Researchers at the National University of Singapore (NUS) have developed dissolving microneedle patches that deliver living “biofertilizer” straight into plant tissue. In greenhouse tests, Choy Sum and Kale grew faster—by shoot biomass, leaf area and height—while using more than 15% less biofertilizer than standard soil inoculation.
