Paclitaxel delivery from cobalt-chromium alloy surfaces using self-assembled monolayers

Abstract

Polymer-based platforms in drug-eluting stents (DESs) can cause adverse reactions in patients. Hence, the development of a polymer-free drug delivery platform may reduce adverse reactions to DES. In this study, the use of a polymer-free platform, self-assembled monolayers (SAMs), is explored for delivering an antiproliferative drug [paclitaxel (PAT)] from a stent material [cobalt-chromium ((Co-Cr) alloy]. Initially, carboxylic acid terminated phosphonic acid SAMs were coated on Co-Cr alloy. Two different doses 25 and 100 μg/cm2) of PAT were coated on SAM coated Co-Cr surfaces using a microdrop deposition method. Also, control experiments were carried out to coat PAT directly on Co-Cr surfaces with no SAM modification. The PAT coated specimens were characterized using the Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and atomic force microscopy (AFM). FTIR spectra showed the successful deposition of PAT on SAM coated and control-Co-Cr surfaces. SEM images showed islands of high density PAT crystals on SAM coated surfaces, while low density PAT crystals were observed on control-Co-Cr alloy. AFM images showed molecular distribution of PAT on SAM coated as well as control-Co-Cr alloy surfaces. In vitro drug release studies showed that PAT was released from SAM coated Co-Cr surfaces in a biphasic manner (an initial burst release in first 7 days was followed by a slow release for up to 35 days), while the PAT was burst released from control-Co-Cr surfaces within 1–3 days. Thus, this study demonstrated the use of SAMs for delivering PAT from CouCr alloy surfaces for potential use in drug-eluting stents. ©2011 American Vacuum Society.
