An enhanced safrole sensing performance of a olyacrylonitrile nanofiber-based-QCM sensor by overlaying with chitosan

We report on a method to enhance the sensing performance of polyacrylonitrile (PAN) nanofiber-based QCM sensor overlaid with chitosan. The PAN nanofibers were deposited on the QCM sensing surface by electrospinning technique followed by overlay with chitosan by a drop-casting method. The Fourier tra...
