This study explores the use of hyperspectral imaging (HSI) in the shortwave infrared (SWIR) range for non-destructive detection and classification of biofilms on thermoplastic polyurethane (TPU) surfaces. Multi-species biofilms composed of <i>Comamonas</i> sp., <i>Raoultella</i> sp., and <i>Escherichia coli</i> were formed at 10°C and 25°C and biofilm protein and polysaccharide contents were determined. Principal Component Analysis (PCA) and Partial Least Squares Discriminant Analysis (PLS-DA) were used to differentiate among four classes of TPU coupons, including blank (BLANK), control (CTRL), intermediate-strength biofilms formed at 10°C (S10), and strong biofilms formed at 25°C (S25). PCA successfully clustered samples based on spectral profiles of the classes, identifying significant wavelength regions at 1451 and 1926 nm, which correlated with the water, protein, and polysaccharide content of multi-species biofilms. PLS-DA provided a classification accuracy ranging from 68% to 100%, with the highest classification accuracy (100%) observed for BLANK and biofilm-contaminated (S25) TPU coupons and the lowest accuracy (68%) for CTR.
