2025 1209 Microneedles for plant growth 3

Caption

The microneedle patches are made using polyvinyl alcohol (PVA), a biodegradable, low-cost polymer, and infused with a plant growth-promoting rhizobacteria (PGPR) cocktail of Streptomyces and Agromyces-Bacillus. A 1 cm by 1 cm microneedle patch (shown in the petri dish on the right) carries a 40 by 40 array of 140-μm pyramids for application on leaves, while a short row of roughly 430-μm needles (shown in the petri dish on the left) suits thicker stems.
