Meet Md Maksudur Rahman, a recent Ph.D. graduate in analytical chemistry from the University of Wyoming, WY, USA. Under the guidance of Dr. Caleb M. Hill, Md’s doctoral research focused on the development of electrochemical sensors and biosensors using scanning electrochemical cell microscopy (SECCM). Specifically, he fabricated well-ordered single-entity nanoparticle arrays (AuNPs and AgNPs) and applied them to the field of electrocatalysis and biosensing. Md’s research interests lie in the electrochemical fabrication of single entities using various scanning probes techniques like SICM, SECM, and SECCM.
