[1][4] The main focus of Tan's group is in the field of DNA aptamers, molecular recognition and nano biosensors.
The Tan group has pioneered the Whole-Cell Systematic Evolution of Ligands by Exponential Enrichment method (SELEX).
This fundamental tool is used to select aptamer molecules against specific cell-lines for a wide range of applications.
A variety of high sensitive aptamer-based molecular designs have been developed by Tan group and contributed to theranostic and bioanalysis studies.
[1][6] Tan has served on many national and international research program committees, and also several Editorial and Advisory Boards, including ACS Nano and Analytical Chemistry.
