Plants open their pores and scientists strike gold

14.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Plants containing the element gold are already widely known. The flowering perennial plant alfafa, for example, has been cultivated by scientists to contain pure gold in its plant tissue. Now researchers from the Sun Yat-sen University in China have identified and investigated the characteristics of gold nanoparticles in two plant species growing in their natural environments. The study, led by Xiaoen Luo, is published in Springer's journal Environmental Chemistry Letters and has implications for the way gold nanoparticles are produced and absorbed from the environment.

Engineers at the University of California San Diego have developed tiny ultrasound-powered robots that can swim through blood, removing harmful bacteria along with the toxins they produce. These proof-of-concept nanorobots could one day offer a safe and efficient way to detoxify and decontaminate biological fluids.

Simultaneous monitoring of surfaces and protein distribution in cells

28.05. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

In a first proof-of-concept study, researchers at Ruhr-Universität Bochum (RUB) have combined two microscopy methods that render both a cell's surface and the distribution of a protein in the cell visible, at a resolution in the nanometre range. The method can be used for living cells. It might for example help analyse how cancer metastases are formed or assess the efficacy of specific drugs. The researchers from the nanoscopy workgroup at Rubion, the Central Unit for Ionbeams and Radionuclides at RUB, reported their findings in the renowned journal ACS Nano on May 23, 2018.

Breakthrough lab-on-a-chip technology that reveals how human cells communicate could lead to new treatments for cancer and autoimmune disorders.

Nanoparticles carrying two drugs can cross the blood-brain barrier and shrink glioblastoma tumors

24.05. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Glioblastoma multiforme, a type of brain tumor, is one of the most difficult-to-treat cancers. Only a handful of drugs are approved to treat glioblastoma, and the median life expectancy for patients diagnosed with the disease is less than 15 months.

New technique can track drug and gene delivery to cells

22.05. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

With targeted drug and gene therapies, finding the target cells is only half the battle. Once these agents reach a cell's surface, they still have to get inside and do their job.

Nanoparticles could offer a new way to help eradicate polio worldwide

21.05. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

A new nanoparticle vaccine developed by MIT researchers could assist efforts to eradicate polio worldwide. The vaccine, which delivers multiple doses in just one injection, could make it easier to immunize children in remote regions of Pakistan and other countries where the disease is still found.

Observing cellular activity, one molecule at a time

21.05. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Proteins and molecules assemble and disassemble naturally as part of many essential biological processes. It is very difficult to observe these mechanisms, which are often complex and take place at the nanometer scale, far smaller than the normal visible range. At EPFL, however, an interdisciplinary team of researchers has invented and applied a technique that allows these mechanisms to be examined with unprecedented precision. Their work is the subject of a paper published in Nature Nanotechnology.

Nanoparticles derived from tea leaves destroy lung cancer cells

21.05. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Nanoparticles derived from tea leaves inhibit the growth of lung cancer cells, destroying up to 80% of them, new research by a joint Swansea University and Indian team has shown.

Researchers operate lab-grown heart cells by remote control

18.05. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command—simply by shining a light on them and varying its intensity. The cells are grown on a material called graphene, which converts light into electricity, providing a more realistic environment than standard plastic or glass laboratory dishes.
