Synthesis of Bimetallic Nanoparticles and Applications—An Updated Review

Abstract

The manipulation of matter at the atomic level (nanotechnology) has experienced an explosion in research interest in recent years. Bimetallic nanoparticles are vital due to their high biocompatibility, stability and comparatively less toxicity. The synthesis methods that include physical, chemical and biological methods are explored and explained in detail, along with their advantages. They have a wide range of applications due to their synergistic properties including biological applications (in medicine and agriculture), environmental application (in water treatment and removal of toxic contaminants), engineering application (in nanosensors, nanochips and nano-semiconductors) and chemical and physical application (in optics, catalysis and paints). The green synthesis approach is a promising method of synthesis that can give rise to more biocompatible and less toxic bimetallic nanoparticles due to increasing environmental pollution. However, despite these interesting attributes of bimetallic nanoparticle, there is still much work to be done to improve the biocompatibility of bimetallic nanoparticles because of their toxicity and potentially hazardous effects.

Nanoparticles in Electrochemical Immunosensors – A Concept and Perspective

“…Common synthetic methods for synthesizing multiMeNPs are the electrochemical and chemical methods [89,90] . Adopting the classification made by D. S. Idris and A. Roy, [91] the last ones could be grouped into two other large classes of methods: simultaneous reduction and successive reduction methods. Both methods are simple, fast and cheap, moreover, NPs properties (e. g., shape and dimensions) may be tuned by varying pH, temperature, or precursors’ concentration.…”

Green synthesis trends and potential applications of bimetallic nanoparticles towards the sustainable development goals 2030

“…Although there exist reported studies that imply the use of metallic nanoparticles in the Sustainability Agenda affairs, there are still no review articles that directly link the use of these nanostructures towards accomplishing the SDGs. 11–14 Taking into account the enhanced properties that BMNPs exhibit towards a wide variety of applications and that nanomaterial-based products have been available in the market since the past decade 15 and the need for more sustainable synthesis methods as well as long-term risks and hazards that these nanomaterials may cause, this review outlines the green synthesis trends of BMNPs whose application aligns with SDGs 3, 6, and 12. We describe the properties and characteristics of the NPs depending on their structure, possible chemical composition, and way of synthesis to indicate their advantages and disadvantages.…”

Recent Advances in Synergistic Effect of Nanoparticles and Its Biomedical Application

“…It has been determined that BMNPs can contribute to the achievement of several of the UN SDGs, such as excellent health and wellbeing, clean water and sanitation, and responsible consumption and production, with a focus on problems and solutions [ 23 , 24 , 25 ]. While there is research that suggests that metallic nanoparticles could be useful in Sustainability Agenda initiatives, no reviews exist that establish a direct correlation between these nanostructures and the UN SDGs [ 26 , 27 , 28 , 29 ].…”
