Nano-Biopesticide Delivery System for Sustainable Agricultural Pest Management
Eco-friendly nano-biopesticide (NBP) platform using plant-derived active compounds (Neem) embedded in biopolymer nanoparticles for targeted, controlled-release pest control. Designed to replace harsh chemical insecticides with reduced environmental accumulation, improved delivery efficiency, and enhanced stability of bio-active compounds during application.
Overview
This research proposes a Nano-Biopesticide (NBP) platform that delivers plant-derived bioactive compounds using biopolymer nanoparticles as a sustainable alternative to conventional chemical insecticides. The approach targets major agricultural pests by interfering with their chemical ecology, while addressing key limitations of traditional pesticide application such as environmental accumulation, off-target effects, and instability of natural active ingredients.
The solution focuses on encapsulating insecticidal molecules derived from the Neem tree (Azadirachta indica) within nano-scale biopolymer carriers. Neem seeds contain a range of bioactive compounds with proven insecticidal properties, but their practical deployment has been limited by stability challenges during field application. The nanoparticle delivery system is designed to protect these compounds, improve their adherence to target surfaces, and enable controlled release under specific environmental conditions, producing measurable pest-control results within hours while remaining non-hazardous to plants, animals, and humans.

Technology readiness level
This research is at an early conceptual stage. The team is seeking funding to initiate investigations and has not yet generated experimental data. Future validation plans include developing the nanoparticle delivery system, embedding Neem-derived bioactive compounds into biopolymer nanoparticles, and testing insecticidal efficacy and environmental safety. The approach is positioned as a sustainable, eco-friendly alternative to harsh chemical insecticides, with the potential to advance from laboratory validation to field trials as research progresses.
About The University of Adelaide
The University of Adelaide was a comprehensive public research university in South Australia, with a city‑centre campus and specialised sites linking teaching, research and translation. Co‑location within Adelaide BioMed City placed teams beside the Royal Adelaide Hospital and SAHMRI, enabling clinical trials, while AIML at Lot Fourteen linked researchers to an innovation district. At the Waite Research Precinct, co‑located partners and infrastructure such as the Plant Accelerator supported industry‑engaged R&D. Research was backed by national funding, including the Australian Research Council and NHMRC. On January 5, 2026 it merged with the University of South Australia to form Adelaide University; these assets now operate within the new institution with dedicated tech transfer support.
