Microneedles (MNs) form a safe and non-invasive drug-delivery platform for topic and systemic applications. Biocompatibility, easy application, improved efficiency-controlled release, and low concentrations needed are among the main benefits of the technology. Technologies based on MNs can increase the population's access to cutting-edge therapies through reduced costs and increase the well-being, successful diagnosis, prognosis, and consequent treatment adherence of patients with chronic diseases due to reduced pain, increased comfort, and reduced side effects. Recent studies from members of this consortium showed how the mechanical properties of polymeric MNs affect the release, improving penetration and flow of hydrophilic drugs for topical use1. We propose to explore this technology by developing novel transdermal delivery and biosensing tools for healthcare applications. We plan to use polymeric MN systems combined with monoclonal antibodies to validate: (1) Transdermal delivery tools for skin cancer therapy, vaccine delivery using monoclonal antibodies, and targeted therapies for psoriasis; (2) Transdermal biosensing tools to detect biomarkers for prognostic and diagnostic of psoriasis and infectious diseases via the construction of electrochemical lateral flow assay MN-sensor systems. In this consortium, we propose to explore different blends of polymers to create customized constructions of MNs as innovative treatment approaches for healthcare applications. (AU)
