Tailoring Nanoparticles to Evade Immune Cells and Prevent Inflammatory Response

2017ACSNano-Leukosome.jpg

A Houston Methodist-led research team showed that the systemic administration of nanoparticles triggers an inflammatory response because of blood components accumulating on their surface.

How Nanoparticles Affect Flow Through Porous Stuff in Surprising Ways

POF-Dastvareh-fingers-fluid.jpg

Viscous fingering occurs in porous media where fluids of differing viscosity converge in finger-shaped patterns as a result of growing disturbances at the interface. Such instabilities are encountered in a wide variety of fields. Understanding different aspects of this phenomenon, and the variables that can control things like instabilities and velocity distribution dynamics, can potentially offer options to control and utilize these effects more effectively. Researchers report their findings in this week’s Physics of Fluids.

Photonic Crystal and Nanowire Combo Advances 'Photonic Integration'

APP-Notomi-nanowire-schematic.jpg

While bigger nanowires can improve light confinement and performance, it increases both energy consumption and device footprint -- both of which are considered “fatal” when it comes to integration. Addressing this problem, researchers came up with an approach that involves combining a sub-wavelength nanowire with a photonic crystal platform, which they report this week in the journal APL Photonics.

Making a ‘Beeline’ Past the Blood-Brain Barrier for Drug Delivery

NM253BBB.jpg

Most medicines can’t get through the blood-brain barrier (BBB), a highly selective membrane that separates the circulatory system from the fluid bathing the brain. Certain peptides in animal venoms, however, can navigate across it to inflict damage. Now, researchers are capitalizing on venomous sneak attacks by developing a strategy based on a bee-venom peptide, apamin, to deliver medications to the brain.

UAB Creates Triple-Threat Cancer-Fighting Polymer Capsules for Guided Drug Delivery

Guideddrugdeliverygraphic.png

Chemists have designed triple-threat cancer-fighting polymer capsules for guided drug delivery. They combine three traits: good imaging contrast with low-power ultrasound, stable packaging of the cancer drug doxorubicin, and ability to trigger drug release with low- or higher-power ultrasound.
