“…AgNPs can also be used as a biomaterial for antimicrobial studies. AgNPs of different sizes antimicrobial effect is size dependent and 1-10 nm AgNPs can interact with bacteria directly [34,55] uniform linoleic acid capped AgNPs AgNPs possessed nearly the same toxicity as antibiotic (kanamycin and erythromycin) [59] biosynthesised AgNPs from Carica Papaya peel extract 5 μg/ml concentration of AgNPs showed antibacterial activity [60] biosynthesised AgNPs from proteins of sea grass minimum concentration inhibition found at (0.24 nM; maximum activity=14.3-0.12 mm and minimum activity=11.2-0.38 mm) [61] radiation synthesised AgNPs small amount of AgNPs (21.81 μgm/cm 2 ) coated on cotton fabric exhibited antimicrobial effects [62] mycosynthesised AgNPs bacterial species were found sensitive at 20 mg/ml [63] AgNPs with silica and lignin hybrid materials inhibition activity was found at the highest concentration of 500 µg/100 µl [64] AgNPs with sponges AgNPs increased chitosan antimicrobial effects [65] AgNPs with coaxial nanofibres zone of inhibition measured as 13 and 11 mm [66] drug and AgNP complex tetracycline − AgNP complex inhibited because it released a higher amount of silver ions [67]…”

Silver nanoparticles (AgNPs) are widely utilised in the industry and health care. This review demonstrates an exhaustive report on the toxicity of AgNPs towards pathogenic microbes. AgNPs are the most abundant antimicrobial agent for bacteria than other species and less harmful to human cells than to bacterial cells. This report suggests the relatively high acute toxicity of AgNPs to the microorganism. In addition, the toxicity mechanism of AgNPs is briefly discussed.

This review presents an introduction to the synthesis of silver nanoparticles (Ag-NPs) by gamma irradiation method. This method offers some benefits over the conventional methods because it provides fully reduced and highly pure nanoparticles free from by-products or chemical reducing agents, and is capable of controlling the particle size and structure. The nucleation and growth mechanism of metallic nanoparticles are also discussed. The competition between nucleation and growth process in the formation of nanoparticles can determine the size of nanoparticles which is influenced by certain parameters such as the choice of solvents and stabilizer, the precursor to stabilizer ratio, pH during synthesis, and absorbed dose. The present review, summarizes the gamma irradiation synthesis of Ag-NPs procedure, advantages, applications and their antibacterial properties.

“…For example, triangular NPs can be obtained using ascorbic acid as a mild reductant [186] and Ag ions reduced on Au seeds can result in the synthesis of larger and more uniform AgNPs [188]. Gamma radiation can be used to produce reactive species in solvents that act as reducing agents to form stable colloidal Ag nanoclusters from Ag cations [189].…”

“…AgNPs have been used in different fields including catalysis, sensing and optoelectronics, although the most common application still relates to their use as antibacterial, antiviral and antifungal agents [184, 185, 189, 213]. As mentioned above, it is necessary to choose NPs of appropriate shapes and sizes for the intended applications.…”

Colloidal inorganic nanoparticles have wide applications in the detection of analytes and in biological assays. A large number of these assays rely on the ability of gold nanoparticles (AuNPs, in the 20 nm diameter size range) to undergo a color change from red to blue upon aggregation. AuNP assays can be based on cross-linking, non-cross linking or unmodified charge-based aggregation. Nucleic acid-based probes, monoclonal antibodies, and molecular-affinity agents can be attached by covalent or non-covalent means. Surface plasmon resonance and SERS techniques can be utilized. Silver NPs also have attractive optical properties (higher extinction coefficient). Combinations of AuNPs and AgNPs in nanocomposites can have additional advantages. Magnetic NPs and ZnO, TiO and ZnS as well as insulator NPs including SiO can be employed in colorimetric assays, and some can act as peroxidase mimics in catalytic applications. This review covers the synthesis and stabilization of inorganic NPs and their diverse applications in colorimetric and optical assays for analytes related to environmental contamination (metal ions and pesticides), and for early diagnosis and monitoring of diseases, using medically important biomarkers.
