“…The surface modification of AgNPs can also affect the oligodynamics effect of nanoparticles as surface modification can stabilize these nanoparticles e.g., modification of AgNPs with polyimide. There is a study that has proven half encapsulation of AgNPs with loosely polyimide can increase the antibacterial activity of these nanoparticles as well as improve the silver stability [55]. Coating with polydopamine and hydrofluoric acid etched glass spheres (PDA-HF/GSs) have shown strong adhesion towards E. coli and Bacillus [56].…”

Rapid development of nanotechnology has been in high demand, especially for silver nanoparticles (AgNPs) since they have been proven to be useful in various fields such as medicine, textiles, and household appliances. AgNPs are very important because of their unique physicochemical and antimicrobial properties, with a myriad of activities that are applicable in various fields, including wound care management. This review aimed to elucidate the underlying mechanisms of AgNPs that are responsible for their antiviral properties and their antibacterial activity towards the microorganisms. AgNPs can be synthesized through three different methods—physical, chemical, and biological synthesis—as indicated in this review. The applications and limitations of the AgNPs such as their cytotoxicity towards humans and the environment, will be discussed. Based on the literature search obtained, the properties of AgNPs scrutinizing the antibacterial or antiviral effect shown different interaction towards bacteria which dependent on the synthesis processes followed by the morphological structure of AgNPs.

“…Interestingly, many functional materials are reported to have multifunctional properties that can remove toxic chemicals and microorganisms simultaneously. Biological and chemical risks in water bodies often coexist and even promote each other in some cases. , Such materials exhibit great potential to simultaneously reduce the chemical and biological risks of water bodies and abate the effects of biofouling on the materials . Moreover, with the outbreak of COVID-19, the biosafety of water is now a serious global issue .…”

Currently, serious challenges to drinking water security remain. Toxic chemicals and opportunistic pathogens can trigger a grave health risks even in areas where the water supply system is relatively ideal. Antibacterial functionalization of water treatment technologies is introduced on the basis of the safety evaluation of microorganisms and chemicals. For water purification materials themselves, the introduction of an antibacterial function effectively ensures that they are prevented from being contaminated by microorganisms during long-term use. The antibacterial function of traditional water purification technologies can be realized through some modifications. The principle of some novel antibacterial approaches is summarized, which provides new inspiration for the precise design of environmental antibacterial materials. More importantly, attention is given to antibacterial modification methods and the effects between antibacterial function and the capture and/or degradation of pollutants. The application of multifunctional antibacterial materials in the purification, transportation, and storage of drinking water is also discussed.

“…Reports show that, half encapsulation of antibacterial AgNPs with loose polyimide enhances the anti-bacterial activity of AgNPs. [29][30][31][32] Report by Akhil et.al. demonstrated that, green synthesized AgNPs using Tectona grandis seed possess significant anti-bacterial activity against E. coli and S. aureus, where silver ions were found to be released by nanoparticles and are collected along the cell wall or within the cell, affecting DNA replication.…”

Nanoparticles (NPs) a potential next generation candidate for human well-being in the world of healthcare, have been observed to be effective anti-bacterial agents. The significance of nanoparticles as anti-bacterial agents has taken spotlight, due to the inability of pathogenic bacteria to develop resistance against NPs. In this review, mode of action of some scientifically important anti-bacterial NPs were discussed, along with summary of recent pre-clinical and clinical studies reported on anti-bacterial NPs are discussed. Some of the current hurdles and barriers that should be addressed to complete marketability and human applications, in regards to NPs as nanomedicines are also critically discussed along with focus on reported toxicity in NPs. Some additional pharmaceutical effects of NPs, reported in the recent years, such as antidiabetic and anticancer are also included for discussion. This review provides significant information on recent discoveries in the field of nanomedicines as antibiotics, that show promising future for drug development and drug delivery. As in every human domain, evidence begins to point to the actual undeniable fact that in conjunction with the existing medicine, nanomedicines could be the future of the healthcare that replace or enhance the potential current pharmaceutical drugs.
