New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick ...

Cockle shells picked to treat dog cancer

The calcium mineral from which many shellfish, such as cockles, make their shells can be used to form nanoparticles. These nanoparticles can then be "loaded" with small drug molecules, such as anticancer drugs.

Membrane nanopore transport gets picky

Trying to determine how negatively charged ions squeeze through a carbon nanotube 20,000 times smaller than a human hair is no easy feat.

Breaking down stubborn cellulose in timelapse

Researchers at TU Graz in Austria have for the first time ever succeeded in visualizing at the single-molecule level the processes involved in a biological nanomachine, known as the cellulosome, as it degrades crystalline ...

New integrated device for nanometer-scale sensing

Researchers at Eindhoven University of Technology have developed a new, integrated optical sensor that provides increased resolution in measurements and paves the way for fully integrated and compact optical sensors including ...

Nanobowls serve up chemotherapy drugs to cancer cells

For decades, scientists have explored the use of liposomes—hollow spheres made of lipid bilayers—to deliver chemotherapy drugs to tumor cells. But drugs can sometimes leak out of liposomes before they reach their destination, ...

New wearable sensor tracks vitamin C levels in sweat

A team at the University of California San Diego has developed a wearable, non invasive vitamin C sensor that could provide a new, highly personalized option for users to track their daily nutritional intake and dietary adherence. ...

Nanomaterial significantly enhances potential COVID-19 therapy

Niclosamide, a drug used to treat tapeworms, has been found to have strong antiviral effect against SARS-CoV-2, the virus causing the COVID-19 pandemic. But the drug itself has limited potential because its structure makes ...

Silver nanocubes make point-of-care diagnostics easier to read

Engineers at Duke University have shown that nanosized silver cubes can make diagnostic tests that rely on fluorescence easier to read by making them more than 150 times brighter. Combined with an emerging point-of-care diagnostic ...

New anti-COVID-19 nanocoating surface developed

Ben-Gurion University of the Negev (BGU) researchers are developing safe anti-viral nanoparticle coatings that demonstrate significant potential in preventing active surface infection with SARS-CoV-2.

A new imaging approach to see multiple proteins simultaneously

Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) have developed an innovative method to visualize up to tens of different proteins simultaneously in the same cell. This technology could help scientists ...

Raise your glass: New nanotech clears haze from white wine

Sauvignon blanc, semillon, or chardonnay—when you reach for your favorite white, it's the clean, clear sparkle that first catches your eye. Or does it? When white wines look cloudy it's a sign of protein instability, and ...

Material manufacturing from particles takes a giant step forward

Tiny fibrils extracted from plants have been getting a lot of attention for their strength. These nanomaterials have shown great promise in outperforming plastics, and even replacing them. A team led by Aalto University has ...

Chemistry breakthrough could speed up drug development

Scientists have successfully developed a new technique to reliably grow crystals of organic soluble molecules from nanoscale droplets, unlocking the potential of accelerated new drug development.

Second skin protects against chemical, biological agents

Recent events such as the COVID-19 pandemic and the use of chemical weapons in the Syria conflict have provided a stark reminder of the plethora of chemical and biological threats that soldiers, medical personnel and first ...
