About this Research Topic
Noble metal nanomaterials exhibit unique and intriguing physicochemical, optical, electric, magnetic, and catalytic properties to support their versatile functions and applications. Generally, the functional features of noble metal nanomaterials are closely associated with their morphology, size, composition, nanostructure, surface modification, and assembled behavior. In principle, the properties of noble metal nanomaterials are accurately determined by engineering any one of these factors, thereby facilitating the design flexibility, tunability, and diversity of noble metal nanomaterials for bioanalytical applications. In particular, with the rapid development of interdisciplinarity research activities, the precise and smart control of synthesis, design, modification, and functionalization of noble metal nanomaterials has emerged in recent years as a promising strategy to endow their tunable properties, thus allowing them to be capable of acting as a high-performance labeled probe for biosensors and bioimaging. Increasingly emergent bioanalytical approaches enabled by the engineered noble metal nanomaterials have been extensively developed for the food safety inspection, environmental monitoring, as well as disease diagnostics, and control. The sensitivity, specificity, rapidity, and portability of both conventional and newly-developed analytical technologies are substantially enhanced by noble metal nanomaterials, and these advances are important for improving the capacity to respond to the known/unknown and ever-increasing threats to human health both in developed and developing countries.
