We are delighted to share that a research article from the Department of Life Sciences, has been published in the international journal 3 Biotech (Springer, 2025).

The study, titled “Green Synthesis of Cymodocea serrulata Zinc Oxide Nanoparticles for Sustainable Antibacterial, and Mosquito Control and their Toxicity to Non-target Organisms”, was co-authored by Dr. Paramasivam Deepak and his research team, in collaboration with national and international scientists.

Highlights of the Research

  • Eco-friendly Nanoparticles: The team synthesized zinc oxide nanoparticles (ZnO NPs) using extracts of Cymodocea serrulata, a marine seagrass.
  • Mosquito Control Potential: The nanoparticles showed remarkable toxicity against Aedes aegypti, Culex quinquefasciatus, and Anopheles stephensi – the vectors of dengue, malaria, and filariasis.
  • Antibacterial Properties: Strong activity was demonstrated against bacterial pathogens such as Pseudomonas otitidis and Enterococcus faecalis.
  • Safe to the Environment: Toxicity tests confirmed that these nanoparticles are non-harmful to non-target organisms like zebrafish embryos (Danio rerio) and brine shrimp (Artemia salina).

Why This Matters

Mosquito-borne diseases remain one of the most pressing public health issues worldwide. Chemical insecticides, while effective, often cause environmental damage and resistance in pests. This study provides a sustainable and nature-inspired solution, aligning with Kristu Jayanti University’s vision for impactful and eco-conscious research.
