Beyond the Spectrum: Exploring Unconventional Applications of Fourier Transform Infrared (FTIR) Spectroscopy

Abstract

Fourier Transform Infrared (FTIR) spectroscopy, once primarily associated with structural analysis, has transcended its conventional role to become a versatile analytical powerhouse with applications spanning diverse fields. This review paper navigates the uncharted territories of FTIR's evolution, highlighting its innovative utilization in unconventional domains. Traditional applications of FTIR in structural analysis have expanded into captivating realms such as art conservation, nanotechnology, life sciences, and environmental monitoring. We delve into the transformation of FTIR into a tool for pigment identification in historical artworks, its role in probing nanoscale materials for composition analysis, and its emergence as a vital diagnostic tool in disease detection. Moreover, we explore how FTIR enables real-time air quality assessment, influencing urban environmental management. The synergy of FTIR with other techniques, the advancements in FTIR imaging, and its integration with bioinformatics contribute to the evolving landscape of applications. As FTIR continues to reshape the boundaries of knowledge and innovation, this paper serves as a tribute to its versatility, inspiring researchers to unlock new insights, collaborate across disciplines, and drive the progression of science.
