The possibilities of using newly developed nano- and micro-thin films in biomedicine are intensively studied at the present time. Many research institutions are looking for ways to evaluate mechanical properties of these films. One of the most important and frequently studied characteristics is practical adhesion. A very important method for evaluating the practical adhesion strength is scratch...

Tissue adhesives have emerged as an alternative to sutures and staples for wound closure and reconnection of injured tissues after surgery or trauma. Owing to their convenience and effectiveness, these adhesives have received growing attention particularly in minimally invasive procedures. For safe and accurate applications, tissue adhesives should be detectable via clinical imaging modalities ...

It has been shown previously that peripheral nerve axons are regenerating through microvias in silicon devices. A major challenge is the design of a biocompatible integrated neural connector allowing simultaneous, multi-site recordings or stimulation of axons in nerve bundles and to establish a reliable mechanical and electrical connection. This paper describes on-going research in the framewor...

The significance of developing implantable, biocompatible, miniature power sources operated in a low current range has become manifest in recent years to meet the demands of the fast-growing market for biomedical microdevices. In this work, we focus on developing high-performance cathode material for biocompatible zinc/polymer batteries utilizing biofluids as electrolyte. Conductive polymers an...

The use of polymers in the modern pharmaceutical industry is quite wide and needs a lot of different information. One of the more recent applications is the impregnation of a polymeric system with a drug using as carrier a supercritical fluid. This process is based on dissolving the active principle in a supercritical fluid, the supercritical solvent swells and reduces the glass transition temp...

This paper was intended as a comparative study between the microstructural features of two water-ferrofluids intended for biological applications. In both cases the ferrophase was prepared by auto-catalytic reaction between ferrous and ferric salts resulted in magnetite and some maghemite precipitates. The difference is given by the stabilizer molecule: tetramethyl ammonium hydroxide and, respe...

The plasmonic properties of noble metal nanoparticles facilitate their use in novel in-vivo bio-applications such as targeted drug delivery and cancer cell therapy. Nanosilver is best suited for such applications as it has the lowest plasmonic losses among all such materials in the UVvisible spectrum. Its toxicity, however, can destroy the surrounding healthy tissue and thus, hinders its safe e...

Biocompatible macromolecular two-photon initiator based on hyaluronan

Purpose The leaves and flowering stem of Origanum vulgare contain essential oils, flavonoids, phenolic acids and anthocyanins. We propose a new, simple, one-pot, O. vulgare extract (OVE) mediated green synthesis method of biocompatible gold nanoparticles (AuNPs) possessing improved antioxidant, antimicrobial and plasmonic properties. Materials and methods Different concentrations of OVEs were...

This article describes the development of a method for a biocompatible sensor device for the intent of in-vivo breast tissue dielectric properties measurements. This article focuses on a specific type of sensor that utilizes an LC circuit with an inter-digital capacitor (IDC) with small size and high sensitivity for early stage breast cancer detection. To meet this objective an IDC was optimize...
