ARROW ROOT MEDIATED SELENIUM NANOPARTICLE AND ITS CHARACTERIZATION | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

The purpose of the research is to synthesize the arrowroot-mediated selenium nanoparticles (SeNPs) and further define their characterization. With its applications in science and technology to create new stuff, the area of nanotechnology is increasingly growing. Today, as the marvel of medicine, nano items are named. Globally, the development of SeNPs is now emerging.

The characterisation of nanoparticles deals with the characterisation of the nanoparticles' physical and chemical properties. Selenium nanoparticles are synthesized and characterized by transmission electron microscopy and UV-vis spectroscopy using Arrowroot. As the shape is rod-shaped and the scale is 200 nm, the effects are observed. Therefore, the nanosized nanoparticles mediated by arrowroot have many applications in modern technology and have high medicinal value as well.

PREPARATION OF MOUTHWASH USING LYCOPENE - CHITOSAN NANOCOMPOSITE AND ITS CYTOTOXIC AND ANTIMICROBIAL PROPERTIES - AN In vitro STUDY | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 Background: Application of chitosan in dentifrices or mouthwash is limited, several studies have shown that it is extremely effective in destroying bacteria as well as reducing plaque film and gingivitis. Lycopene can function as a potent scavenger of Hypochlorous acid at a wide range of concentration that may span various pathophysiological and supplemental ranges. Therefore combining both using nanotechnology would be beneficial for the exploitation of new generations of antimicrobial agents and for the development of new biomedicine.

Aim: The study aims to prepare lycopene mediated chitosan based mouthwash and to assess its antimicrobial and cytotoxic effects.

Materials and Methods: The study involved the preparation of lycopene mediated chitosan based mouthwash from their extracts. Assessment of cytotoxic and antimicrobial effects of mouthwash was done. In order to test its cytotoxicity a primary level animal testing on brine shrimps was conducted using the standard brine shrimp lethality assay (BSLA) method and agar diffusion method was used to assess its antimicrobial properties.

Results: The study reveals that the mouthwash prepared had better antimicrobial properties while evaluating it by agar diffusion methods and cytotoxicity levels which were calculated in relation to the mortality rates of the BSLA are directly proportional to the concentration of the nanoparticle used. This gives an insight into the safety and drug dosage levels.

Conclusion: The study can be concluded that the lycopene mediated chitosan based mouthwash being studied shows great potential in the field of dentistry. Cytotoxicity levels of the mouthwash exhibits acceptable toxicity at concentrations below 10 μL however at higher concentrations it shows a significant toxicity and also showed better antimicrobial properties as the zone of inhibition (ZOI) increased with the concentration of lycopene mediated chitosan based mouthwash.
