This study is the first report that describes the use of an unmodified screen-printed carbon electrode as an efficient and streamlined sensor for the detection of Hyp. The highlight of this research is eliminating any need for complicated preparation and detection processes. The measurement relies on the indirect detection of Hyp by comparing the signal of Cu(II) ions in the absence and presence of Hyp, using a sequential drop mixture of the sample and Cu(II) in a basic condition. Key parameters related to square wave anodic stripping voltammetry (SWASV) for detection were systematically examined to improve sensitivity and accuracy. Under optimal conditions, the modification-free sensor offers good performance for Hyp detection with a linear range of 0.5–10 mM and a detection limit of 0.15 mM. In practical analysis, Hyp in the collagen supplement samples was detected with an acceptable recovery range of 80.36–107.89 % (<em>n</em> = 3). In addition, the results obtained from the suggested approach were validated against the conventional standard technique.
