A new strategy to improve osseointegration of implants is to stimulate adhesion of bone cells, bone matrix formation, and mineralization at the implant surface by modifying surface coating on the nanoscale level. Plant-derived pectins have been proposed as potential candidates for surface nanocoating of orthopedic and dental titanium implants due to 1) their osteogenic stimulation of osteoblast...

A layer-by-layer gelatin nanocoating is presented for use as a tunable, dual response biomaterial for the capture and release of circulating tumor cells (CTCs) from cancer patient blood. The entire nanocoating can be dissolved from the surface of microfluidic devices through biologically compatible temperature shifts. Alternatively, individual CTCs can be released through locally applied mechan...

A new fiber-optic pH sensor based on a thin-core fiber modal interferometer with electrostatic self-assembled nanocoating is presented. After inserting a segment of thin-core fiber into a standard single-mode fiber, high-order cladding modes are excited and interfere with the core mode to form an in-fiber modal interferometer. The side surface of the sensor is then deposited with poly(allylamin...

BACKGROUND Bioengineered plant-derived Rhamnogalacturonan-Is (RG-Is) from pectins are potential candidates for surface nanocoating of medical devices. It has recently been reported that RG-I nanocoatings may prevent bacterial infection and improve the biocompatibility of implants. The aim of the study was to evaluate in vitro impact of bioengineered RG-I nanocoatings on osteogenic capacity and ...

The main purpose of the research was to develop the micromodel of biocompatible titanium nitride nanocoating deposited on polymer by pulsed laser deposition method in blood chambers of Polish ventricular assist devices: POLVAD and POLVAD_EXT. The analysis of the parameters of micromodel crucial for the phenomenon of loss of cohesion occurring between coating and substrate was carried out as wel...

Fibrin plays an important role during wound healing and skin regeneration. It is often applied in clinical practice for treatment of skin injuries or as a component of skin substitutes. We prepared electrospun nanofibrous membranes made from poly(l-lactide) modified with a thin fibrin nanocoating. Fibrin surrounded the individual fibers in the membrane and also formed a thin fibrous mesh on sev...

Nanopaint is a new type of coating material that could offer significantly improved coating performance and/or a number of new functionalities, such as super scratch resistance, self-healing, surface texture alteration control, and toxic chemical/acid/corrosive agent repelling. However, how to ensure the achievement of the anticipated nanocoating performance and functionalities in coating manuf...

The paper presents a novel pressure sensor based on a silicon nitride (SiNx) nanocoated long-period grating (LPG). The high-temperature, radio-frequency plasma-enhanced chemical-vapor-deposited (RF PECVD) SiNx nanocoating was applied to tune the sensitivity of the LPG to the external refractive index. The technique allows for deposition of good quality, hard and wear-resistant nanofilms as requ...

Siamese orange fruit is very popular today, driven by the increasing public demand or healthy food. oranges contain bioactive phenolic compounds, carotenoids, vitamins, minerals, and fiber which are good for health. The weakness of their quality declines quickly short shelf life. Postharvest handling with application coatings from natural ingredients to extend life fruits currently needed reduc...

The atmospheric corrosion rate of materials changes based on different environmental conditions including time to be exposed to wet condition, relative humidity, surrounding temperature, and impurity of the air. The adhesive bond is relatively weak in conventional surface coating process which may lead the separation of these coatings and reduction of effective coating lifecycle. Some conventio...
