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 [...]

Bioactivation of Titanium Surfaces by Femtosecond laser Processing

Tavangar A., Tan B., Venkatakrishnan K., Ryerson University, CA

In this study, we propose a novel yet simple method to generate titanium oxide 3-D nanofibrous structures on the titanium implants using femtosecond laser machining. The femtosecond laser pulses hit the titanium substrate and generate [...]

siRNA and Paclitaxel Loaded PEG-PCL-PEI Tri-block Polymeric Micelle for Gene and Chemo-therapy Applications in Multidrug-resistance cancer cell

Hsu C.Y., National Chung Hsing University, TW

An annoying problem of chemotherapy was the drug resistance of cancer cell which was expression of multidrug-resistance associated proteins and resulted in ineffective treatment. To conquer this problem, a small interfering RNA (siRNA) molecule and [...]

Synergistic effects in mixed micellization between natural and synthetic block copolymers

Portnaya I., Khalfin R., Kesselman E., Danino D., Technion – Israel Institute of Technology, IL

Amphiphilic block copolymers and mixtures of amphiphiles find broad applications in numerous nano-technologies. In our previous study, we showed that interactions between a biological charged diblock copolymer, beta-casein, and a synthetic uncharged triblock copolymer, Lutrol [...]

Characterization of rMOMP-187 Peptide Encapsulated in PLGA 50:50 Nanoparticles

Taha M., Singh S.R., Butler C., Nyairo E., Dennis V.A., Alabama State University, US

The design of an immunization regimen capable of inducing sustained genital mucosal Th1 response is the current goal for a vaccine for humans to control the severe complications of genital infection by C. trachomatis. In [...]

Synthesis and characterization of new nanoparticles formed by milk whey proteins submitted to a thermal gelation process

Lopes J.R., Coimbra J.S.R., Teixeira A.V.N.C., De Oliveira E.B., Federal University of Viçosa, BR

In this work, nanostructures formed by the two whey proteins (alpha-lactoalbumin and beta-lactoglobulin) were synthesized througha thermal gelation process. The obtained proteic nanoparticles were characterized by using dynamic light scattering, transmission electron microscopy and atomic [...]
