Making Drinking Water Bacteria-Free

Efficient disinfection of water with silver sulfide quantum dots in a peptide coat

02-Mar-2023 - Water contaminated with bacteria is a large threat to global health. A Chinese research team has described a simple new method of disinfection in the journal Angewandte Chemie. It is based on tiny biocompatible assemblies of atoms, known as quantum dots, made of silver sulfide with caps made of a ...

Sweet coating for sour bones

Coating improves bone‐implant integration under osteoporosis: Physiological release of chemically-modified glycans from titanium implants suppresses inflammation for better bone healing

16-Feb-2021 - Osteoporosis is a leading global health challenge. Besides its own adverse effects, it also impairs the function of bone implants - normally made of a metal called titanium (Ti). Because there is less bone than normal in the implantation site, the implants could easily loosen, and persistent ...

New 3D chirality discovered and synthetically assembled

21-Feb-2020 - The origin of lives of human beings, animals and plants on earth is attributed to chirality because it is necessitated for the formation of biomolecules, such as nucleic acids, proteins, carbohydrates, etc. The studies on chirality have been becoming increasingly active and extensive due to its ...

4D imaging with liquid crystal microlenses

22-Nov-2019 - Most images captured by a camera lens are flat and two dimensional. Increasingly, 3D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4D imaging, which adds information on light polarization, could open up even more possibilities, but ...

Imprinted Spheres Fight Breast Cancer

Inhibition of HER2 on tumor cells by molecularly imprinted nanoparticles

05-Jul-2019 - A particularly aggressive, metastasizing form of cancer, HER2-positive breast cancer, may be treated with nanoscopic particles “imprinted” with specific binding sites for the receptor molecule HER2. As reported by Chinese researchers in the journal Angewandte Chemie, the selective binding of the ...

Sensor to search for artery hardening compounds in blood

22-Dec-2010 - A water-soluble zinc-based fluorescent sensor to detect pyrophosphate in blood has been developed by scientists from China. Pyrophosphate plays an important role in metabolic processes in the body but a lack of the compound can lead to Mönckeberg’s arteriosclerosis – calcium deposits in arteries. ...

Chemists create two-armed nanorobotic device to maneuver world's tiniest particles

18-Feb-2009 - Chemists at New York University and China's Nanjing University have developed a two-armed nanorobotic device that can manipulate molecules within a device built from DNA. The device is described in Nature Nanotechnology . "The aim of nanotechnology is to put specific atomic and molecular ...
