Janus microcapsule fertilizer coating with dual stimulus-responsive release
A novel Janus microcapsule coating platform for slow-release fertilizers, engineered with asymmetric hemispheres to optimize nutrient delivery. The system synchronizes nitrogen availability with plant uptake using dual stimuli of soil moisture and temperature, improving efficiency and reducing volatilization.
Overview
The Janus microcapsule fertilizer coating is an innovative solution designed to enhance nutrient delivery efficiency in agricultural applications. The platform employs a unique dual hemispherical design with one hydrophilic face directed towards the soil, while a hydrophobic face reduces nitrogen volatilization. This design allows the fertilizer to release nutrients in response to soil moisture and temperature, ensuring that nitrogen is available precisely when plants need it the most. The solvent-free system is environmentally friendly, using bio-compatible crosslinkers, and integrates seamlessly with existing fertilizer production lines.
Technical specifications
Key features:
- Asymmetric Janus microcapsule design with hydrophilic and hydrophobic faces
- Synthesized using microfluidic emulsion processing for precise control over capsule morphology

- Suitable for use with various substrates like urea, MAP, potassium sulfate, poultry litter, and blood meal
Technology readiness level
This technology is at TRL 3, with bench-scale development planned to optimize microcapsule synthesis and characterize release behavior. The upcoming phases will focus on formulation optimization and pilot-scale production readiness.
About Vuronyx Technologies
Vuronyx Technologies is an early-stage startup focused on commercialization of novel material science–based technologies and products, including water desalination, carbon fiber composites, advanced coatings, and rapid testing/prototyping. On its website, the company describes investigating a capacitive deionization (CDI) approach for selective, efficient salt removal from brackish water and industrial wastewater. It also describes work on carbon fiber composites for U.S. military and civilian applications, novel advanced-material coatings (including biobased resins, nanomaterials, and functionalized polymers), and toolkits/processes for rapid testing and prototyping (including field detection of narcotics). The company states it leases wet laboratory space in Woburn, Massachusetts, and collaborates with private enterprises and federal agencies, leveraging resources and facilities at institutions in Cambridge and Boston.
Public records and the company’s own updates also describe federal R&D funding and collaborations. The company’s site lists multiple SBIR awards (e.g., for radiation shielding coatings, water disinfection protocols, and manufacturing/scale-up work for MAX powders) and notes technology transfer activities such as selling its water desalination technology. External federal-award listing pages identify Vuronyx Technologies LLC (UEI LG4DM78DP641; headquartered in Woburn, MA) and characterize its business as material-science-based technologies with practical applications and commercial value.
