BioInterfaces

Engineered nanoparticles and interfaces for modulation and monitoring of biological systems.

Team leader BioInterfaces: Prof. Dr. Oya Tagit

Nanoparticles precisely engineered at the nanoscale have emerged as novel therapeutic and diagnostic agents due to their unique physicochemical properties (e.g. optical, magnetic, electronic, etc.) that are dictated by their size, shape, composition, surface; and can be customized for the desired biological targets and functions. With applications ranging from imaging and detection probes to nanocarriers for (bio)therapeutics delivery, engineered nanoparticles can give unprecedented information on the chemical and physical processes that take place in biological systems, and enable targeted therapeutic interventions.
In the group of BioInterfaces, we aim to address currently unmet biomedical needs in the diagnosis, monitoring, and treatment of disease with engineered nanoparticles tailored for the desired biological targets and functions. We utilize an interdisciplinary approach at the interface between materials chemistry, nanotechnology, and biology for bench-to-bedside development of optical and magnetic detection probes, (pre-)clinical imaging agents, and drug delivery systems based on inorganic and polymeric nanoparticles. We study the diagnostic and therapeutic performance of these nanoparticles in vitro and in vivo using advanced imaging and cell culture techniques and disease models.

Novel biocompatible and biodegradable polymers for biomedical applications

We design novel bio-based polymers to develop biocompatible and biodegradable nanocarriers as alternatives to e.g. PEG.

Multi-compartment nanofactories for on-site and on demand drug synthesis and delivery

We develop compartmentalized vesicles with internal compartments that can be triggered independently and selectively to release their cargo. Libraries of novel stimuli-responsive block co-polymers are prepared for vesicle formation, and release is actuated by external stimulus such as light, magnetic field, etc.

Nanocarriers for mRNA therapeutics

Combining the stability of polymers with transfection efficiency of lipids, we developed polymer-lipid hybrid nanoparticles, which can be stored as lyophilized powder and display long-term storage stability also in suspension. Lyophilization does not impair transfection efficiency.

Nanomedicine and theranostics

Diverse nanoparticle formulations based on polymers, lipids, and combinations thereof, loaded with (bio)therapeutics such as antimicrobial peptides, small molecule drugs, and nucleic acids are developed to combat infectious diseases and cancer. We further develop inorganic nanoparticles (metal and semiconductor) and drug-conjugated luminescent probes with cleavable linkers for simultaneous therapy and…

Tailor-made nanoparticles

Using top-down and bottom-up synthesis, encapsulation, surface engineering, and bioconjugation approaches, we develop nanoparticles with precisely defined and controlled size, morphology, composition, and surface functionality, and tailor them for the desired biological targets and functions.
