Viral respiratory diseases are easily transmissible and can spread rapidly across the globe, causing significant damage. The ongoing COVID-19 pandemic is a testament to this. In the past too, other viruses have caused massive respiratory disease outbreaks: for example, a subtype of the influenza virus, the type A H1N1 virus, was responsible for the Spanish […]

Researchers at Columbia Engineering report today that they have developed the first nanomaterial that demonstrates “photon avalanching,” a process that is unrivaled in its combination of extreme nonlinear optical behavior and efficiency. The realization of photon avalanching in nanoparticle form opens up a host of sought-after applications, from real-time super-resolution optical microscopy, precise temperature and […]

For about one in 13 children in the U.S., normally harmless foodstuffs such as milk, eggs and peanuts can send the body’s natural defences into overdrive. https://nano-magazine.com/news/2021/1/18/nanoparticle-shows-promising-results-for-treating-severe-allergies?ss_source=sscampaigns&ss_campaign_id=6008005d36c4f5032d86914e&ss_email_id=60087017bafa08315140f4bf&ss_campaign_name=Researchers+identify+nanoparticles+that+could+deliver+therapeutic+mRNA&ss_campaign_sent_date=2021-01-20T18%3A06%3A36Z

Researchers at Children’s Hospital of Philadelphia and the School of Engineering and Applied Science at the University of Pennsylvania have identified ionizable lipid nanoparticles that could be used to deliver mRNA as part of fetal therapy. The proof-of-concept study, published today in Science Advances, engineered and screened a number of lipid nanoparticle formulations for targeting […]

Lasers are used in a range of everyday devices, harnessing the power of light molecules, photons, – lined up to form highly concentrated beams of light – to perform now common tasks such as scanning barcodes and removing tattoos. https://www.azonano.com/news.aspx?newsID=37653&utm_source=azonetwork_newsletter&utm_medium=email&utm_campaign=lasers_newsletter_20_january_2021

The COVID-19 pandemic is raising fears of new pathogens such as viruses or drug-resistant bacteria. On this note, a Korean research team has recently drawn attention for developing the technology for removing antibiotic-resistant bacteria by controlling the surface texture of nanomaterials. https://nano-magazine.com/news/2021/1/11/nanocrystals-that-eradicate-bacterial-biofilms?ss_source=sscampaigns&ss_campaign_id=5ffed760015f2a00220fcdf9&ss_email_id=5fff3c6d53f2aa3540bf0412&ss_campaign_name=Nanocrystals+that+eradicate+bacterial+biofilms&ss_campaign_sent_date=2021-01-13T18%3A33%3A20Z

Lithium-ion batteries power our modern way of life. Using ionic battery technology, they store electrical energy, allowing our devices to come with us wherever we go. They can also store electricity from renewable sources, making them a viable alternative to fossil fuels. https://www.azom.com/article.aspx?ArticleID=19108&utm_source=azonetwork_newsletter&utm_medium=email&utm_campaign=atomic_force_microscopy_afm_newsletter_14_january_2021

When the atomic force microscope (AFM) was invented in 1986, a commercial need was born (Binnig, Quate and Gerber, 1986). Atomic force microscopy (AFM) utilizes an extremely sharp-tipped probe – mere nanometers thick at the end – attached to a precisely sensitive cantilever and sensor. The manufacture of these cantilevers has been made possible due […]

Photoelectrochemical devices capture light energy and generate alternative energy storage compounds. These devices rely on semiconductors to capture light energy, and nanocatalysts to drive chemical reactions. However, the way in which the two components work together is not well understood. https://www.azom.com/article.aspx?ArticleID=18650&utm_source=azonetwork_newsletter&utm_medium=email&utm_campaign=atomic_force_microscopy_afm_newsletter_14_january_2021

An international team of scientists led by Kartik Ayyer from the MPSD has obtained some of the sharpest possible 3-D images of gold nanoparticles.
