Nanoskin Bacterial cellulose structured- Towards the development of regenerative medicine

Olyveira G.M., Costa L.M.M., Basmaji P., UFABC, BR

Bacterial cellulose (BC) has established to be a remarkably versatile biomaterial and can be used in wide variety of applied scientific endeavors, especially for medical devices. In fact, biomedical devices recently have gained a significant [...]

Synthesis and Characterization of Anti-CD4 monoclonal antibody-conjugated Magnetic Poly (glycidyl methacrylate) Particles and their Application on CD4+ Lymphocyte Separation

Pimpha N., Chaleawlert-umpon S., Chruewkamlow N., Kasinrerk W., National Nanotechnology Center, TH

To develop an efficient magnetic system for separation of CD4+ lymphocytes, we design a simple, specific, and cost-effective CD4 separation system without the need for column separation technique. Novel immunomagnetic particles have been prepared for [...]

Antioxidant activity of fullerene C60 against OH free radicals: A Quantum Chemistry and Computational Kinetics Study

Iuga C., Universidad Autónoma Metropolitana, MX

Fullerenes are considered to be the world’s most efficient radical scavenger, and represents an attractive tool for biological applications. Indeed, it have been demonstrated in vivo and in vitro, that fullerenes and related structures reduce [...]

Three-dimensional cell instructive scaffolds to direct stem cell fate

Viswanathan P., Chirasatitsin S., Reilly G., Engler A., Battaglia G., University of Sheffield, UK

Novel biomaterials design rarely incorporates the range of topographical (10nm – 100um) and chemical cues required to influence cell behaviour. Of particular interest is controlling human mesenchymal and embryonic stem cell fate. Recently it has [...]

Titanium Tungsten Coatings for Bioelectrochemical Applications

Wierzbicki R., Amato L., Lopacinska J., Heiskanen A., Emneus J., Boggild P., Molhave K., DTU Nanotech, DK

Our research interest is the combination of carbon nanotube electrochemistry with nanostructured substrates capable of cell scaffolding. Therefore, an adhesion / electric connection coating with good biocompatibility, PECVD compatibility and electrochemical stability needs to be [...]

Preparation, Characterization and Antioxidative Activity of Anti-aging Nanoemulsion and Lipid Nanoparticls

Xia Q., Wang H., Wang J., Tang J., Wang H., Wang J., Southeast University, CN

Nanoemulsions (NEs) and lipid nanoparticles (LNs) were regarded as suitable nanosized carriers of water-insoluble active components. These nanosized carriers could be used to load with drugs, nutrients and cosmetic actives and provide the appropriate application [...]

Starch/MWCNT/Epoxy Composites for Biodegradable Batteries

Ansari M.N.M., Shanks R.A., Kong I., Universiti Tenaga Nasional, MY

Currently, the vast majority of plastics are made from petroleum-based synthetic polymers that do not degrade in a natural environment and their disposal poses a serious problem. An environmentally-conscious alternative is to design polymer nanocomposites [...]

Poly(Lactic Acid) Hemp Composites Combined with Nano-Silica

Mustapa I.R., Ansari M.N.M., Shanks R.A., Universiti Tenaga Nasional, MY

An important issue for all composites is reduction of creep. The reinforcing fibers dramatically reduce creep, however nano-composites can improve tensile properties and toughness. The aim of this work is to prepare and characterize PLA [...]

Photo-destruction of cancer cells by NIR irradiation and graphene nano-sheets

Abdolahad M., Mohajerzadeh S., Janmaleki M., Akhavan O., University of Tehran, IR

In this paper, we present a novel cancer therapy method based on graphene inclusion in the cell solution and irradiation of the solution by near infrared lasers. The effect of various parameters such as graphene [...]

Biological effects of PLA-TCP nanocomposites on osteoblastic cells

Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Kim H.W., Kim J.W., Kim T.I., Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Seoul National University, KR

Composite substrates are considered as prospective matrix to populate and support cells in the bioengineering field. Synthetic degradable biomaterials, including poly(lactic acid) (PLA) and tricalcium phosphate (TCP), are widely used for matrix scaffold. In present [...]
