Optical images of truncated tetrahedrons forming two large hexagonal grains at an anti-phase boundary (left), and transforming into a quasi-diamond phase that initiated at the anti-phase boundary (right). Scale bars are 25…

Proposed principle of X-ray mediated treatment of Alzheimer's disease (AD). a) Amyloid-β (Aβ) misfolds and forms soluble toxic oligomers and fibrils that accumulate…

Ionizable lipid structure influences mRNA delivery in human placental trophoblasts in vitro. Credit: Proceedings of the National Academy of Sciences (2024). DOI:…

Many vaccines, including vaccines for hepatitis B and whooping cough, consist of fragments of viral or bacterial proteins. These vaccines often include other molecules called adjuvants, which help to boost the…

In this Purdue-designed "tiny house" lab, Purdue researchers used instrumentation from GRIMM AEROSOL TECHNIK, a member of the DURAG GROUP, to more accurately study…

In the JS12 sample, a total of six Ti-bearing nanoparticles were identified (Figure 5a,e,l,p,t,v). Figure 5a presents the JS12-1 sample particle, where the high-resolution image (Figure 5b) reveals partially arranged crystal planes. The…

Osteoarthritis affects 530 million people worldwidePuwadol Jaturawutthichai/Shutterstock Drug-delivering nanoparticles might help treat osteoarthritis. In mice with signs of the condition, a single injection of the…

Researchers wanting to make use of locusts’ keen sense of smell to sniff out certain chemicals have found that injecting their brains with nanoparticles seems to make odour identification more reliable

At a Glance Researchers created nanoparticles that could deactivate immune cells and prevent severe allergic reactions in mice. The findings could lead to new approaches to prevent allergies and anaphylaxis in people. Anaphylaxis is…

Chronic obstructive pulmonary disease affects the lungsSEBASTIAN KAULITZKI/SCIENCE PHOTO LIBRARY Delivering medication to the lungs with inhalable nanoparticles may help treat chronic obstructive pulmonary disease…

Antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as “Gram-negative.” These bacteria have two cell membranes, making it more difficult for drugs to penetrate and…

3.1. Role of APTES in the Synthesis of SiO2@Si ShellsSEM images of TEOS- and APTES/TEOS-derived SiO2 shells precursors are shown in Figure 2.The FE-SEM image and FT-IR spectra of Si following piranha pre-treatment are illustrated in…

People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high…

Tiny particles inhaled during pregnancy could affect fetal growth and development, according to research in animal models funded by the NIEHS Outstanding New Environmental Scientist Program (ONES) program. At Rutgers, Stapleton is an…

Cell membranes generate powerful electric field gradients that are largely responsible for repelling nano-sized particles like proteins from the surface of the cell — a…

Tumors constantly shed DNA from dying cells, which briefly circulates in the patient’s bloodstream before it is quickly broken down. Many companies have created blood tests that can pick out this tumor DNA,…

Researchers at UC San Diego have developed modular nanoparticles that can be customized to target biological entities such as tumors, viruses or toxins. The surfaces of the nanoparticles are engineered to host biological molecules,…

2. The Applications of Nanoparticles in Influenza VaccinesInfluenza is an acute respiratory infection caused by the influenza virus, which often occurs in the form of seasonal epidemics. It is a highly infectious and rapidly spreading…

Many of the most promising new pharmaceuticals coming along in the drug development pathway are hydrophobic by nature — that is, they repel water, and are thus hard to dissolve in order to make them available to…

The characterization of the synthesized TeaNPs: SEM pictures of (A) B-TeaNPs, (B) G-TeaNPs, and (C) R-TeaNPs. Scale bars correspond to 500 nm. Size distributions of…

Designing Nanoparticles to Probe and Cross Biological Barriers to ImmunotherapyHHS Only Air date: Tuesday, November 21,…

RNA vaccines against Covid-19 have proven effective at reducing the severity of disease. However, a team of researchers at MIT is working on making them even better. By tweaking the design of the vaccines, the…

A nanoparticle coat helps an immunotherapy drug cross the blood-brain barrier in mice so it can target brain tumours more effectively…
