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 [...]

Cationic Nanoparticles Effectively Delivered VEGF SiRNA in A549 Cells

Yang T., Li X., Liu Y., Liu Y., Bai S., Husson University, US

Recent discovery of small interfering RNA (SiRNA) that silences growth factors appears to improve effectiveness and safety of cancer therapy. Unfortunately, delivery of SiRNA to cancer cells is a major obstacle. Our work is focused [...]

Biodegradable micro and nanoparticles for controlled drug release

Mattu C., Sartori S., Ranzato E., Boffito M., Li R., Ciardelli G., Politecnico di Torino, IT

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 [...]

Nanoparticles co-encapsulating hVEGF and hAng-1 can induce mitotic and antiapoptotic effect on vascular endothelial cells

Khan A.A., Paul A., Abbasi S., Prakash S., McGill University, CA

This study demonstrates the combined effect of the angiogenic proteins, hVEGF and hAng-1, coencapsulated in human serum albumin (HSA) nanoparticles (NPs), towards human umbilical vein endothelial cells (HUVECs) and an evaluation of the potential application [...]

Numerical Simulation of the Solidification of Water-Based Nanofluid

El Hasadi Y.M.F., Khodadadi J.M., Auburn University, US

Nanofluids are colloidal suspensions which they consist particles in the size range of 100-1 nm. In the recent years nanofluids kept the attention of the scientific community due to their improved thermal physical properties compared [...]

Using nanofluids to enhance the operation of solar energy systems

Otanicar T., Loyola Marymount University, US

Nanofluids have garnered a lot of attention for their potential to modify thermal properties, particularly the thermal conductivity. While these modifications have been heavily investigated within the heat transfer and materials community, nanofluids additionally offer [...]

A new route to control the enhancement of structural and anisotropy ordering in two-dimensional particle arrays

Regtmeier A., Wittbracht F., Dück I., Rempel T., Weddemann A., Hütten A., Bielefeld University, DE

For the realization of data storage devices two fundamental requirements are necessary to guarantee good functionality: a) particles need to be arranged within a sizeable, two-dimensional monolayer of high spatial ordering and b) magnetic states [...]
