Evaluation of F127 / chitosan hydrogel as a scaffold for bone repair

Yang M.-C., Lai W.-F., Taiwan University of Science & Technology/Taipei Medical University, TW

An in situ gelled scaffold for bone tissue engineering to restore the function of bone tissues is developed. The gel is comprised of Pluronic F127 and chitosan. The gelation temperature (Tgel), and viscoelastic properties and [...]

Biomimetic Biphasic Nanocomposite Scaffold for Osteochondral Regeneration

Castro N.J., O’Brien C., Zhang L.G., The George Washington University, US

The current work focused on the development and evaluation of a novel biomimetic biphasic nanocomposite scaffold for osteochondral interfacial tissue engineering. Tissue-specific growth factor-encapsulated nanospheres were manufactured via a wet electrospray technique and incorporated within [...]

Aerosol-based fabrication of modified chitosans and their application for gene transfection

Byeon J.H., Roberts J.T., Purdue University, US

Droplets containing modified chitosans were formed by collison atomization, dried to form solid particles, and collected and studied for potential use as nanocarriers (Figure 1). Modified chitosans consisted of a chitosan backbone and an additional [...]

Superhydrophobic and Superhydrophilic Nanocomposite Coatings for Preventing Microbial Adhesion on Liquid Food Contact Surface

Rungraeng N., Yoon S-H, Song W., Jun S., University of Hawaii at Manoa, US

Pathogenic microbes in biofilm matrix increase the potential of cross-contamination with processed food products, subsequently resulting in food borne disease outbreaks. Prevention of bacterial adhesion on food contact surfaces will have a massive impact in [...]

Grow of stem cells on chemical-laser generated titanium cobalt shape memory alloy nanoparticles

Karami A., Materials and Energy Research Centre, IR

In this research nanoparticles are fabricated using a method that is a combination of chemical and femtosecond laser ablation methods. The resulting nanoparticles are used to coat glass substrates in order to test the biocompatibility [...]

A novel technique using SWCNTs to enhanced development and root growth of fig plants (Ficus carica)

Flores D., Chaves J.S., Chacón R., Schmidt A., Instituto Tecnologico de Costa Rica, CR

The overall goal of this project is to look at possible mechanisms to explain the effects of SWCNTs in plant growth and its antimicrobial properties in order to reduce the use of harmful chemicals in [...]

Competitive Binding of Natural Amphiphiles to Graphene derivatives

Radic S., Geitner N., Podila R., Ke P.C., Ding F., Clemson University, US

Understanding the interaction between graphene derivatives and natural amphiphiles in biological and environmental milieu is important for the biosustainability and biocompatibility of graphene nanotechonology. Using rapid discrete molecular dynamics simulations, we systematically studied the binding [...]

Live Cell Membrane in Interaction with Antimicrobial Molecules

Lahiji R., Holl M.B., University of Michigan, US

Molecules in the nano size scale are potentially useful as therapeutic agents due to their size since they can interact in a sophisticated way at the cellular level. Antimicrobial oligomers (AMOs) are unique as they [...]

Water-borne Polymeric Nanoparticles for Glutathione-Mediated Intracellular Delivery of Anticancer Drugs

Grimaldi N., università degli studi di palermo, IT

A new family of water-borne, biocompatible and carboxyl-functionalized nanogels (NGs) was developed for glutathione-mediated delivery of anticancer drugs. Nanogels were generated by e-beam irradiation of aqueous solutions of a crosslinkable polymer. Molecular structure and topology [...]

In vivo nanotoxicology: Toxicoproteomics

Sabella S., Kote S., Pompa P.P., Italian Institute of Technology, IT

Proteomics applied to nanotechnology is now emerging as an attractive tool to address the still unanswered questions dealing with nano-biointeractions and NPs-induced toxicity in living systems. The unique advantage provided by “omic” techniques (such as, [...]
