I am preparing a research proposal for the NIH. This document aims to develop a wearable, implantable, biocompatible, and battery-free device designed to continuously detect abnormal levels of endotoxins, a key biomarker in sepsis. The proposal envisions that the device will be in direct contact with the lesion, placed under the bandages. Its functionality would not only include the early detection of a potential nosocomial infection but also the localized administration of a drug to prevent complications. It is important to highlight that these types of infections often exhibit antibiotic resistance, making them a research priority for the National Institutes of Health (NIH). In this regard, we intend to submit our funding request to the following call:
