GIT Uses Nanosight To Study Drug-Delivery Nanogels
Georgia Institute of Technology is using the Nanosight LM-20 to help characterise dimensional changes of nanogels used to develop drug-delivery vehicles for macromolecular therapeutics. Prof Andrew Lyon's research group, from GIT's School of Chemistry and Biochemistry, is working on the development and implementation of new, environmentally responsive (or 'smart') materials for photonic materials, bioanalysis and biomimetics. The group is designing hydrogel nanoparticles that undergo large changes in their chemical, mechanical, optical or electrical makeup in response to a chemical stimulus, biomolecular interaction, or electromagnetic field; such materials can be viewed as amplifiers or sensitisers of the environmental event. As a result of their environmental sensitivity, nanogels have potential in many applications. The principal user is PhD candidate Michael Smith, who said: 'The Nanosight has been an enabling tool for us in the characterisation of dilute nanog...
