Background

Ruben Morones was born in Mexico City, Mexico. He received his B.S. in Chemical Engineering in 2003 from Universidad Autonoma de Nuevo Leon, the second largest state university of Mexico. As an undergraduate he researched in the area of catalysis for the improvement of NOx reduction in three way catalytic converters. The research was conducted under Dr. Gustavo Adolfo Fuentes and was part of two summer research programs in the Universidad Metropolitana in Mexico City. He is currently pursuing his PhD at the University of Texas under Dr. Wolfgang Frey and Dr. Nicholas Peppas.

Research Summary

My PhD research focuses on the use of silver nanoparticles for biological applications. Noble metal nanocrystals exhibit size dependant electromagnetic, catalytic and optical properties. The exploration of these properties applied in developing cell specific drug delivery devices is the main goal of my research.

Devices that are able to release different compounds at well defined multiple locations are extremely powerful tools in the areas of therapeutics and biological research. The objective is to design a microfluidics system that will integrate light responsive porous polycarbonate membranes to deliver multiple or single chemical components and study the reaction of individual cells.

The responsive component of the porous membranes is triggered by responsive polymers grafted in their pore walls. Since a copolymer responsive to light and temperature is employed, the silver nanostructures will be incorporated in the system to enhance the response of the polymers in two ways. The silver nanoparticles present a phenomenon called surface plasmon resonance where the surface electrons of the particle move collectively with specific wavelengths. When these electron relax from their excited form they free energy by scattering and by heating their surrounding environment. This will allow and enhancement in temperature sensitivity and the increase in light absorption will enhance the light sensitivity of it. Using these two mechanisms we will be able to change the permeability of the pores and allow cell specific delivery of the components to study the reaction of the individual cell.
