New Detection Method for Snake Venom
Researchers at The University of Warwick have introduced the first synthetic sugar detection test for snake venom, marking a significant advancement in rapid diagnosis and treatment options for snakebites. Every five minutes, approximately 50 individuals are bitten by snakes globally; of these, four may suffer permanent disabilities, and one may die. Rapid identification of snake venom is crucial for effective treatment in time-sensitive situations.
Traditional methodologies for diagnosing and treating snake venom primarily rely on antibody-based approaches, which often present challenges such as high costs, lengthy processing times, and varying results. The newly developed test, published in the journal ACS Biomacromolecules, provides a low-cost and efficient alternative. This innovative glycopolymer-based ultraviolet-visible (UV-vis) test specifically detects the venom of the Western Diamondback Rattlesnake (Crotalus atrox).
Dr. Alex Baker, the lead researcher from the Baker Humanitarian Chemistry Group, remarked on the complexity of snake venoms and the critical need for effective detection methods. The newly designed assay utilizes synthetic sugars that mimic natural sugar receptors in human bodies. This method, combined with an amplification system, makes it possible to visualize the results quickly. The assay aims to improve patient outcomes by enhancing the speed and accuracy of snake venom detection.
Snake venom has evolved to bind to specific sugar molecules on cell surfaces, disrupting essential biological processes like blood clotting. The research team engineered synthetic sugar chains attached to gold nanoparticles, which facilitated a visible color change when venom toxins adhered to the synthetic sugars. This approach not only provides a quick and reliable detection method but also allows for custom modifications to accommodate various snake venoms.
Mahdi Hezwani, the first author of the research, highlighted the assay’s potential to distinguish between different snake venoms based on their unique sugar-binding properties. In tests, venom from the Indian Cobra did not interact with the synthetic glycans used for Crotalus atrox, confirming the assay’s specificity.
This synthetic sugar detection test showcases the promising capabilities of the Warwick research team’s glyconanoparticle platform, previously utilized in COVID-19 detection. Compared to conventional antibody assays, this new method is faster, cheaper, and simpler to store. It offers a customizable approach, where synthetic sugars can be tailored to target specific toxins.
The research aligns with The University of Warwick’s initiative—STEM Connect—which aims to foster innovative solutions in science, technology, engineering, and mathematics. The full research paper is accessible for those interested in exploring the detailed findings.
