Dr. JORGE L. CHOLULA-DÍAZ
I am a research professor at the School of Engineering & Sciences at Tecnologico de Monterrey.
​
My research interests are focused on the synthesis, characterization and application of nanostructured materials, specifically on:
-
Transition metal oxides (CuO, Cu2O, ZnO, SnO2)
-
Noble metal nanocrystals (Ag, Au, Pd, Pt)
OUR LATEST RESEARCH
Bimetallic silver/gold nanosystems are expected to significantly improve therapeutic efficacy compared to their monometallic counterparts by maintaining the general biocompatibility of gold nanoparticles (AuNPs) while, at the same time, decreasing the relatively high toxicity of silver nanoparticles (AgNPs) toward healthy human cells.
Thus, the aim of this research was to establish a highly reproducible one-pot green synthesis of colloidal AuNPs and bimetallic Ag/Au alloy nanoparticles (Ag/AuNPs) using starch as reducing and capping agent. The Ag/AuNPs were tested for several anti-infection and anticancer biomedical applications.
Glucose determination is an important molecule for different fields, being the clinical analysis the most common for the prevention and treatment of diabetes. Non-enzymatic glucose sensors are being studied to reduce the effect of the structural changes of glucose oxidase enzyme (GOx) that alter the results in glucose determination. Nevertheless, the materials developed for this application are noble metals that represent high costs for the construction of this sensors, thus more affordable materials with same performance are desired.
In this work, a modified carbon paste electrode (CPE) with Cu2O nanocubes was developed for direct glucose detection.
