Integration of Living Cells with Silicon Microstructures for MEMS Applications

Molnar P., Bhargava N., Das M., Natarajan A., Wilson K., Hickman J.J., University of Central Florida, US

For many years biological and silicon-based structures were considered incompatible because of the difficulties to engineer an effective interface connecting the two systems. Recent developments in surface chemistry, bioengineering and cell biology enabled the creation [...]

Diffusion of Nanoparticles through the Tissues in Experiment

Reshetov I.V., Frank G.A., Sukharev S.S., Efremov G.D., Danileico Yu.C., Timoshenko V.Yu., P.A.Hertzen Moscow Research Oncological Institute (MROI), RU

We have created nanocrystals of silicon with sizes in the greatest measurement in the average 50 nm (from 4 to 100 nm), and nanocrystals of the oxide of aluminum with the adsorbed molecules of phthalocyanines, [...]

Nanotopography-controlled Cell Life and Death

Huang G.S., Su C-W, National Chiao Tung University, TW

NIH-3T3 cells were grown on nanodot arrays to investigate how cells respond to nanolandscape. The nanodot arrays consisted nanodot of diameters ranging from 10 to 200 nm which were fabricated by AAO processing on Ta-coated [...]

Effects of Zr Content on the Electrochemical Characteristics of Nano-Structure Controlled Ti-alloys

Oh M.Y., Choe H.C., Ko Y.M., Park S-J, Brantley W., Chosun University, KR

Objective: Pure Ti as well as Ti-6Al-4V alloy exhibit excellent properties for dental implant applications. However, for a better biocompatibility it seems important to avoid in the composition the presence of V due to the [...]

Mechanical Properties of Nano-Structure Controlled Ti-Hf Alloy for Dental Implant

Jeong Y.H., Choe H.C., Ko Y.M., Park S-J, Kim D.K., Brantley W., Chosun University, KR

Objectives: Cp-Ti has a excellent biocompatibility. So, it was widely used dental implants and artificial joint. But it is not strong enough for some dental applications. Since Hf belongs to the same group as Ti [...]

Nanocomposites for Restorative Dentistry

Uveges A., Bukovinszki K., Szaloki M., Hegedus C., Borbely J., University of Debrecen, HU

Dental filling materials are crosslinked resins with high abrasion resistance. Inorganic micro and recently nanofillers are introduced to improve their properties. However, the shrinkage of the resin component during the polymerization reaction is still a [...]

Nanodiamonds for Detoxification

Gibson N., Fitzgerald Z., Luo T.-J., Shenderova O., Grichko V., Bondar V., Puzur A., Brenner D., North Carolina State University, US

Our research deals with using nanodiamond particles as an enterosorbent to remove mycotoxins from the gastrointestinal tract. We are working on developing an ideal enterosorbent by obtaining appropriate size nanoparticles, modify nanodiamond surface groups, and [...]
