Nanoparticules d'or ultrastables et mucoadhérentes pour l'administration cornéenne de médicament

Nouveau système de relargage de médicaments

Increasing the corneal residence time of drugs is a current challenge in ophthalmology. Drug vectors with such properties can increase the efficiency of drugs, thereby reducing the frequency of administration, the duration of treatment, and the risk of post-surgical infection that may lead to sight loss.

The team of Prof Boisselier has developed a new ocular drug nanotechnology-based vector, in the form of ultrastable mucoadhesive gold nanoparticles onto which drugs can be encapsulated, to provide an efficient drug-vector formulation to delivering anti-inflammatory drugs, such as those prescribed after cataract surgery, to a mucoid surface such as the cornea.

Opportunities

Ultrastable mucoadhesive gold nanoparticules can efficiently deliver drugs to the cornea and significantly increase their residence time. SOVAR and Université Laval seek a partner for co-development or commercialization of this technology for ophthalmic applications.

Available resources

The laboratory of Prof Boisselier can synthesize, functionalize, and characterize ultrastable gold nanoparticles, as well as encapsultating drugs for in vitro and in vivo studies.
