(author), Manni, Francesca (author), Edström, Erik (author), Terander, Adrian Elmi (author)Background: In brain tumor surgery, maximal tumor resection is typically desired. This is complicated by infiltrative tumor cells which cannot be visually distinguished from healthy brain tissue. Optical methods are an emerging field that can potentially revolutionize brain tumor surgery through intraoperative differentiation between healthy...review 2024

van Zee, Tim (author)Surface-enhanced Raman spectroscopy (SERS) is a powerful non-destructive molecule identification technique. The technique is made viable by the enhancement of the Raman effect which is caused by metallic nanoparticle (MNP) structures. A fabrication method that can manufacture highly consistent SERS substrates is important. Aerosol Direct Write ...master thesis 2023

Komen, I. (author)In this thesis we describe three results of the interaction between WS2 and light: photoluminescence, the formation of exciton-polaritons and Raman scattering. The chirality of the photoluminescence interaction between WS2 and light opens the way for applictions in nanophotonics and specifically valleytronics, the field of interacting with and...doctoral thesis 2021

(author)It is well known that disordered relaxor ferroelectrics exhibit local polar correlations. The origin of localized fields that disrupt long-range polar order for different substitution types, however, is unclear. Currently, it is known that substituents of the same valence as Ti<sup>4+</sup> at the B-site of barium titanate lattice produce...journal article 2021

(author)The heme enzyme chlorite dismutase (Cld) catalyzes O-O bond formation as part of the conversion of the toxic chlorite (ClO2-) to chloride (Cl-) and molecular oxygen (O2). Enzymatic O-O bond formation is rare in nature, and therefore, the reaction mechanism of Cld is of great interest. Microsecond timescale pre-steady-state kinetic experiments...journal article 2021

(author)We realized integrated photonics multi-waveguide devices for optical trapping and Raman spectroscopy of particles in a fluid. In these devices, multiple beams directed towards the device center lead to a local field enhancement around this center and thus counteract the effect of light concentration near the facets, which is a disadvantage of...journal article 2020
