Current Research Interests

  • Monitoring wound severity and healing through enzymatic electrochemical sensing. This research envisions continuous monitoring of wound healing on a wearable platform to enable personalized wound therapy through detection of specific biomolecules from injured tissue vicinity. The study investigates the biochemistry of analytes and purine precursors for detecting wound severity. Enzymatic electrochemical sensing protocols are utilized to detect such biomarkers, which offer a correlation with the healing progress of wounds. Different nanomaterials are explored in the study to obtain enhanced sensing performance. Techniques involved, explore polymers and soft biomaterials which can play a role in stable biomarker detection from wound milieu. This aids the design of a miniaturized and cost-effective wound-care sensor; and evaluation of its success on a wearable, healing platform. Non-invasive approaches in detection could facilitate convenient therapy in wound diagnostics and assist in taking medical decisions through the healing phases as and when necessary. This shall allow for efficient and effective wound management, enabling early treatment through therapeutic interventions before chronic tissue damage; and in turn reduce repeated trips to clinics, lowering the huge socio-economic costs associated with wound care.
