Enhanced Electrocatalytic Performance of Eco-friendly Nanomaterial-Based Sensors for the Analysis of Pharmaceutically Important Compounds

Abstract

Green synthesis is a sustainable alternative to traditional chemical methods for nanomaterial-based sensors because it is more affordable, scalable, and does not involve any harmful contaminants when using green materials’ extracts as stabilizing and reducing agents for nanoparticle synthesis. The green-synthesized nanoparticles are extremely attractive for various pharmaceutical applications. This review article examines the most preferred eco-friendly nanomaterials, their synthesis and characterization, and their pharmaceutical applications based on the selected studies conducted in the last five years. It concludes that the green synthesis methods allow the transformation of metals into nanoparticles or green materials that act as precursors to carbon-based nanomaterials. The nanoscale materials obtained through green synthesis methods contribute to low toxic, environmentally benign, easy, and low-cost sensing and enhanced electrocatalytic performance.
