Peters, J.A. (author), Djanashvili, K. (author)In this review, the chemical mechanisms behind the interactions between boronic acids and N-acetylneuraminic acids, which have been widely utilized in biomedicine in recent decades, will be examined. It will also be highlighted that the affinity of boronic acids for N-acetylneuraminic acids is dependent on pH and is complementary to their...review 2023

Piergentili, I. (author), Cai, Mao (author), Klemm, B. (author), Xu, B. (author), Luo, Sanzhong (author), Eelkema, R. (author)The redox balance in tumor and diseased cells often leads to the production of reactive oxygen species (ROS). Many ROS-responsive materials based on sulfur oxidation have been reported with the goal of achieving controlled delivery at the tumor. However, these materials often lack responsiveness to low ROS concentrations present in the tumor...journal article 2023

(author), Stæger, Frederik Filip (author), Sigurdsson, Björn (author), Rosenholm, Marko (author), Beekman, F.J. (author), Jensen, Andreas I. (author)Nanoparticles are ultrafine particulate matter having considerable potential for treatment of central nervous system (CNS) disorders. Despite their tiny size, the blood-brain barrier (BBB) restricts their access to the CNS. Their direct cerebrospinal fluid (CSF) administration bypasses the BBB endothelium, but still fails to give adequate...journal article 2023

Kerssemakers, Tom (author)With over 75,000 attributed deaths in 2020, opioid overdose is now the leading cause of death amongst Americans under the age of 50. With record-breaking increases in fatalities for the past 10 years, fentanyl in particular has many experts worried about the future of the opioid epidemic. To reverse opioid overdose there exists a drug called...master thesis 2022

(author), Bodaghi, Mahdi (author)Magneto-/ electro-responsive polymers (MERPs) are a class of stimuli-responsive materials that are actuated when triggered by external magnetic/ electric fields. MERPs exhibit rapid, reversible, and safe multi-functional and dynamic (i.e., changing with time) properties, which can effectively be manipulated at different length scales. These...review 2022

(author), Verweij, M.D. (author), Kooiman, Klazina (author)Ultrasound insonification of microbubbles can locally enhance drug delivery by increasing the cell membrane permeability. To aid development of a safe and effective therapeutic microbubble, more insight into the microbubble-cell interaction is needed. In this in vitro study we aimed to investigate the initial 3D morphology of the endothelial...journal article 2022

La Zara, D. (author)The majority of pharmaceutical products is made of solid powders. The morphology and surface characteristics of drug particles affect both their bulk behaviour, e.g., flowability, dispersibility and tabletability, in the manufacturing process of dosage forms as well as their bioavailability upon administration into the human body. For instance,...doctoral thesis 2021

Bouwmans, Pepijn (author)Treatment of cancer requires local medication at the tumor site to prevent side-effects of chemotherapy. Nanocarriers, such as micelles, can be used to transport drugs to the tumor site and limit side effects of cancer treatment. Micelles are easy to produce, have a high solubilization potential for hydrophobic drugs and therefore can have high...master thesis 2021

(author), Deckers, Roel (author)Chemotherapy efficacy is often reduced by insufficient drug uptake in tumor cells. The combination of ultrasound and microbubbles (USMB) has been shown to improve drug delivery and to enhance the efficacy of several drugs in vitro and in vivo, through effects collectively known as sonopermeation. However, clinical translation of USMB therapy...journal article 2021
