Titanium dioxide-polyaniline/silk fibroin microfiber sensor for pork freshness evaluation

A novel and low-cost micro-sensor with a diameter of 12 μm was developed based on Titanium dioxide-Polyaniline/Silk fibroin fiber (TiO2-PANI/SFF). TiO2-PANI composites were deposited on surfaces of SFFs by in-situ polymerization. The microfibers were characterized by Scanning electron microscopy (SEM), Energy dispersive spectrometer (EDS), Raman spectrometer, Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD), and the...
