Titania Nanotubes for Separation Applications

Panaitescu E., Ghosh M., Menon L., Northeastern University, US

We investigated the application of titania nanotubes arrays in the form of powders and membranes for water filtration and separation, and for employment in high-performance liquid chromatography. Such membranes have been successfully employed in photocatalytic [...]

Lipid Nanoparticles as Novel Carrier for Broad-spectrum Sunscreen Formulations

Deng X.Y., Zhou H.J., Chen Y.L., Wang J.M., Xia Q., Southeast University, CN

The most widely used UVA absorber in broad-spectrum sunscreens is 4-tert-butyl-4’-methoxydibenzoylmethane (avobenzone). In the sunlight, however, it will be photolysised rapidly and its photoprotection against UVA will greatly decrease. A photoprotective formulationwas developed with an [...]

Polymersomes and Imaging: A Quantitative Approach

Joseph A.S., Brown N.J., Battaglia G., University of Sheffield, UK

Nano-sized carriers are widely used as imaging tools. Quantification of the amount of carrier delivered provides useful informations in development and testing stages. This work describes a HPLC method to quantify fluorescent labelled polymersomes. Polymersomes [...]

Micrwave based microfluidic sensor

Tanbakuchi H., Bynum M., Brennen R., Whitener M., Agilent Technologies, US

SPR ( surface Plasmon Resonance) is an non destructive sensor capable of measuring the changes in refractive index above the gold surface (~300 nm) .The advantage of the SPR is in its capability of looking [...]
