Purpose: To make sure the biocompatibility and to get the permission to use the EPIRET3-device in a clinical trial according to German laws and to European ISO standards. To characterize the systems and the interaction with the retinal cells of RP-subjects after explantation. Methods: We tested the finally designed wireless epiretinal implants preclinically in vitro. The systems were directly s...

the purpose of this paper was to review the commercially available periodontal dressings, their physical and chemical properties, biocompatibility and therapeutic effects. electronic search of scientific papers from 1956 to 2012 was carried out using pubmed, scopus and wiley interscience search engines using the searched terms periodontal dressing, periodontal pack. numerous in vitro and in viv...

It is generally accepted that in vitro cell material interaction is a useful criterion in the evaluation of dental material biocompatibility. The objective of this study was to use 3D CLSM time lapse confocal imaging to assess the in vitro biocompatibility of dental composites. This method provides an accurate and sensitive indication of viable cell rate in contact with dental composite extract...

In this study, nanocellulose is isolated from oil palm empty fruit bunches using ultrafine grinding and ultrasonication. Here, nanocellulose, a reinforcing agent, mixed with polyvinyl alcohol sodium alginate, which act as the matrices. Nanocellulose-based fibers are produced via wet spinning method calcium chloride coagulant solvent. The effects of content on morphological, mechanical, in vitro...

As a metallic biomaterial, titanium (Ti) exhibits excellent biocompatibility, but its osteoinductivity is limited. Therefore, to improve this property, an electrophoretic deposition (EPD) technique was used coat the Ti surface with Ti3C2 MXene (Ti3C2), new class of two-dimensional nanomaterial. known have good biocompatibility and better than graphene oxide. The coating layer characterized by p...

PURPOSE Drug-eluting stents (DES) based on permanent polymeric coating matrices have been introduced to overcome the in stent restenosis associated with bare metal stents (BMS). A further step was the development of DES with biodegradable polymeric coatings to address the risk of thrombosis associated with first-generation DES. In this study we evaluate the biocompatibility of biodegradable pol...

The aim of the present work was to prepare and characterize biopolymer nanocarriers and evaluate their suitability in possible oral delivery of insulin. The egg albumin biopolymer was used to prepare nanoparticles which were further characterized by Fourier transformed Infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), zeta potential, Dynam...
