Re-exploring silver nanoparticles and its potential applications

Effects of Silver Nanoparticles on the Red Microalga Porphyridium purpureum CNMN-AR-02, Cultivated on Two Nutrient Media

“…Mar. Drugs 2024, 22, x 2 of 15 microalgae for biofuel production purposes [10][11][12]. However, this effect is more often a result of the stress caused by high concentrations of these nanoparticles.…”

“…In the context of applying stimulants to produce higher amounts of biomass with a valuable and predictable biochemical content, nanoparticles of various natures are increasingly being explored from this perspective [8,9]. For example, nanoparticles of Mg, Al, Zn, Cu, Pb, Ag, Fe, Fe 3 O 4 are used as effective stimulants to enhance lipid synthesis in microalgae for biofuel production purposes [10][11][12]. However, this effect is more often Mar.…”

“…Silver nanoparticles (AgNPs) are among the most actively used in various fields, such as the food industry, agriculture, textile industry, medical industry, and phycobiotechnologies, including for the valorization of Porphyridium purpureum biomass [8,11,[17][18][19]. Thus, AgNPs are used as stimulants for biosynthetic activity, primarily lipids, the content of which can increase in microalgal biomass by 3-8 times [15,18].…”

Review of Oxidative Dissolution and Sulfidation of Select Nanoparticles in the Environment: Impact on Applications

“…7 The majority of NPs utilized in consumer products are metal and metal oxide NPs. Metallic NPs, such as Ag NPs, are extensively used for their antimicrobial properties in wound dressings, 2 drug delivery, 8,9 textiles including clothing, 3,10,11 and food packaging. 4,12 They also differ from their bulk counterpart which is largely inert as Ag NPs have high reactivities and have been used for the catalytic synthesis of organic compounds 1 in addition to the degradation of pollutants in water.…”
