“…However, it has been suggested that various biomolecules are involved in this process [24,[38][39][40][41][42][43][44][45][46][47][48]. Capping and stabilizing agents (polysaccharides, polypeptides and other bioorganic compounds) prevent the gNPs from further growth and agglomeration in resulted colloidal solution [45][46][47][48][49][50][51]. Extracellular synthesis of gNPs usually occurs when microbial cells secrete reductive enzymes on the surface of cell wall or outside the cell [43,[45][46][47][48].…”

Novel nanomaterials, including metallic nanoparticles obtained via green synthesis (gNPs), have a great potential for application in biotechnology, industry and medicine. The special role of gNPs is related to antibacterial agents, fluorescent markers and carriers for drug delivery. However, application of gNPs for construction of amperometric biosensors (ABSs) is not well documented. The aim of the current research was to study potential advantages of using gNPs in biosensorics. The extracellular metabolites of the yeast Ogataea polymorpha were used as reducing agents for obtaining gNPs from the corresponding inorganic ions. Several gNPs were synthesized, characterized and tested as enzyme carriers on the surface of graphite electrodes (GEs). The most effective were Pd-based gNPs (gPdNPs), and these were studied further and applied for construction of laccase- and alcohol oxidase (AO)-based ABSs. AO/GE, AO-gPdNPs/GE, laccase/GE and laccase-gPdNPs/GE were obtained, and their analytical characteristics were studied. Both gPdNPs-modified ABSs were found to have broader linear ranges and higher storage stabilities than control electrodes, although they are less sensitive toward corresponding substrates. We thus conclude that gPdNPs may be promising for construction of ABSs for enzymes with very high affinities to their substrates.

Attracted materials nanostructures consist of bismuth ferrite strong attention to being a candidate optimistic in many applications due to perovskite structure as aspect of relevance to electronic structure and chemical bonding. This review article focuses on recent developments regarding the synthesis, characterization, and applications of BiFeO3 nanostructures.The synthesis of bismuth ferrite with different morphologies phases parameters as exhibits multi-ferroic properties of both ferroelectric ordering and antiferromagnetic ordering which is useful for applications in memory, spintronic photovoltaics and magneto-electric sensor devices. Based on account of advanced characteristics like electrical resistance, the multiferroic BiFeO3 nanomaterials are emerged to be a tough challenger in the several physiochemical research area in comparison to the other inorganic perovskites nanostructures.

“…1,2 There is a wide range of nanostructured materials with potential applications in food production and preservation, which can be classified as zero-dimensional, one-dimensional, two-dimensional and three-dimensional nanomaterials. [3][4][5] Carbon dots (C-dots) are zero-dimensional nanomaterials with characteristic dimensions in the range 1-10 nm. Currently, C-dots represent a promising alternative to metal-based and colloidal nanoparticles for in vitro/ in vivo applications, including catalysis and energy fields, sensor and biosensors, electromagnetic interface shielding, bioimaging, gene transmission, drug delivery, and food production.…”

BACKGROUND: Carbon dots (C-dots) with antimicrobial activity were synthesized from the white mulberry extract with the aim of fabricating anti-listeria nanopaper using bacterial nanocellulose (BNC). Highly dispersed synthesized C-dots with a size smaller than 10 nm (approximately 4.9 nm) were impregnated into BNC by an ex situ coating method and then mechanical, morphological, UV-protectant and antibacterial activity were assessed. Randomized response surface methodology using a central composite design was applied to investigate the optimized concentration of C-dots in the BNC membrane.RESULTS: An optimized nanopaper including C-dots at a concentration of 530 g L −1 and an impregnation time of 14 h at 30°C with significant antimicrobial activity on Listeria monocytogenes was designed. The addition of C-dots into BNC significantly increased ultimate tensile strength and decreased strain with respect to breaking BNC. A BNC sheet with high-efficient UV-blocking property was prepared using C-dots.CONCLUSION: Based on the results, the designed nanopaper shows a substantial capacity with respect to the fabrication of antimicrobial/UV-blocking sheets for food active packaging.
