However, maintaining signal quality over time is complicated by inflammatory tissue responses and degradation of electrode materials. Organic electrode coatings offer a solution by enhancing recording and stimulation capabilities, including reduced impedance, increased charge injection capacity, and the ability to incorporate and release anti\u2010inflammatory drugs. Herein, acid\u2010functionalized multiwalled carbon nanotubes (CNTs) loaded with dexamethasone (Dex) are incorporated into poly(3,4\u2010ethylendioxythiophene) (PEDOT) as electrode coatings. The electrochemical stability and recording performance of the PEDOT\/CNT\/Dex coating over an extended period of \u224818\u2009months are investigated. Cyclic voltammetry (CV) stimulation is used to release Dex in half of the recording sites during the first 11\u2009days of implantation to reduce the acute inflammation. The PEDOT\/CNT\/Dex\u2010coated floating microelectrode arrays demonstrate stable in\u2009vivo electrode impedance and successful detection of visually evoked neural activity from the rat visual cortex even at chronic time points. Additionally, the CV\u2010stimulated sites exhibit higher single\u2010unit (SU) recording yield, amplitudes, and signal\u2010to\u2010noise ratio compared to unstimulated sites. These results highlight the potential of anti\u2010inflammatory treatments to improve the quality and longevity of chronic neural recordings.<\/jats:p>","DOI":"10.1002\/anbr.202400114","type":"journal-article","created":{"date-parts":[[2025,1,25]],"date-time":"2025-01-25T03:10:51Z","timestamp":1737774651000},"source":"Crossref","is-referenced-by-count":17,"title":["Long\u2010Term
