Researchers at North Carolina A&T State University in Greensboro have filed a provisional patent for Woundra, a plant-based wound dressing. The team also secured a $25,000 grant from NCInnovation to support the development of these cellulose-based hydrogels.
Why it matters
The development aims to provide reliable wound care for individuals in rural or farming communities who may lack immediate access to medical facilities. By integrating natural ingredients like Manuka honey and chitosan, the product offers a accessible alternative for wound management.
The researchers engineered cellulose-based hydrogels incorporated with polyvinyl alcohol to increase structural strength and flexibility. The design utilizes a combination of Manuka honey and chitosan to manage moisture and release antimicrobial treatments.
The players
North Carolina A&T State University
A public, historically Black research university located in Greensboro, North Carolina.
NCInnovation
An organization that supports applied research and commercialization efforts within the state of North Carolina.
Anthro Ventures
A firm that assists organizations in navigating complex federal regulatory landscapes.
EcoTrust
A collaborative partner working to develop efficient and cost-effective manufacturing methods.
The details
The research team partnered with EcoTrust to create low-cost manufacturing processes, with further regulatory guidance provided by Anthro Ventures. The product will eventually be available in multiple formats, including patches, foams, and ointments.
Timeline
9 to 15 months: Expected release of the over-the-counter hydrogel product.
35 months: Estimated total time for the FDA Class II medical device approval process.
The Big Picture
This project highlights the practical commercial output emerging from the North Carolina A&T State University agricultural and bioengineering research programs. It illustrates how university-led innovation is increasingly bridging the gap between laboratory science and rural healthcare delivery.
The potential commercialization of these dressings could provide residents with easier access to advanced antimicrobial wound care at home. If successfully brought to market, the product offers a lower-cost option for basic medical treatment outside of traditional clinics.
The takeaway
This development marks a significant step in using bio-based materials to address accessibility gaps in medical care. Readers should monitor for future regulatory updates as the team works toward clearing the FDA approval process.
