“…The strong relationship between size and properties of nanoparticles has offered countless opportunities for many scientific breakthroughs. The extremely surprising activities of nanoparticles have enormous potential for modern technology emphasizing their use in human wellbeing (Heiligtag and Niederberger 2013;Mullai et al 2013). In recent times, the green chemistry procedure which utilizes microorganisms and plants for nanoparticles preparation has turned as a viable alternative to conventional physicochemical methods since it is facile, rapid, cost-effective, and environmentally benign.…”

This study was aimed to isolate soil fungi from Kolli and Yercaud Hills, South India with the ultimate objective of producing antimicrobial nanoparticles. Among 65 fungi tested, the isolate, Bios PTK 6 extracellularly synthesized both silver and gold nanoparticles with good monodispersity. Under optimized reaction conditions, the strain Bios PTK 6 identified as Aspergillus terreus has produced extremely stable nanoparticles within 12h. These nanoparticles were characterized by UV-vis. spectrophotometer, HR-TEM, FTIR, XRD, EDX, SAED, ICP-AES and Zetasizer analyses. A. terreus synthesized 8-20 nm sized, spherical shaped silver nanoparticles whereas gold nanoparticles showed many interesting morphologies with a size of 10-50 nm. The presence and binding of proteins with nanoparticles was confirmed by FTIR study. Interestingly, the myco derived silver nanoparticles exhibited superior antimicrobial activity than the standard antibiotic, streptomycin except against Staphylococcus aureus and Bacillus subtilis. The leakage of intracellular components such as protein and nucleic acid demonstrated that silver nanoparticles damage the bacterial cells by formation of pores, which affects membrane permeability and finally leads to cell death. Further, presence of nanoparticles in the bacterial membrane and the breakage of cell wall were also observed using SEM. Thus, the obtained results clearly reveal that these antimicrobial nanoparticles could be explored as promising candidates for a variety of biomedical and pharmaceutical applications.

As metal/metalloid exposure is inevitable owing to its omnipresence, it may exert toxicity in humans. Recent advances in metal/metalloid analysis have been made moving from flame atomic absorption spectrometry and electrothermal atomic absorption spectrometry to the multi-elemental inductively coupled plasma (ICP) techniques as ICP atomic emission spectrometry and ICP-MS. ICP-MS has now emerged as a major technique in inorganic analytical chemistry owing to its flexibility, high sensitivity and good reproducibility. This in depth review explores the ICP-MS metallic profile in human toxicology. It is now routinely used and of great importance, in clinical toxicology and forensic toxicology to explore biological matrices, specifically whole blood, plasma, urine, hair, nail, biopsy samples and tissues.

“…Despite being an overall mature technology, battery design and performance have changed drastically over the past decade with the development and implementation of nanomaterials [8,[11][12][13]. The nanoscale size reduction leads to enhancements of the Li-ion battery intercalation capability by increasing the specific surface area for interfacial Faradic reactions, improving the mass and charge diffusion paths, and modifying the surface thermodynamics which can facilitate phase transitions and eliminate miscibility gaps [14].…”

Lithium-ion batteries are a well-established technology that has seen steady gains in performance based on materials chemistry as well as microstructure design and assembly over the past several decades. There are many material selections available when designing and assembling the device such as electro-active species, additives, and particle size/morphology to name a few. Many of the research proclamations focusing on the advantages of nanosized electrodes have yet to find commercial application, and considerable improvements in energy density and stability are still necessary in order to achieve energy storage parity. Therefore, the design and use of kinetically stabilized nanostructures should be considered. Over the past several years, significant studies have been conducted examining the synthesis and performance of heterogeneous structures. While heterogeneous structures typically refer to the combination of two or more materials, in this case it refers to architectures displaying more than one size scale (i.e., micro/nano). A great deal of recent efforts have focused on the formation and understanding of nanoparticle superstructures with a vast range of architectures. The design of microstructurally composed nanoparticle assemblies would, for instance, possess the
