In this work, we have demonstrated metal ion detection using L-Cysteine functionalised gold-coated tilted fiber Bragg grating (Au-TFBG). L-cysteine (L-cys) is a semi-essential amino acid that has high tendency to form Au-S bond via thiol group on the gold surface of the sensor whereas the amine grou...
