New Spectral Applications of the Fourier Transforms in Medicine, Biological and Biomedical Fields

Abstract

This chapter reviews some recent spectral applications of the Fourier transform techniques as they are applied in spectroscopy. An overview about Fourier transform spectroscopy (FTS) used like a powerful and sensitive tool in medical, biological, and biomedical analysis is provided. The advanced spectroscopic techniques of FTS, such as Fourier transform visible spectroscopy (FTVS), Fourier transform infrared-attenuated total reflectance (FTIR-ATR), Fourier transform infrared-photoacoustic spectroscopy (FTIR-PAS), Fourier transform infrared imaging spectroscopy (FTIR imaging), and their biomedical applications are described. A special attention has been paid to the description of the FTVS method of commercial quantum dots like an innovative and reliable technique used in the field of nanobiotechnology.
