CYTOTOXICITY OF COPPER NANOPARTICLES SYNTHESIZED USING DRIED GINGER | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 Copper nanoparticles are used in a wide range of fields, including medicine, agriculture, and engineering, to name a few. This biotechnology incorporates biological concepts of physical and chemical properties to create nano-sized particles with unusual properties. The quality of being harmful to cells is known as cytotoxicity. The goal of this study was to look at the cytotoxicity of copper nanoparticles made from dried ginger. Copper nanoparticles were synthesised using a green method and characterised using UV-VIS spectroscopy. The brine shrimp lethality assay was used to assess the cytotoxicity of the dried ginger induced copper nanoparticles at various concentrations. The findings showed that copper nanoparticles made from dried ginger had lower toxicity when used at lower concentrations. As a result, different nano-formulations of dried ginger mediated copper nanoparticles can be produced at optimal concentrations for safe and cost-effective therapeutics.

EVALUATION OF ANTIFUNGAL ACTIVITY AND CYTOTOXIC EFFECTS OF FRUIT MEDIATED ZINC OXIDE NANOPARTICLES | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

The aim of this research is to make zinc oxide nanoparticles from Punica granatum and Elettaria cardamomum, measure their antifungal activity against Candida albicans, and see how toxic they are.

Introduction: Zinc oxide nanoparticles are commonly used in medicine and science due to their inherent antimicrobial, antioxidant, and anti-inflammatory properties, as well as their low toxicity. The green synthesis of these nanoparticles is favoured because it is simple, relatively repeatable, cost-effective, and produces more stable, non-toxic materials.

Materials and Methods: Green zinc oxide nanoparticles were made from aqueous fruit extracts of P. granatum and E. cardamomum. UV spectroscopy and scanning electron microscopy were then used to determine the properties of nanoparticles. The agar well diffusion method was used to assess antifungal activity, and the brine shrimp lethality assay was used to assess cytotoxicity.

P. granatum and E. cardamomum extracts allowed the synthesis of stable zinc oxide nanoparticles, according to the findings. The nanoparticles thus produced were also found to have strong antifungal properties, with a zone of inhibition of 12mm for 50L, 22mm for 100L, and 24mm for 150L. In a lethality assay, 80 percent of live shrimp larvae were found in a nanoparticle concentration of 20-30 L. The cytotoxicity of the nanoparticles, on the other hand, needs to be investigated further. They may be integrated into various products in the future, such as toothpaste, mouthwash, and mouth paint, to promote their effect.

CYTOTOXIC EFFECT OF LYCOPENE INCORPORATED CHITOSAN NANOPARTICLES USING BRINE SHRIMP LETHALITY ASSAY | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

Background: In the past few years, there has been an increase in periodontal disorder, which can be due to different causes. The treatment modality, however, remains the same, which is to recognise the cause of the disease and remove the cause of the oral cavity to create a safe microenvironment to repair itself to its full ability. The use of nanotechnology has become increasingly common in different dentistry fields.

Aim: The research aims to test the cytotoxic impact of chitosan nanoparticles incorporated with lycopene using a brine shrimp lethality assay.

Materials and Methods: The analysis included the assessment of the ability of lycopene-integrated chitosan nanoparticles ranging from 5 (μl - microlitre) to 50 μl as an emerging dental nanomedicine at different concentrations. A primary level animal test on brine shrimps was performed using the standard brine shrimp lethality assay (BSLA) method in order to test its cytotoxicity.

Results: The analysis shows that the levels of cytotoxicity (calculated in relation to the BSLA mortality rates) are directly proportional to the nanoparticle concentration used. It was noted that in all concentrations except 50 μl, lycopene has comparatively low cytotoxic levels, chitosan has a high cytotoxic level of more than 5 μl and the nanoparticle compound also has a high cytotoxicity of 5 μl. Another result from the analysis is that as compared to the compound particle, the individual components of the nanoparticles exhibited much less toxicity.

Conclusion: The analysis showed that the nanoparticle compound exhibits minimal toxicity at concentrations below 5 microL, but substantial nanoparticle toxicity occurs at higher concentrations. This provides an insight into the drug's secure dosage calculations. To ensure its protection and clinical applications, further research is required.

CYTOTOXIC EFFECT OF GRAPE SEED MEDIATED ZINC OXIDE NANOPARTICLES USING BRINE SHRIMP LETHALITY ASSAY - In vitro STUDY | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

Background: Zinc oxide nanoparticles are a type of metal oxide nanoparticles with a band gap of 3.3 eV and excitation binding energy of 60 meV at room temperature. It has gained considerable attention due to its unique catalytic, antibacterial, antifungal, photochemical, UV-filtering, anti-inflammatory properties owing to its large surface area to volume ratio. Synthesis of metal and metal oxide nanoparticles through green routes and environmentally benign methods has been focused by researchers to avoid the use of toxic chemicals making the process and the final product eco-friendly and non-toxic in nature.

Aim: To assess the cytotoxic effect of grape seed mediated zinc oxide nanoparticles using brine shrimp lethality assay.

Materials and Methods: Plant extracts were collected and prepared for obtaining the grape seed extract. Zinc oxide nanoparticles were then synthesised in a methodological manner, followed by the assessment and characterisation of the zinc oxide nanoparticles. The zinc oxide nanoparticles powder was then prepared. Brine shrimp lethality assay was the test used to identify the cytotoxic activity of the grape seed mediated zinc oxide nanoparticles and the results were statistically analysed.

Results: Cytotoxic activity of zinc oxide nanoparticles was verified through several tests such as Brine shrimp assay. It was observed that the initial number of nauplius reduced in a negligible amount after one day and very little after three days in only certain concentrations of Zinc oxide nanoparticles.

Conclusion: The grape seed mediated zinc oxide nanoparticles thus show very less or negligible cytotoxic activity as the concentrations were increased and thus the zinc oxide nanoparticles are expected to be used in future for effective drug systems and in the future drug formulations.

Context: Plant-based nanoparticles are stated to be healthy and eco-friendly.

Objective: To classify the cytotoxic effect of copper oxide nanoparticles mediated by tamarind fruit pulp on brine shrimp shrimp

Materials and methods: 0.55 g of tamarind extract was combined with 100 ml of distilled water to obtain a transparent solution to which 0.318 g of copper sulphate was added and stored for nanoparticle synthesis in an orbital shaker. The absorbance was measured by UV-Visible Spectroscopy at regular intervals and centrifuged and stored after verifying the formation of the nanoparticles. A plate of 6 wells of Elisa was taken and filled with saline water and 10 brine shrimp nauplii were put with due care in each well. In each well, different volumes of nanoparticles starting from 5 μl to 25 μl were taken and the cytotoxicity was tested 24 hours later.

Results and Discussion: The number of nauplii brine shrimps was counted and all of the nauplii on the first day were alive. On day 2, only 9 nauplii were detected alive at 5 μL and 10 μL concentrations; 7 were detected alive at 15 μL and 20 μL concentrations; and 6 nauplii were detected alive at 25 μL concentrations. The overall cytotoxicity was observed at a concentration of 25μl. All the nauplii were alive in the control group without the copper nanoparticle controlled by tamarind.

Conclusion: The current research concludes that nanoparticles of copper oxide are healthy at low concentrations. After more in-vivo research, the dose dependent cytotoxicity found with tamarind-mediated copper nanoparticles may be used for use in cancer therapeutics.
