Meta-Lenses Bring Benchtop Performance to Small, Hand-Held Spectrometer

A research team of physicists from Harvard University has developed new hand-held spectrometers capable of the same performance as large, benchtop instruments. The researchers’ innovation, explained this week in APL Photonics, derives from their groundbreaking work in meta-lenses. The hand-held spectrometers offer real promise for applications ranging from health care diagnostics to environmental and food monitoring.

DNA “Barcoding” Allows Rapid Testing of Nanoparticles for Therapeutic Delivery

17C10201-P17-004.jpg

Using tiny snippets of DNA as “barcodes,” researchers have developed a new technique for rapidly screening the ability of nanoparticles to selectively deliver therapeutic genes to specific organs of the body. The technique could accelerate the development and use of gene therapies for such killers as heart disease, cancer and Parkinson’s disease.

Scientists Determine Precise 3-D Location and Identity of All 23,000 Atoms in a Nanoparticle

BerkeleyLabimage.jpg

Scientists used one of the world’s most powerful electron microscopes to map the precise location and chemical type of 23,000 atoms in an extremely small particle made of iron and platinum. Insights gained from the particle’s structure could lead to new ways to improve its magnetic performance for use in high-density, next-generation hard drives.

Understanding Breakups

POF-Chen-droplet-breakup.jpg

As interest and demand for nanotechnology continues to rise, so will the need for nanoscale printing and spraying, which relies on depositing tiny drops of liquid onto a surface. Now researchers from Tsinghua University in Beijing have developed a new theory that describes how such a nanosized droplet deforms and breaks up when it strikes a surface.
