“…Most orthopedic implants are made of metallic alloys that are in general not ideal for this application because of possible release of metallic ions in the human body and encapsulation by fibrous tissue. Electrophoretic deposition of organic/inorganic composites on metallic alloys is being considered in order to modify the surface of metallic implants, both stainless steel and titanium alloys [6,8,10,12]. These composite coatings can induce osseointegration with host tissue and enhance the bulk and surface properties of the implants.…”

This study investigated the electrophoretic deposition (EPD) of the natural polymer zein combined with bioactive glass (BG) particles. Through the deposition of various BG compositions, namely 45S5 BG and Cu-doped BG, this work sought to demonstrate the ability of the films to potentiate the formation of hydroxyapatite (HA) in contact with simulated body fluid (SBF). Following incubation in SBF, the physical and chemical surface properties of the EPD films were evaluated using different characterization techniques. The formation of HA at the surface of the coatings following immersion in SBF was confirmed using Fourier transform infrared spectroscopy (FTIR). The results demonstrated HA formation in all coatings after seven days of immersion in SBF. Coating morphology and degradation of the zein films were characterized using environmental scanning electron microscopy (ESEM). The results confirmed EPD as a very convenient room temperature technique for production of ion releasing, bioactive, and antibacterial coatings for potential application in orthopedics.

Biopolymer coatings exhibit outstanding potential in various biomedical applications, due to their flexible functionalization. In this review, we have discussed the latest developments in biopolymer coatings on various substrates and nanoparticles for improved tissue engineering and drug delivery applications, and summarized the latest research advancements. Polymer coatings are used to modify surface properties to satisfy certain requirements or include additional functionalities for different biomedical applications. Additionally, polymer coatings with different inorganic ions may facilitate different functionalities, such as cell proliferation, tissue growth, repair, and delivery of biomolecules, such as growth factors, active molecules, antimicrobial agents, and drugs. This review primarily focuses on specific polymers for coating applications and different polymer coatings for increased functionalization. We aim to provide broad overview of latest developments in the various kind of biopolymer coatings for biomedical applications, in order to highlight the most important results in the literatures, and to offer a potential outline for impending progress and perspective. Some key polymer coatings were discussed in detail. Further, the use of polymer coatings on nanomaterials for biomedical applications has also been discussed, and the latest research results have been reported.

“…En las últimas décadas, la ingeniería de tejidos ha sido centro de atención de numerosas investigaciones, ya que proporciona un nuevo enfoque para el desarrollo de materiales capaces de contribuir a la reparación y regeneración de tejidos. Uno de los principales desafíos consiste en desarrollar materiales no tóxicos y con buena estabilidad mecánica al momento de su aplicación [1][2][3][4]. Entre los más estudiados se puede mencionar a los polímeros, cerámicos y biovidrios, fundamentalmente por su capacidad para ser reabsorbidos o degradados después de cierto tiempo de ser implantados, sin generar productos tóxicos en el organismo receptor [5][6][7][8].…”

RESUMEN En este trabajo se obtuvieron mediante co-deposición electroforética (co-EPD) dos clases de “recubrimientos blandos”. En todos los casos se empleó como fase inorgánica un biovidrio y como fase orgánica poli(ɛ-caprolactona), PCL, comercial (PCLC) o sintetizada aniónicamente y modificada con anhídrido maleico (PCLS). Para asegurar un adecuado recubrimiento del sustrato metálico se optimizaron variables del proceso de deposición (diferencia de potencial y tiempo). Mediante técnicas de caracterización complementarias (FTIR, DSC) se corroboró la presencia de ambas fases en los recubrimientos estudiados. En los recubrimientos con PCLC comercial se observó mediante SEM la formación de aglomerados de mayor tamaño en comparación a los recubrimientos con PCL aniónica (PCLS), observándose en ambos casos un alto grado de recubrimiento del sustrato metálico y la ausencia de microfisuras. La bioactividad de los recubrimientos obtenidos se evaluó mediante ensayos de inmersión en fluido corporal simulado (SBF). Por difracción de rayos X se evidenció la formación de un precipitado de hidroxiapatita sobre la superficie de los recubrimientos y a través de microanálisis SEM-EDS se determinó que la hidroxiapatita presente en los recubrimientos con PCLS funcionalizada presentó una relación calcio/fósforo Ca/P ~ 1,78; valor muy próximo al estequiométrico en tejidos óseos.
