To improve the performance of nanostructured calcium carbonate in gene delivery, a hydrophilic polysaccharide, alginate, was added to calcium carbonate co-precipitation systems to form alginate/CaCO(3)/DNA nanoparticles. The size and ζ-potential of the nanoparticles were measured by a zetasizer. Due to the existence of alginate chains which retarded the growth of calcium carbonate based co-prec...

Natural biopolymers are widely used in the field of drug and gene delivery. In this study, alginate nanoparticles were prepared using water-in-oil reverse microemulsion as a template followed by calcium crosslinking of guluronic acid units of alginate polymer. After collected by ultracentrifugation, alginate nanoparticles were analyzed by electron microscopy to obtain the size and morphology wh...

Composite particles with multifunctions have been extensively utilized for various applications. Bubble particles can be applied for ultrasound-mediated imaging, drug delivery, absorbers, cell culture, etc. This study proposes a one-step strategy to obtain Pt nanoparticles loaded in alginate bubbles. A needle-based droplet formation was used to generate uniform alginate particles about 2 mm in ...

Reverse microemulsion was used as a template to fabricate chitosan-alginate core-shell nanoparticles encapsulated with enhanced green fluorescent protein (EGFP)-encoded plasmids. The average size of DNA-entrapped nanoparticles measured by dynamic light scattering was increased proportionally, with the N/P ratios ranging from 5 to 20. These alginate-coated chitosan nanoparticles endocytosed by N...

Silver nanoparticles (Ag-NPs) have been successfully synthesized using ultrasound irradiation in the sodium alginate media. AgNO3 and ultrasound irradiation have been used as silver precursor and physical reducing agent to accelerate the synthesis of Ag-NPs. The presence of Ag-NPs can be detected from the changing color of the suspensions. The silver ion reduction was confirmed through the surf...
