摘要

Molecularly imprinted polymers (MIPs) are synthetic receptors designed to recognize targeted molecules. This study demonstrates the fabrication of MIP films using Leptospira bacteria as templates, challenging conventional imprinting processes due to the small, elongated, and complex bacterial morphology. Leptospira bacteria were embedded onto poly(MMA-co-HEMA) prepolymer surface and polymerized under UV light. After template removal, the successful imprintments of Leptospira bacteria were observed onto the polymer surface, maintaining their unique spiral long morphologies. The bacterial cells tend to overlap, leading to a lack of clarity. The imprinting of complex bacterial morphologies could establish a foundation for developing a specific bacterial recognition system.
