Lighting the Way for Nanotube Innovation

Scientists have learned how to place crystalline defects in new materials with atomic-scale precision. This enables materials that can control excitons—energy carriers similar to subatomic particles. New research reveals how to create local energy wells that “capture” the excitons. This small but important step could lead to smaller, more efficient components for optical telecommunications.

Study Sheds Light on Mechanism of Liposome Accumulation in Tumors

Dmitri Simberg, PhD, associate professor in the University of Colorado Skaggs School of Pharmacy, released a new study of the effectiveness of different types of fluorescent labels used to monitor the accumulation of liposomes in tumors. The study was published on July 1, 2021, in ACS Nano.

Breaching the Blood-Brain Barrier to Deliver Precious Payloads

RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven’t been very useful in treating brain tumors and other brain disease. But a team of researchers at Georgia Tech and Emory University has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery of potent medicine to brain tumors.

April Snapshots

Science Snapshots from Berkeley Lab: X-rays accelerate battery R&D; infrared microscopy goes off grid; substrates support 2D tech

Study: Turning a coronavirus protein into a nanoparticle could be key to an effective COVID-19 vaccine

One of the proteins on the virus – located on the characteristic COVID spike – has a component called the receptor-binding domain, or RBD, which is its “Achilles heel.” That is, he said, antibodies against this part of the virus have the potential to the neutralize the virus.

Scientists Capture Candid Snapshots of Electrons Harvesting Light at the Atomic Scale

A team of scientists led by Berkeley Lab has gained important new insight into electrons’ role in the harvesting of light in artificial photosynthesis systems.

Lighting the Way from Repulsion to Attraction

Scientists are working on ways to build atomic structures to specifications and are studying these methods on a larger scale using ‘big atoms.’ These ‘big atoms’ are micro-particles of silica mixed into liquid crystals. Silica particles, when mixed into liquid crystals, can act a lot like individual atoms. The geometry of the particles determines how they interact with each other the same way the electrons around an atom determine how it interacts with other atoms. Scientists can observe interactions in these ‘big atoms’ with optical microscopes, removing the need for atomic-scale imaging.

Science Snapshot From Berkeley Lab – a biocompatible material that turns up the heat on antibacterial-resistant diseases

Scientists at Berkeley Lab’s Molecular Foundry have designed a biocompatible polymer that has the potential to advance photothermal therapy, a technique that deploys near-infrared light to combat antibacterial-resistant infections and cancer.
