Revolutionary “Powder Spray” Stops Bleeding in Seconds, Opens Doors to Advanced Medical Treatments
A research team at Kyungpook National University (KNU) in South Korea has developed a groundbreaking powder-based bioadhesive that can halt bleeding within five seconds, even in wet environments. This innovation, utilizing ‘Bioorthogonal Click Chemistry,’ promises to transform emergency medicine and pave the way for advancements in drug delivery and cancer treatment.
The Problem with Existing Bleeding Control Methods
Traditional hemostatic agents, like fibrin and cyanoacrylate-based adhesives, often struggle to maintain effectiveness in the presence of blood or other bodily fluids. They can take significant time to solidify, hindering rapid response in critical situations. Some materials likewise present toxicity concerns or lack the necessary flexibility for use on delicate tissues.
How the KNU Bioadhesive Works
The KNU team’s bioadhesive is a powder composed of albumin, gelatin, and a specialized polymer called 4-arm PEG-DBCO. In its dry state, the powder remains inert. However, upon contact with moisture – such as blood – a rapid cross-linking reaction occurs within five seconds, forming a robust gel. This swift action provides immediate and effective bleeding control.
Beyond Hemostasis: A Multifunctional Medical Platform
This isn’t just about stopping bleeding. Researchers envision this powder as a versatile platform for various medical applications. By incorporating near-infrared responsive materials (ICG), the adhesive can be used in photothermal therapy (PTT) to selectively destroy residual cancer cells after surgery. Experiments have demonstrated that laser irradiation applied to the adhesive-covered cells generates heat, leading to cell death.
Potential for Implantable Devices
The adhesive’s properties also make it suitable for securing minor electronic chips (RFID) to organ surfaces. This opens possibilities for next-generation implantable medical devices and long-term monitoring solutions.
Successful Animal Trials and Biodegradability
Animal studies involving liver and gastrointestinal bleeding models showed immediate and potent hemostatic effects, with bleeding stopping in under five seconds. Importantly, the material naturally degrades within two weeks inside the body, eliminating the need for surgical removal.
From Lab to Market: Quickderm Takes Shape
Professor Lee Chang-kyu, the lead researcher, has founded a startup company, Quickderm, to commercialize the technology. The company has been selected for the Startup Growth Technology Development Program (D딤돌 R&D) by the Ministry of SMEs and Startups, providing funding for product development.
Future Trends and Implications
This development aligns with a growing trend towards bio-inspired materials and rapid-response medical technologies. The ability to create adhesives that function effectively in wet environments is crucial for a wide range of applications, from battlefield trauma care to surgical procedures. The multifunctional nature of this adhesive – combining hemostasis, drug delivery, and device anchoring – represents a significant step towards personalized and integrated medical solutions.
