Micro/nanoparticle engineering for medical use

Micro/nanoparticulate systems may provide a few functionalities to bio-actives for medical uses such as drug delivery, tissue engineering and new therapies.

Mechanistic understanding of the formation of the micro/nanoparticles and their impact on bio-environment is essential for rational design of these systems.

The aim of our projects is to study the physical and chemical mechanisms that determine the engineering of aforementioned micro/nanoparticles, the interplay between the particles and bio-membranes or cells, as well as the mechanisms that control the release of the bio-actives from the micro/nanoparticulate systems in vitro and in vivo.

The goal is to engineer micro/nanoparticles or nano-structured composite particles via wet chemistry or atomization technologies including spray-drying, spray freeze-drying and electrospraying/electrospinning for respiratory, per oral or subcutaneous administration of poorly water-soluble drugs, protein/peptide drugs and siRNA, or tissue engineering.

The physical and chemical degradation of the bio-actives upon various processing will also be characterized.
