The development of an instant on-site selective visual detection system for trinitrotoluene (TNT) is a critical need for a secured society and a greener environment. Despite momentous advances in the field, a portable and reliable method for quick and selective detection of TNT still poses a challenge to many reasons including inappropriate usage in subordinate areas and untrained personnel.
Dr Anitha Senthamizhan and Dr Asli Celebioglu are demonstrated in this article for the first time selective, on-the-spot detection of TNT at sub-ppt level using a single nanofiber embedded fluorescent gold cluster hybrid system under the supervision of Assoc. Prof Tamer Uyar. The enhanced stability of the developed platform makes more interesting for outdoor application. The added flexibility of the hybrid system allows the nanofibers to be coated on any substrate as per our needs, such as cover slips, silicon wafers, aluminum foil, etc. Moreover, this nanofibrous hybrid system is relatively trouble-free and does not require any auxiliary alteration which makes it accessible even to an inexperienced person.
