About this Research Topic
Metallic Nanoparticles are great candidates to create breakthroughs in the field of Analytical Chemistry. When the size of a material is reduced to the nanometer range, surface effects become very pronounced, especially due to the electron confinement and plasmonic effects. The use of nanostructured materials for fabrication of electrochemical devices with fast communication has attracted a considerable attention from the scientific community due to the possibility of facilitating the electron transfer of many redox reactions. Moreover, the localized surface plasmon resonance effect (LSPR) improves the selectivity and sensitivity of molecules in spectroscopy methods. By using a suitable size and surface chemistry, these metallic nanoparticles can be perfectly integrated into a variety of technological platforms, offering novel physical and chemical properties for the high-performance analytical devices. Although the exploitation of optical and electrical properties of metallic nanoparticles in the Analytical Chemistry field is a reality nowadays, there are always challenges associated to their applicability such as, repeatability, reproducibility and selectivity.
In this scenario, the main goal of this Research Topic is to bring together researchers to share their recent results on the use of metallic nanoparticles to improve their analytical (bio)sensors.
