Since dental implants are used in contact with many different tissues, it is necessary to have optimum surface compatibility with the host bone tissues and soft tissues. Furthermore, dental implant surfaces exposed to the oral cavity must remain plaque-free. Such materials can be created under well-controlled conditions by modifying the surfaces of metals that contact those tissues. “Tissue-com...

The potential of terahertz pulsed imaging (TPI) to predict the dissolution performance in sustained-release tablets was investigated in this study. Batches of coated tablets with similar weight gain during the coating process at the lab and pilot scales were subjected to non-destructive imaging by TPI and subsequently analysed by dissolution testing. The results from the dissolution tests revea...

Magnetic microrobots and nanorobots can be remotely controlled to propel in complex biological fluids with high precision by using magnetic fields. Their potential for controlled navigation in hard-to-reach cavities of the human body makes them promising miniaturized robotic tools to diagnose and treat diseases in a minimally invasive manner. However, critical issues, such as motion tracking, b...

To develop a method that can maintain egg freshness during practical storage conditions, eggs were coated with chitosan and stored with or without dry ice. The physicochemical and microbiological qualities of eggs were evaluated during 14 d of storage at 4 and 23°C without dry ice and at 23°C with dry ice. The combination of chitosan coating and dry ice significantly inhibited a Haugh unit decr...

Isolated mitochondria are polymerically functionalized for transplantation into metabolically compromised cells. In article number 1700530, Elvin Blanco, Dale J. Hamilton, and co-workers demonstrate that coating mitochondria with a dextran-triphenylphosphonium (TPP) conjugate results in longer functional survival of the organelle ex vivo, increased cellular uptake, and an enhanced shift in the ...

Insect residue adhesion to moving surfaces such as turbine blades and aircraft not only causes surface contamination problems but also increases drag on these surfaces. Insect fouling during takeoff, climb and landing can result in increased drag and fuel consumption for aircraft with laminar-flow surfaces. Hence, certain topographical and chemical features of non-wettable surfaces need to be d...

Quantum dots (QD) nanoparticles have been widely used in biomedical and electronics fields, because of their novel optical properties. Consequently it confers enormous potential for human exposure and environmental release. To increase the biocompatibility of QDs, a variety of surface coatings or functional groups are added to increase their bioactivity and water solubility. Human adult low cal...

A multiple-unit formulation for time-dependent colonic release of insulin was obtained by coating insulin and sodium glycocholate immediate-release minitablets with: (i) Methocel® E50, a low-viscosity hydroxypropyl methylcellulose (inner coating), (ii) 5:1 w/w Eudragit® NE/Explotab® V17, a mixture of a neutral polymethacrylate with a pore-forming superdisintegrant (intermediate coating), and (i...

Atomically smooth graphene as a surface coating has potential to improve implant properties. This demonstrates a method for coating nitinol alloys with nanometer thick layers of graphene for applications as a stent material. Graphene was grown on copper substrates via chemical vapor deposition and then transferred onto nitinol substrates. In order to understand how the graphene coating could ch...

in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...
