This review highlights the overview of recent trends in the usage of drugs as corrosion inhibitor for metal/alloy surfaces, particularly mild steel, aluminum, and copper in acidic, basic, or saline medium. The drug molecules generally containing atom having lone pair of electrons such as nitrogen (N), oxygen (O), Sulphur (S) and phosphorus (P) as well as a hydrophobic moiety that will repel aqueous corrosive species away from the metal surface and a mediately with an aromatic ring, unsaturation that are observed to be a significant component of extremely efficient inhibitors. The efficacy of various drugs, including antipyretics, analgesics, antibiotics, anti-depressants, and anti-histamines, is studied using weight loss, electrochemical impedance spectroscopy, potentiodynamic polarization and surface analysis techniques. Drugs molecules work by producing a layer on the metal's surface and can serve as anodic, cathodic, or mixed inhibitors. This protective film formed results of strong interactions such as free- orbital adsorption, chemisorption, and electrostatic adsorption, which prevent corrosive species from attacking the metal surface. Recent concerns and future prospective for further research and development to achieve more efficient and environmentally friendly inhibitors are additionally highlighted.

Nanoparticles (NPs) are strong colloidal particles with diameters ranging from 1nm–100 nm. They comprise of macromolecular materials and can be utilized therapeutically as adjuvant in immunizations or as medication transporters. In this paper two fundamental sorts of nanoparticles are discussed i.e., metallic nanoparticle and polymeric nanoparticle. Metallic nanoparticle is nano-sized metals with measurements (length, width, thickness) inside the size range of 1nm - 100nm. The properties, advantages, disadvantages and characteristics of metal nanomaterials are discussed in brief in this review. Polymers are the most common materials for constructing nanoparticle-based drug carriers. Polymers used to form nanoparticles can be both synthetic and natural polymers. This review summarizes the synthesis and fabrication of nanomaterials. It describes about synthesis of metallic and polymeric nanomaterials as well as synthesis of quantum dots. It gives insights of fabrication of nanomaterials. Applications of nanomaterials are also included in this review mainly focusing on biosensor, gas sensor, wastewater treatment and environmental applications. The tunable surface and optical properties of nanomaterials make the perfect contender for biosensing including the analysis of ailments, cellular imaging of cancerous cell and so on. Gas sensors have been utilized in numerous applications like monitoring the oxygen content in fuel mixture, observing food decay, health monitoring etc. Nanomaterials offer the potential for the productive expulsion of pollutants and biological contaminants thus extremely valuable in environment and wastewater treatment. Nanomaterials are highly recommended in future for these properties, mainly for their use in healthcare sector.

In current pandemic, as there is no approved specific antiviral agent for coronavirus disease (COVID-19) available till to date; Indian Ayurveda has emerged out as effective tool to control the prevailing pandemic at initial stage mainly by gearing up the immune system. Convalescent plasma therapy (CPT) has shown a glimpse of hope and some case study supported the hypothesis that CPT could be a prospective treatment option. The current study reported first time on a real time case study in India along with the outcome that CPT could be potentially improved the treatment of severe COVID-19. The CPT results presented here have shown that clinical symptoms were significantly improved along with increase of oxyhemoglobin saturation, also increased lymphocytes count whereas decreased C-reactive proteins within 3 days without any severe adverse side effect.
