An electrostimulation cell device with patterned TiO2: Nb thin films as bio-electrodes

Jobin M., Pellodi C., Sandu C., Benvenutti G., Sandoz A., Stoppini L., hepia / HES-SO University of Applied Sciences of Western Switzerland, CH

We present a cellular test device based on Nb:TiO2 (niobium dooped titania) transparent conductive oxide (TCO) as bio-electrodes. The device is intended to easily provide electrical stimuli to a given cell tissue and to monitor [...]

Apparent Tissue Modulus for Micro/Nano Pillar Arrays

Rajhi A.A., Coulter J.P., Jedlicka S.S., Lehigh univeristy, US

Polymeric culture platforms with micro/nano topographies have provided a powerful approach to modulate cell to substrate interactions. Cells respond to chemical and mechanical signals from surrounding microenvironments. While chemical signals have been well studied in [...]

Biogelx: Designer Gels for Cell Culture

Lopez-Bernardo E., Irvine E., Ulijn R., Lightbody D., Biogelx, US

Biogelx Limited is a biomaterials company that designs tuneable peptide hydrogels, offering artificial tissue environments to cell biologists for a range of cell culture applications. The hydrogels are highly tunable, cell-matched biomaterials, capable of revolutionizing [...]

Analysis of Stem Cell Culture Performance in a Microcarrier Bioreactor System

Ponnuru K., Wu J., Ashok P., Tzanakakis E.S., Furlani E.P., SUNY-Buffalo, US

Human pluripotent stem cells (hPSCs) are capable of differentiating into all somatic cell types and hold great potential for future clinical applications. Recent studies on cell culture in stirred tank bioreactors indicate that mechanical forces [...]

Vertically Aligned Patterned Peptide Nano Wires for Cellular Studies

Taskin M.B., Technical University of Denmark, DK

Over the years, scientific studies have shown that one crucial point when designing biological platforms is the strict environmental conditions required for cell and tissue culturing, such as pH, temperature, medium content and other parameters [...]

Cell adhesion behaviors on polyethylene terephthalate surface modified by surface-wave plasma-initiated graft polymerization

Nina A., Ishizaki T., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

For better performance in biomedical applications, the PET surface still needs to be improved by functionalization, particularly controlling the hydrophilicity. In order to impart hydrophilicity to the PET surface, we tried to introduce acrylic acid [...]

Nano-Surface Behavior of Osteoblast Cell-Cultured Ti-30(Nb,Ta) with Low Elastic Modulus

Choe H.C., Ko Y.M., Brantley W., Chosun University, KR

Ti and Ti-alloys have good biocompatibility, appropriate mechanical properties and excellent corrosion resistance. However, the widely used Ti-6Al-4V is found to release toxic ions (Al and V) into the body, leading to undesirable long-term effects. [...]
