Silver has long been used to thwart the spread of illness and in recent years silver nanoparticles have been incorporated into products ranging from sanitizers, odor-resistant clothes and washing machines to makeup, food packaging and sports equipment.

In plants and animals, the basic packaging units of DNA, which carry genetic information, are the so-called nucleosomes. A nucleosome consists of a segment of DNA wound around eight proteins known as histones.

Nature is filled with extraordinarily precise molecular shapes that fit together like a hand in glove. Proteins, for example, can assemble into a wide variety of well-defined shapes that grant them their function.

Researchers have delved into the composition of nanocomposites for ultraviolet metasurface fabrication and determined the ideal printing material for crafting them. Their findings are featured in the journal Microsystems & Nanoengineering on April 22.

Researchers from Japan have been working hard to keep their cool—or at least—keep their nanodevices from overheating. By adding a tiny coating of silicon dioxide to micro-sized silicon structures, they were able to show a significant increase in the rate of heat dissipated. This work may lead to smaller and cheaper electronic devices that can pack in more microcircuits.

A new technique in building DNA structures at a microscopic level has the potential to advance drug delivery and disease diagnosis, a study suggests.

A research team has developed a new thin film deposition process for tin selenide-based materials. This process utilizes the metal-organic chemical vapor deposition (MOCVD) method, enabling thin film deposition on large wafer surfaces at a low temperature of 200°C, achieving exceptional precision and scalability.

In recent years, the exceptional structure and fascinating electrical and optical properties of two-dimensional (2D) layered crystals have attracted widespread attention. Examples of such crystals include graphene, black phosphorus (BP), and transition metal dichalcogenides (TMDs).

An international research team led by Universität Hamburg, DESY, and Stanford University has developed a new approach to characterize the electric field of arbitrary plasmonic samples, like, for example, gold nanoparticles. Plasmonic materials are of particular interest due to their extraordinary efficiency at absorbing light, which is crucial for renewable energy and other technologies.

A research collaboration has devised a new way to quickly and reliably diversify the reactive end-groups on poly(2-oxazoline)s, a biocompatible polymer class.

DGIST Professor Jiwoong Yang's team in the Energy Science and Engineering Department has successfully manufactured high-performance, skin-attachable perovskite pure red light-emitting devices to create various forms of wearable displays.

Международному коллективу ученых удалось создать материал на основе кремния, покрытый наноразмерными острыми шипами. Такая нанотекстурированная поверхность способна убивать осевшие на нее вирусы парагриппа, механически прокалывая их оболочки. За 6 часов инкубации материал снижает количество жизнеспособных вирусов на 96%, что делает его перспективным для применения в больницах.

Nanoscale materials present us with astonishing chemical and physical properties that help materialize applications such as single molecular sensing and minimally invasive photothermal therapy—which were once just theories—into reality.

Nanostructured high entropy alloys—metals made from a chaotic mix of several different elements—show a lot of promise for use in industries such as aerospace and automotive because of their strength and stability at high temperatures compared with regular metals.

In a new paper published on May 1 in the journal Science Advances, researchers at Columbia Engineering used commercially available tabletop lasers to create tiny, atomically sharp nanostructures, or nanopatterns, in samples of a layered 2D material called hexagonal boron nitride (hBN).

Drug delivery researchers at Oregon State University have developed a device with the potential to improve gene therapy for patients with inherited lung diseases such as cystic fibrosis.

In the early 20th century, the development of a catalyst for ammonia synthesis by the Haber-Bosch method took more than 10,000 experiments before it was successful. The development of new materials is a time-consuming and costly process from design to commercialization.

While we usually think of disorder as a bad thing, a team of materials science researchers led by Rohan Mishra, from Washington University in St. Louis, and Jayakanth Ravichandran, from the University of Southern California, have revealed that—when it comes to certain crystals—a little structural disorder might have big impacts on useful optical properties.

The natural vein structure found within leaves—which has inspired the structural design of porous materials that can maximize mass transfer—could unlock improvements in energy storage, catalysis, and sensing thanks to a new twist on a century-old biophysical law.

A new study has been led by Prof. Xing-Hua Xia (State Key Lab of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University). While analyzing the infrared photoinduced force response of quartz, Dr. Jian Li observed a unique spectral response that is different from the far field infrared absorption spectrum.
