Simulated fingerprint reference test strip

Abstract

A simulated fingerprint reference test strip includes a substrate and a deposition structure. The deposition structure is formed on the substrate by applying an artificial secretion to the substrate and then drying it. It includes a distribution outline corresponding to a simulated fingerprint, which is then processed by a fingerprint enhancement reagent to reveal the corresponding simulated fingerprint pattern. This provides a standardized reference test strip suitable for testing and comparing the development effects and sensitivity of different fingerprint enhancement reagents, and for observing the development of simulated fingerprint patterns at different magnifications and under different deposition density conditions, thereby helping to improve the reproducibility of fingerprint enhancement reagent test results.
