个人简介
Dr. Mingxu You is the principal investigator of the lab. He joined the University of Massachusetts at Amherst as an Assistant Professor of Chemistry in September 2016. He is now also a faculty member of Institute for Applied Life Sciences, Chemistry-Biology Interface Program, Molecular & Cellular Biology Graduate Program, Center for Biological Physics, Center for Clinical and Translational Sciences, and Center for Autonomous Materials at UMass.
Mingxu grew up in Heilongjiang, China. He received his B.S. degree in Chemistry from Peking University in 2008, and his Ph.D. degree in Chemistry from the University of Florida in 2012. During his doctoral study under the direction of Prof. Weihong Tan, Mingxu focused on developing DNA-based devices for cancer diagnosis, targeted drug delivery, and cell membrane biophysical studies. Prior to join UMass, he pursued his postdoctoral research with Prof. Samie R. Jaffrey at Weill Medical College of Cornell University, interested in developing RNA-based fluorescent sensors for imaging metabolites and signaling molecules in live cells.
Dr. You has co-authored over 70 journal articles and 3 book chapters. Most of his work has been published in top journals including Nature Nanotechnology, Nature Chemistry, PNAS, JACS, Angewandte Chemie, Nano Lett, ACS Nano, Anal Chem, and Chem Sci. His work has been highly recognized with over 5,000 citations. In addition, he has given over 30 invited seminars in top universities and research institutes in the U.S. and China.

研究领域
(1) Biosensors and Bioimaging
Spinach1Microscopy becomes a central tool to study the spatial and temporal dynamics of cellular components. Our research focus is to engineer imaging probes to quantify and track the synthesis, function, and degradation pathways of metabolites, signaling molecules, antibiotics, and other small molecules in live cells. These imaging probes will be constructed based on our knowledge about conditional self-assembly of nucleic acid nanostructures and integrated circuits.
(2) Cell Membrane Biophysics
We recently developed an efficient lipid-based approach to immobilize designer DNA probes outside of live cell membranes. With this approach, we are developing novel DNA probes that can measure transient membrane lipid encounter events and other biophysical events at cell membranes, such as cellular mechanotransduction.
(3) DNA/RNA Nanotechnology
DNA/RNA nanotechnology has succeeded in constructing precisely-defined nanostructures and nanodevices in vitro. Nucleic acid tools are great choice to study biology, especially considering their programmability of sequence-specific self-assembly and innate biocompatibility. Our research focuses on the construction of genetically encoded RNA nanostructures in live cells. We are interested in discovering novel molecular mechanisms for precise conditional self-assembly of these nucleic acid nanostructures.
(4) SELEX
Aptamer is single-stranded DNA or RNA that can specifically recognize a target of interest. Systematic evolution of ligands by exponential enrichment (SELEX) is a high-throughput technique to generate these functional nucleic acids. Our research interest is to identify aptamers and catalytic RNAs that function inside live cells. These identified RNAs or DNAs will be further applied to construct artificial biological devices and pathways that does not exist in Nature.
(5) Photo-controlled Devices
(2)Light can be used to externally manipulate the functions of nanodevices with both spatial and temporal precision. The use of light to control intracellular structure and function of proteins is generally termed optogenetics. We are interested in developing optogenetically controlled RNA devices by taking advantage of photoswitchable chromophores.
