(ATR FT-IR) spectroscopy combined with machine learning (ML) techniques to differentiate between individuals who had used fentanyl and those who had not (1). The results not only validate the efficacy of this approach but also demonstrate a new method for advancements in fo...
As seen in Fig. 2B, water has a strong IR absorbance around 1640 cm–1 (H–O–H bending), which overlaps with the Amide I mode of BSA (1700 cm–1 and 1600 cm–1). Despite these experimental challenges, we succeeded in acquiring BSA spectra over the pH range of interest ...
