Metal sulfide nanoformulations and nanocomposites for seed priming and storage protection

Overview

This solution offers ecofriendly metal sulfide nanoformulations and nanocomposites designed for seed priming and seed storage protection. The technology addresses seed-borne fungal pathogens by disrupting fungal cell wall integrity and inducing cellular leakage, while simultaneously activating aquaporins to support germination. After performing their protective function, the nanomaterials degrade and are taken up by plants as nutrients, leaving zero residue in the soil.

The innovation is particularly relevant for seed storage applications where no commercial chemical treatments are currently recommended, providing a sustainable alternative for the agricultural sector.

Technical specifications

Core technology:

• Metal sulfide nanoformulations and nanocomposites derived from essential insoluble inorganic materials scaled down to nano size for antimicrobial activity
• Mechanism of action against fungi involves cell wall disruption and induction of cellular leakage
• Seed priming capability through activation of aquaporins, supporting water uptake and germination
• Self-degrading design that transitions from antimicrobial agent to plant nutrient after pathogen control
• Zero residue profile in soil following degradation

Key applications:

• Seed treatment and priming to improve germination rates
• Seed storage protection against storage fungi
• Sustainable crop protection where chemical alternatives are unavailable or undesirable
• Nutrient delivery through nanomaterial degradation products

Technology readiness level

The technology is currently at the research and validation stage. The research hypothesis is based on the principle that essential insoluble inorganic materials can be activated at the nano scale to target microbial cell walls while remaining compatible with plant biology. Further validation is needed to confirm efficacy across different seed types, storage conditions, and agricultural environments, as well as to optimize degradation timelines and nutrient uptake pathways.
