Analytical characterization of engineered nanostructures - Techniques and challenges

초록

Numerous nanostructures with nanoscale dimensions smaller than 100 nm have been developed. These nanostructures, including those with promising uses, have novel physicochemical characteristics that affect the molecular and systemic levels of their physiological interactions. The need for analytical data relevant to manufactured nanomaterials is growing, necessitating the modification of current techniques and methodologies or the creation of new ones. The analytical sciences have faced a hurdle in recognizing nanoparticles as a novel class of analytes that include both chemical and physical information. It is also necessary to provide details on the physiochemical characteristics of nanoparticles and their changes. This article discusses primary available characterizing techniques to deal with engineered nanostructures for evaluating its quality and performances. The principle of each technique is included while indicating the strength and limitations in determining the physiochemical characteristics of engineered nanostructures. © 2024 Author(s).
