Food forensics: Techniques for authenticity determination of food products.

The need for reliable and precise analytical techniques for food authentication and traceability has increased in recent decades due to the excessive competition for the production of competitive food products which leads to a high chance of food fraud. In this article, applications of several analytical techniques such as DNA-based techniques, spectrometric techniques, spectroscopic techniques, chromatographic techniques, lateral flow immunoassays, and neutron and proton based nuclear analytical techniques for forensic food analysis have been discussed. These sophisticated techniques are capable to analyze the food samples rapidly and permit the identification of specific parameters which are useful for investigations of food frauds in various legal issues.

Environmental perspective of COVID-19.

The outbreak of COVID-19 has caused concerns globally. On 30 January WHO has declared it as a global health emergency. The easy spread of this virus made people to wear a mask as precautionary route, use gloves and hand sanitizer on a daily basis that resulted in generation of a massive amount of medical wastes in the environment.

Nano-interfacial decoration of Halloysite Nanotubes for the development of antimicrobial nanocomposites.

In recent times, incorporation of Halloysite Nanotubes (HNTs) with various antimicrobial agents as interfacial materials between these nanotubes and pathogenic microorganisms, for the development of antimicrobial nanocomposites with enhanced antimicrobial activities has gained researcher's interest. The main benefits given by HNT to these nanocomposites include enhanced thermal and mechanical stability of the antimicrobial nanocomposites and also prolong durability and release of the antimicrobial agents in a sustained manner. The exceptional structure of these aluminosilicate minerals based nanotubes (hollow tubular lumen with huge surface area) and oppositely charged surface molecules assist in attaching various molecules on both, the internal surface as well as on the outer surface of these nanotubes.
