Publication details: Dervisevic, M., and Voelcker, N.H., Microneedles with Recessed Microcavities for Electrochemical Sensing in Dermal Interstitial Fluid. ACS Materials Letters 5 (2023) 1851-1858. https://doi.org/10.1021/acsmaterialslett.3c00441

This study presents an innovative method for creating a microneedle array that enhances biosensing performance by protecting the sensing layer during the insertion and removal of the biosensing patch. The method involves creating recessed microcavities on the microneedle surface, which are micro-pockets located at the tip of the microneedle.

These microcavities have multiple benefits, such as accommodating the sensing layer for electrochemical analyses, protecting the sensing layer during skin insertion and removal, positioning the sensing layer for easy interstitial fluid access, and preventing interference from other body fluids. This work aims to pave the way for a new era of microneedle-based biosensing technology through surface engineering, with the goal of developing clinically adequate transdermal sensing devices.

As the first author, Muamer Dervisevic co-led and conceptualized this project and was in charge of methodology, validation, investigation, data curation, formal analysis, and visualization of the work, as well as drafting and editing the manuscript.
