Optically active nanomaterials have been extensively developed in the last two decades for their potential applications in the field of sensing and biosensing, imaging, drug delivery, fabricating optoelectronic devices, disease diagnosis, and monitoring, etc., because of their unique and superior optical properties over the organic dyed variety. In the field of sensing and biosensing, nanomaterials such as SPR active noble metal nanoparticles, fluorescent metal nanoclusters, semiconductor QDs, carbon nanomaterials, metal oxides etc., are widely utilized for the designing of sensing probes. This book aims to critically summarize the potential sensing applications of optically (chromogenic and fluorogenic) active, nano-sized organic and inorganic materials for the selective detection of ionic analytes (such as metal ions and anions), in various environmental and biological samples. A thorough discussion will be had on the design, synthesis, sensing mechanisms, and applications for detecting ionic analytes. Each chapter deals with the sensing applications of one kind of nanomaterial. This book is an important reference source for materials scientists and engineers seeking to increase their understanding of how nanomaterials are being used for sensing applications.
Chemistry has become an important tool in solving problems in biology and medicine. Chemists are engaged in developing new devices at the nanoscale level to aid in clinical diagnosis, real time monitoring of analytes, and analyzing neural activity, etc. Our research is aimed at designing and synthesizing fluorescent sensors to detect various divalent metal ions under physiological conditions. We designed and synthesized a chemosensor based on the principle of photoinduced electron transfer as a signal transduction mechanism in order to detect the presence of various divalent metal cations, particularly zinc. We report the synthesis, characterization and its spectrophotometric titrations with various metal ions. This sensor signals the presence of metal ions by a fluorescence signal and offers a significant advantage as it exhibits "off-on" behavior in the presence and absence of metal ions. The primary sensor was found to be very sensitive and selective toward zinc ions. We also aimed at optimizing the performance of this chemosensor by taking advantage of electron donating/withdrawing abilities of different functional groups by using computational methods. We devised a new scheme to synthesize it, unfortunately the modified sensor was not realized for unknown reason. We are currently involved in devising an alternate strategy to synthesize and develop new sensors for neutral molecules.
