| Abstract |
This talk presents the development of a molecularly imprinted polymer (MIP)-based optical fiber sensor for the sensitive and selective detection of methamphetamine. The sensor utilizes a single-mode?no-core?single-mode (SMF?NCF?SMF) fiber structure that enhances light?matter interaction through multimode interference, enabling real-time and label-free detection based on wavelength modulation. A methamphetamine-imprinted polymer synthesized via photopolymerization was coated onto the sensing region to provide molecular recognition and high chemical stability. The sensor demonstrated a linear response with a sensitivity of 1.59 nm/ppm, capable of detecting methamphetamine at concentrations below 1 ppm, which goes beyond the current limit of test kits. This innovation highlights the potential of integrating optical sensing and polymer imprinting technologies for rapid, portable, and non-invasive drug screening applications in forensic and healthcare settings. |
