My research interests are focused in the development of novel optical tools and lab-on-a-chip based analytical platforms.
My long term goal is to use such tools to evaluate and enhance the technologies tied to emerging cancer treatment techniques.

In order to achieve this goal, I will utilize my multidisciplinary experience with three major thrusts in:
1) Low-light microscopy and imaging techniques optimized for single-cell level radionuclide and bioluminescence imaging
2) Nanoliter droplet sensors for detecting radioactivity in encapsulated cells
3) Analysis of fluid biotransport properties in microfluidic environments

  • Humidity Effects on the Wetting Characteristics of Poly(N-isopropylacrylamide) during a Lower Critical Solution Transition LANGMUIR Chhabra, A., Kanapuram, R. R., Kim, T. J., Geng, J., da Silva, A. K., Bielawski, C. W., Hidrovo, C. H. 2013; 29 (25): 8116-8124


    Poly(N-isopropylacrylamide) (PNIPAM) is expected to find utility in tissue engineering and drug delivery, among other biomedical applications. These applications capitalize on the intrinsic lower critical solution temperature (LCST) of the polymer: below the LCST, enthalpic gain from intermolecular hydrogen bonding between PNIPAM and water molecules dominates the solvation; above the LCST, entropic effects resulting from the intramolecular hydrogen bonding between the carboxyl and amide groups of PNIPAM lead to water expulsion. The dependence of the LCST upon the molecular weight, solvent, and solution activity (i.e., solute concentration) has been studied extensively. However, what has not been previously explored is the effect of humidity on the characteristic properties of the polymer. Herein, we show that the relative humidity affects the water adsorption dynamics of PNIPAM as well as the magnitude of the transition that occurs at the LCST of the polymer. In short, the magnitude of the LCST transition decreases with an increasing relative humidity, and the time period over which adsorption occurs decreases with the temperature.
