Abstract
Detection of biologically relevant substances is an important aspect of interdisciplinary research with aim to specifically, selectively and efficiently determine the presence of various analytes. In our research, we test the concept of applying patterned silver nanostructures featuring plasmon resonance for efficient fluorescence – based detection of photoactive proteins. We will describe the recent results about controlling spatial position of plasmonic paths made of silver islands, as well as of silver nanowires. Detection protocol is based on real-time imagining using wide-field fluorescence microscopy, which allows for observing emission of individual proteins. The approach is universal and applicable for variety of analytes.
