Strategies Employed to Design Biocompatible Metal Nanoparticles for Medical Science and Biotechnology Applications

“…This configuration exhibited metalenhanced fluorescence (MEF) and enhanced Raman signal amplification. 126 Additionally, Dong et al (2023) investigated bimetallic nanocomposites comprising Au and Ag with SiO 2 shells. This composite structure was designed to enhance fluorescence signals by combining the stability of AuNPs with the enhanced scattering efficiency of Ag, thereby contributing to improved overall performance.…”

This configuration exhibited metal-enhanced fluorescence (MEF) and enhanced Raman signal amplification . Additionally, Dong et al (2023) investigated bimetallic nanocomposites comprising Au and Ag with SiO 2 shells.…”

Unveiling the Potential of Bioinoculants and Nanoparticles in Sustainable Agriculture for Enhanced Plant Growth and Food Security

“…Furthermore, higher secondary metabolite synthesis and nutrient intake strengthen plants' resistance to plant pathogens. In particular [36], the introduction of silica nanoparticles causes an increase in the plant cell wall thickness and strength in maize (Table 3). It provides an additional layer of defense against predatory insects and the invasion of plant pathogens.…”

“…When used in situations where they may serve as both a solvent and a reactant, nonaqueous solvents have made possible a novel approach to the production of nanoparticles. The hydrolysis of certain alkoxides can be used on an industrial scale to produce silica and other oxides [36,65]; however, rather than utilizing one reactor, it is more common to use a number of smaller reactors.…”

“…Manufacturing mesoporous silica NPs can help regulate discharge since the pores prevent molecules from leaving [7]. It has also been reported that the usage of silica nanoparticles in agriculture can boost the survival of maize seeds when they are included in preparations of smart pesticides and can enhance bioremediation [36]. The most prevalent techniques for synthesizing SiO 2 nanoparticles are reverse microemulsion, FAME synthesis, and the sol-gel technique.…”
