First insights into engineering crystal growth by atomically precise metal nanoclusters have been achieved in a study performed by researchers in Singapore, Saudi Arabia and Finland. The work was published in Nature Chemistry ("Supercrystal engineering of atomically precise gold nanoparticles promoted by surface dynamics"). Ordinary solid matter consists of atoms organized in a crystal lattice. The [...]

How can a drug be delivered exactly where it is needed, while limiting the risk of side effects? The use of nanoparticles to encapsulate a drug to protect it and the body until it reaches its point of action is being increasingly studied. However, this requires identifying the right nanoparticle for each drug according [...]

More profoundly than previously believed, the virus that causes COVID-19, SARS-CoV-2, can impact the brain for months after infection. The findings were presented at Neuroscience 2022, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. "Long COVID," which includes the neurological fallout [...]

Technology developed by researchers at the Indiana University School of Medicine that can change skin tissue into blood vessels and nerve cells has also shown promise as a treatment for traumatic muscle loss. Tissue nanotransfection is a minimally invasive nanochip device that can reprogram tissue function by applying a harmless electric spark to deliver [...]

Piran Kidambi, assistant professor of chemical and biomolecular engineering, recently had two papers appear in ACS Applied Materials and Interfaces and ACS Nano that respectively focus on a new approach to filter nanoparticles and explore ways to aid decarbonizing transportation. The paper published August 29, 2022, in ACS Applied Materials and Interfaces is about [...]

Terahertz radiation, whose wavelengths lie between those of microwaves and visible light, can penetrate many nonmetallic materials and detect signatures of certain molecules. These handy qualities could lend themselves to a wide array of applications, including airport security scanning, industrial quality control, astrophysical observations, nondestructive characterization of materials, and wireless communications with higher bandwidth [...]

Universitat Autònoma de Barcelona (UAB) researchers have developed a magnetic material capable of imitating the way the brain stores information. The material makes it possible to emulate the synapses of neurons and mimic, for the first time, the learning that occurs during deep sleep. Neuromorphic computing is a new computing paradigm in which the [...]

Nanoparticles, or tiny molecules that can deliver a payload of drug treatments and other agents, show great promise for treating cancers. Scientists can build them in various shapes with different materials, often as porous, crystal-like structures formed by a lattice of metal and organic compounds, or as capsules that enclose their contents inside a [...]

Just what is COVID capable of doing to the human brain? In a new study published in Molecular Psychiatry, researchers from Sweden and a Harvard-affiliated hospital in Boston tried to find out by creating “brain organoids,” or miniature brains about the size of a pinhead, and infected them with COVID. What they saw explained a lot: [...]

Researchers from the Université de Montréal in Canada have created and verified a new class of DNA-based drug transporters that are 20,000 times smaller than a human hair and could enhance cancer treatment and other diseases. Optimal Dosing at All Times: A Medical Challenge Providing and maintaining a therapeutic drug dosage during treatment is one of [...]
