Label-Free Biosensors
Label-free biosensors allow detection of small chemical molecules, DNA, proteins, viral particles, bacteria, and cells using intrinsic properties that each of these biomaterials have. Because label-free detection methods do not require attachment of fluorescent dye molecules or other enzyme-based tags to the analyte being detection, it is possible to perform very simple detection methods that can be used for pharmaceutical research, genomics, proteomics, disease diagnostic tests, and environmental monitoring. Our group is developing several different types of label-free biosensing methods that take advantage of the ways that biomaterials interact with electromagnetic fields associated with light. Key attributes of the sensors we develop are high sensitivity, high resolution, the ability to perform many biochemical experiments in parallel, and the ability to produce large-area sensors inexpensively from plastic materials.
