Abstract

With increases in the global population, several new, life-threatening diseases caused by various pathogens have come into existence. Some of the deaths from such diseases are primarily due to a delay in making the diagnosis, the side effects of drugs, and the material needed for rapid detection, prevention or cure [1]. Further, an increased number of pollutants arising due to excess use of chemicals have led to increases in mortality rates. There is, thus, an urgent need for the development of rapid sensing methods to monitor and control the release of contaminants and pathogens [2].
