James Fletcher, PhD Associate Professor |

Each student project in the Fletcher lab involves the preparation of organic or organometallic small molecules for a variety of applications. Students who work with the Fletcher group will learn common techniques synthetic chemists use to prepare, isolate, purify and characterize small molecules. Some projects additionally involve running assays to measure biological activity or sensor activity, and the optoelectronic characterization of new compounds. Currently active projects include: • Development of new fluorescent chemosensors and assaying for activity towards ionic and organic analytes of biological relevance • Design and synthesis of biologically active small molecules and testing for antimicrobial and enzyme inhibitory properties • Preparation and characterization of organometallic complexes for applications in bio-imaging and drug delivery Selected recent publications: |
