V swathi10dec1993@gmail.com Mary George marygeorge@stellamariscollege.edu.in <p>In the current scenario, Deep Eutectic Solvents (DESs) are persuasive greener solvents for the successful synthesis of different nanostructures due to their tunable properties with enhanced applications. We report here the successful formation of a nanocomposite based on cellulose and magnetite nanoparticles. The method of isolating cellulose from fruit shells of <em>Limonia acidissima </em>(L.) as detailed in the work is described for the first time. Magnetite nanoparticles were synthesized through the cost effective co-precipitation method and DES embracing choline chloride and fructose were used as non-toxic dispersant for the synthesis of cellulose-magnetite nanocomposite. Various physiochemical parameters like compositional, structural, morphological and magnetic properties are analyzed using FTIR, XRD, HRTEM, SAED and VSM techniques. Anticancer and antitubercular activities, performed by MTT and LRP assays respectively, reveals that the IC<sub>50 </sub>values for cellulose, magnetite and cellulose-magnetite nanocomposite are found to be 20.65 µg/ml, 44.66 µg/ml and 8.685 µg/ml and cellulose-magnetite nanocomposite shows 51.95% inhibition at 200 µg/ml concentration against <em>Mycobacterium tuberculosis</em>. The obtained results suggest that the prepared cellulose-magnetite nanocomposite can serve as a potential candidate for drug designing with the use of green solvents.</p> 2021-02-07T00:00:00+00:00 Copyright (c) 2021 ScienceIn Publishing https://pubs.thesciencein.org/journal/index.php/jmns/article/view/212 Significance of nanotechnology advances in food processing and packaging: consequences on human health 2021-02-21T09:16:27+00:00 Indu Nashier Gahlawat induingahlawat@gmail.com Manisha Wadhwa nee Dabas manisha.edu@gmail.com Poonam Lakra poonam03lakra@yahoo.com <p>Nanotechnology has revolutionized many scientific and industrial fields and has also made a good beginning in the food science and technology.

Chaudhary dr.m.p.chaudhary@gmail.com M.A. Shah shah@nitsri.ac.in <p>Recent advances in nanoscale technologies have provided advanced tools that can be easily used to trap, track, and manipulate individual nanoscale particles and viruses such as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and influenza viruses accurately. Among the promising strategies that exist to date, optical forces based techniques are the leading tools in this task. Perfectly, focused lasers act as “optical tweezers,” and can trap individual particles and viruses. These forces can be applied to study nanomaterials, viruses, the building blocks of a quantum computer, and collision processes occurring between molecules in a better way than ever before. These cutting-edge tools are capable of trapping, tracking, and manipulating at the nanoscale in three dimensions. The optical tweezers have been used within biological and nanotechnological fields for trapping, tracking, and manipulating nanoparticles, and viruses with high flexibility, precision, and integration. The outcomes are important breakthroughs in the field of molecular mechanics. Here, we review the state-of-the-art optical tools employed in optical trapping, tracking, and manipulation of different particles at the nanoscale. The trapping of nanoparticles down to single-digit nanometer range and individual SARS-CoV-2 are the main features discussed here. Optical tweezers are also capable of sizing and probing acoustic modes of a small virus such as SARS-CoV-2 and influenza. The optical tweezers can perform tracking of nanoparticles in three?dimensional with high?resolution by forwarding scattered light. Optical tweezers are used to grab single molecules and measure events that are occurring and employed for measuring forces and measuring distance. A miniature and modular system creates a reliable and mobile optical trap that has more potential to be applied in optical trapping technologies.</p> 2020-12-02T00:00:00+00:00 Copyright (c) 2020 ScienceIn https://pubs.thesciencein.org/journal/index.php/jmns/article/view/221 Mechanical and structural properties of aluminium nanocomposites reinforced with cerium oxide nanoparticles fabricated by powder metallurgy 2021-02-21T09:18:16+00:00 Naveen Kumar navi.singrauli@gmail.com Kumar Navin kumarnavinec10@gmail.com Richard J.
