Abstract

The near-infrared (NIR) region (600–1100 nm) offers several advantages in comparison with the conventional ultraviolet/visible (UV/VIS) region for spectroscopic measurements and detection. The lack of commercial instrumentation impeded the development of NIR techniques for years. The advent of inexpensive photodiodes and diode lasers used widely by the telecommunication industry gave the necessary impetus for development of analytical NIR techniques. This article describes the fundamental properties of NIR fluorophores and absorbers and provides a comparison with conventional UV/VIS dyes. The various analytical applications developed in the past decade that have utilized the advantages offered by this region are described with a particular emphasis on bioanalytical uses.
