Characterization on nanoparticle drug delivery carriers

Murphy C., Jankevics-Jones H., Malvern Instruments Ltd, UK

Nanoparticle controlled drug delivery technology represents a rapidly advancing arena in medical treatment. These delivery systems offer numerous advances compared to conventional dosage forms which include improved efficacy, reduced toxicity and improved patient compliance and [...]

Characterisation of Native-State Soft Matter using ‘Multi-Mode’ Electron Microscopy

Stokes D.J., Baken E., Lich B.H., Hubert D.H.W., FEI Company, NL

Soft condensed matter and complex fluids are of increasing technological significance. It is therefore crucial that we extend the capabilities of conventional solid state imaging and analytical techniques to include the observation of materials such [...]

Field-induced Dielectrophoresis and Phase Separation for Manipulating Particles in Microfluidics

Bennett D.J., Khusid B., James C.D., Galambos P.C., Okandan M., Jacqmin D., Kumar A., Qiu Z., Acrivos A., New Jersey Institute of Technology, US

We report observations of new many-body phenomena in the micro-scale behavior of a suspension subject to a high-gradient strong alternating current (ac) field and shear. Their origin is dielectrophoresis accompanied by the field-induced phase separation [...]
