Fluorescence microscopy has experienced tremendous growth over the past four decades and has facilitated major advancements in science. The classic fluorescent techniques (which include epifluorescence and confocal) allow researchers to selectively observe labeled structures with great clarity and consistency. Historically, biological scientists have been the most prolific users of fluorescence imaging. However, growing numbers of nano-materials research initiatives are now incorporating quantum dots and other fluorescent labels into their imaging protocols. This is especially true in areas where nano-materials and biological research is overlapping such as drug delivery. This nano-bio convergence, along with other advancements, has generated the need to observe highly dynamic events involving labeled and unlabeled structures in real time.
