour-changing interactive medium in HCI. We present a design space for direct interactions where humans can (re)activate, (re)direct, and (re)arrange Flavobacteria’s colourations, thereby fostering a personal and dynamic interplay between humans and microbes. With our work, we aspire to provide pathways and ignite inspiration among HCI designers to create living artefacts that cultivate active engagement and heightened attentiveness towards microbial worlds and beyond.

Microbes offer designers opportunities to endow artefacts with environmental sensing and adapting abilities, and unique expressions. However, microbe-embedded artefacts present a challenge of temporal dissonance, reflected by a “time lag” typically experienced by humans in noticing the gradual and minute shifts in microbial metabolism. This could compromise fluency of interactions and may hinder timely noticing and attending to microbes in living artefacts. In addressing this challenge, we introduce Cyano-chromic Interface, in which photosynthetic activity of cyanobacteria (Synechocystis sp. PCC6803) is timely surfaced by an electrochromic (EC) material through its monochromatic display. Grounded through interface performance characterization and design primitives, we developed application concepts through which we instantiate how the interface can be tuned for diverse functional and experiential outcomes in living artefacts. We further discuss the potential of aligning human-microbe temporalities for enriched interactions and reciprocal relationships with microbes, and beyond.

The Nagoya Protocol on Access to Genetic Resources and Fair and Equitable Sharing of Benefits Arising from their Utilization came into force in October 2014. In the European Union (EU), new legislation had to be developed in order to apply the mandatory elements of the Protocol, namely, the Regulation (EU) N° 511/2014 (ABS Regulation) and the Implementing Regulation (EU) 2015/1866, laying down detailed rules for the implementation of Regulation ABS with regard to the register of collection, monitor user compliance, and best practices. As a consequence, EU countries had to develop their own legislation in order to implement the Nagoya Protocol (NP), as well as the EU regulations. One important fact that distinguishes the national legislation of the EU countries is that some countries choose to control access to genetic resources (GR), while others do not apply access measures. The Atlantic Area countries in the EU share an attractive coastline with regard to the potential of their GR. In addition, the microalgae industry has been identified as a business sector with high potential. Therefore, it is important for GR users to be informed about the existing regulations and the national differences that may occur within EU countries. In this article, the origins and main content of the Nagoya Protocol are described, together with their implications at the EU level and particularly in the countries of the Atlantic Area region. As a result, a decision framework is proposed in order to support the GR users among this region.

Cyanobactins are a recently recognized group of ribosomal cyclic peptides produced by cyanobacteria, which have been studied because of their interesting biological activities. Here, we have used a PCR-based approach to detect the N-terminal protease (A) gene from cyanobactin synthetase gene clusters, in a set of diverse cyanobacteria from our culture collection (Laboratory of Ecotoxicology, Genomics and Evolution (LEGE) CC). Homologues of this gene were found in Microcystis and Rivularia strains, and for the first time in Cuspidothrix, Phormidium and Sphaerospermopsis strains. Phylogenetic relationships inferred from available A-gene sequences, including those obtained in this work, revealed two new groups of phylotypes, harboring Phormidium, Sphaerospermopsis and Rivularia LEGE isolates. Thus, this study shows that, using underexplored cyanobacterial strains, it is still possible to expand the known genetic diversity of genes involved in cyanobactin biosynthesis.
