11/25/2023 0 Comments Spectroscopy ftirEach molecule has a spectrum fingerprint that makes it unique and allows it to be distinguished from other molecules. FTIR spectroscopy studies the interactions between matter and electromagnetic radiation that appear in the form of a spectrum. Hence, the pressing need for new, fast, and precise analysing techniques.įourier transform infrared (FTIR) spectroscopy is a field that has undergone significant development over the past decade, promising easier, more rapid, and more objective diagnoses. Finally, CBC limitations are related to the manual examination of blood smears, difficulty recognising abnormal red cell shapes (such as fragmented cells), and high running costs. Electrophoresis requires a large sample for the assays, as well as high analysis precision. ELISA limitations are related to the cost of the assays due to the use of antibodies, the risk of cross-reactivity, the high background noise, and extended analysis time. In ultraviolet–visible (UV–VIS) spectrophotometry, the main limitation is the requirement for sample and setup preparation time to avoid light interferences. However, all of these methods have limitations. The primary, commercially available measuring techniques for such devices are spectrophotometry, enzyme-linked immunosorbent assay (ELISA), electrophoresis, and blood cell counting or complete blood count (CBC). Meanwhile, viruses, bacteria, and fungi are rapidly evolving, pushing further the need to develop new, quick, and reliable diagnostic tools. Diagnostic devices currently available on the market rely on the same measuring techniques developed in the last century (mainly spectrophotometry or electrochemical assays).
