A team of researchers working at China's Fourth Hospital of Harbin Medical University has developed a new kind of male contraceptive that is easily reversed. In their paper published in the journal ACS Nano, the group describes their approach, the elements that went into making their contraceptive and how well it worked when tested on rats. [...]
A study released April 22 in The Lancet Respiratory Medicine shows that a booster dose of the Pfizer COVID-19 vaccine provides strong protection, roughly 80% to 90%, in the first few months against hospital admissions and emergency department visits caused by the delta and omicron variants. However, against omicron, this protection wanes over time—even after a [...]
In a paper published in the journal Biomacromolecules, a flexible and effective two-step method centered on triazine and azide-alkyne click-chemistry was devised for fluorescent labeling of nanoscale cellulose for use in microscopy applications. The Vast Potential of Cellulose Nanomaterials Cellulose, a major constituent of the cell wall in plants, is the most abundantly available structured [...]
Nucleic acids analysis is mainly used in pathogen detection, genetic disease identification and early cancer diagnosis. For example, quantitative analysis of circulating tumor DNA (ctDNA), a free DNA fragment derived from malignant cells which carries tumor specific sequence changes, can help obtain abundant information about tumors, including gene point mutation, genome integrity. Therefore, ctDNA [...]
In a study printed in the journal ACS Applied Materials & Interfaces, chemical vapor deposition approach was used to produce a nanometric hexagonal boron nitride (h-BN) coating on the cambered sides of every fiber in graphene glass fiber fabric (GGFF). Encapsulating Carbon-based Materials can Improve Oxidation Resistance Owing to their superior thermal and electrical characteristics, carbon-based materials like [...]
What makes boron-doped nanodiamonds so special? Boron-doped nanodiamonds for photocatalyis (BNDs) are a special type of diamond that has been modified with borons. They have been shown to enhance photocatalytic activation and thus increase their potential use in various fields. Nanodiamonds as Photocatalysts Diamond nanomaterials are promising candidates for inexpensive photocatalysts. They can be [...]
Scientists from the Suzhou Institute of Biomedical Engineering and Technology (SIBET) of the Chinese Academy of Sciences and the South China University of Technology collaborated to create near-infrared (NIR)-powered nano-assemblies with size and charge dual transformation for the integration of photo-controlled chemotherapy and immunotherapy in breast cancer. The findings of the study have been recently reported [...]
Something as simple as the motion of water drops on surfaces should actually be understood - one would think. In fact there are still numerous unanswered questions about the forces acting on a sliding droplet. A team of researchers from the Max Planck Institute for Polymer Research in collaboration with colleagues from TU Darmstadt [...]
People who suspect they may have COVID-19 could soon find out with a simple breath test that delivers results in three minutes. On Thursday, the U.S. Food and Drug Administration granted an emergency use authorization for a device called the InspectIR Covid-19 Breathalyzer. The test, which must be administered by a trained operator, demonstrates [...]
The development of a 3D nanoprinting platform that allows the printing of polymer materials with remarkable control and nanometer spatial accuracy is the subject of a new study published in the journal Nature Communications. Three-dimensional (3D) printing is a layer-by-layer processing technique that has found applications in a variety of fields, including tissue printing, aviation, [...]
