Brief Introduction

Tools to follow biomolecules (proteins, DNA/RNAs, lipids, etc ) have greatly increased our understanding on how the nature precisely controls biological processes. Researchers want to locate, quantitate, and also control the target biomolecule under hopefully any circumstances; in tubes, inside cells, or only in cancer cells. In addition, the target molecules are generally with many other molecules around (such as in the cellular context), requiring specific probes which can help us to follow only those targets. The main purpose of our research is to create our own biochemical probes, and apply them for the development of new bioanalytical tools, by which offering unprecedented and distinct ways to study life science. Primary biomolecule targets are several aberrant forms of nature that are highly important for cellular regulation and disease occurrence; while their bioanalysis has been restricted by lack of proper analytical handles.
