Paper test strip could help heart failure patients monitor their condition at home

ScienceDaily.com: Nanotechnology News - 24 мая, 2017 - 18:00
Contrary to the condition's name, heart failure doesn't mean the heart has stopped pumping -- it's just not working at full strength. It can often be managed with medications and lifestyle changes, but its progression needs to be monitored closely. Now scientists have developed a new test strip that could potentially allow patients to do this at home for the first time.

A fresh look inside the protein nano-machines

ScienceDaily.com: Nanotechnology News - 24 мая, 2017 - 15:44
Proteins perform vital functions, they digest food and fight infections. They are in fact nano-machines, each one of them designed to perform a specific task. But how did they evolve to match those needs, how did the genes encode the structure and function of proteins? Researchers have conducted a study that tackles this yet unanswered question.

Electrochemical energy storage with porous one-dimensional (1D) nanomaterials

Nanowerk.com - 24 мая, 2017 - 14:34
The development of porous one-dimensional (1D) nanomaterials with designed properties and architectures has led to significant advances in electrochemical energy storage. A recent review article highlights the state-of-the-art on porous 1D nanostructures, from methodologies for rational and controllable synthesis (electrospinning, liquid phase method, template-assisted method, chemical deposition method, and chemical etching) to their successful application in different types of energy storage devices.

Explainer: what is nanomedicine and how can it improve childhood cancer treatment?

Nanowerk.com - 24 мая, 2017 - 13:58
Nanomedicine has great potential to safely treat children's cancer. However, it is currently stymied by too little research. About two-thirds of research attention in nanomedicine therapeutics, of more 250 nanomedicine products, is focused on cancer. Yet this isn't translating into new cancer treatments for children coming to market.
