    Verduzco Laboratory Overview

     

    While the general term ‘nanotechnology’ oftentimes refers to work involving nanomaterials such as fullerenes, carbon nanotubes, and quantum dots, the Verduzco laboratory focuses on nanotechnology using materials that have been known and studied for a long time. Polymers are ubiquitous in commercial applications and several textbooks have been devoted to the physical and chemical properties of polymers, but by reconfiguring and rearranging polymers at the nanoscale, remarkable new properties emerge. These types of nanoscale materials open the door to advanced applications such as high-density memory storage, polymeric assemblies for targeted drug delivery, polymeric photovoltaics, fuel cells, among other applications. The advantages of using more conventional materials like polymers is that their basic properties have been established, their toxicity is known, and the potential for direct application is more feasible. The challenge in polymer nanoscience is exploring the vast combinatorial playground enabled by modern synthetic polymer chemistry in an efficient way to uncover fundamental knowledge that will be the source of future applications or new materials which can be directly applied to solve longstanding engineering problems.
