Synthesis and Characterization of Superparamagnetic Nanoparticles Coated with Carboxymethylated Cassava Starch for Drug Delivery System

Kasemwong K., Nanta P., Skolpap W., Ruktanonchai U.R., Nano Delivery System Laboratory, National Nanotechnology Center, TH

Magnetic nanoparticles (MNPs) are increasingly being considered for a number of biomedical applications due to their inherent ultra fine size, biocompatibility and superparamagnetic properties. The functional properties of the MNPs can be tailored for specific [...]

Layer-by-Layer Deposition of Cationic Polymers on Gold Nanoparticle for Non-viral Gene Delivery System

Saengkrit N., National Nanotechnology Center (NANOTEC), TH

In this study, gold nanoparticles displayed spherical shapes with an average size of 12 nm were synthesized. The nano-carriers for gene delivery were subsequently developed based on DNA adsorption on the gold/cationic polymer-scaffold. The multilayer [...]

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 [...]

Preparation and Characterization of Antibacterial TiO2/Poly[acrylamide-co-(acrylic acid)] Composite Hydrogel

Boonpavanitchakul K., Yiamsawas D., Kangwansupamonkon W., National Nanotechnology Center, National Science and Technology Development Agency, TH

A photocatalytically antibacterial TiO2/poly[acrylamide-co-(acrylic acid)] composite hydrogel from acrylamide (AAm) and acrylic acid (AAc) comonomers was prepared by free-radical aqueous polymerization using N,N’-methylenebisacrylamide (N-MBA) as a crosslinker, ammonium persulfate (APS) as an initiator, and Degussa [...]

Preparation of Ag/TiO2/bamboo charcoal composite based on chemical and electrochemical synthesis: characterization and antibacterial study

Pookboonmee S., Laohhasurayotin K., National Science and Technology Development Agency, TH

A combined function of photocatalysis, antibacterial, and adsorption was introduced as a composite powder in the form of Ag/TiO2/BC. The powder was characterized by SEM, TEM, and XRD for confirmation of the obtained product. The [...]

Mechanical Properties of PLA-Jute Composites by Using Natural Rubber and Epoxidized Natural Rubber as Impact Modifiers : Effect of Molding Technique

Ruksakulpiwat Y., Tonimit P., Kluengsamrong J., Suranaree University of Technology, TH

Jute fiber was used as a reinforcing fiber in poly (lactic acid) (PLA) composites. Natural rubber (NR) and epoxidized natural rubber (ENR) are used as impact modifiers of jute-PLA composite. The composite specimens were prepared [...]

The study of using glycidyl methacrylate grafted natural rubber as an impact modifier of polylactic acid

Juntuek P., Ruksakulpiwat C., Ruksakulpiwat Y., humsamrong P., Ruksakulpiwat C., Ruksakulpiwat Y., Suranaree University of Technology, TH

Glycidyl methacrylate (GMA) was grafted onto natural rubber (NR) using emulsion polymerization method and using cumene hydroperoxide (CHP) and tetraethylenepentamine (TEPA) as an initiator. Glycidyl methacrylate grafted natural rubber (NR-g-GMA) were melt blended with polylactic [...]
