Unfortunately, cancer isn’t simply a single disease, and some types, like pancreas, brain or liver tumors, are still difficult to treat with chemotherapy, radiation therapy or surgery, leading to low survival rates for patients. Thankfully, new therapies are emerging, like therapeutic hyperthermia, which heats tumors by firing nanoparticles into tumor cells. In a new study […]Continue Reading ...
The dark skin pigment melanin protects us from the sun’s damaging rays by absorbing light energy and converting it to heat. This could make it a very effective tool in tumor diagnosis and treatment, as demonstrated by a team from the Technical University of Munich (TUM) and Helmholtz Zentrum München. The scientists managed to create […]Continue Reading ...
Feb 19 2019 Testa Analytical Solutions e.K reports on how its NanoBrook Omni particle size analyzer and BI-ZTU autotitrator can be used together to detect the onset of aggregation in nanoparticles. The NanoBrook Omni instrument offers a single powerful and accurate solution for particle sizing and zeta potential analysis. The instrument allows users to measure […]Continue Reading ...
Scientists from Russia and China discovered a host of new and unexpected nanoparticles and found a way to control their composition and properties the findings that break fresh ground in the use of nanoparticles. The results of their study were published in Physical Chemistry Chemical Physics journal. Micro objects, such as nanoparticles, can differ a […]Continue Reading ...
Dec 12 2018 Researchers have long-studied magnetotactic bacteria (MTB): aquatic microbes that have the ability to orientate themselves to magnetic fields. This unusual behavior makes them a subject of interest for improving our understanding of biomagnetism, and potentially harnessing their abilities for future technologies, such as medical nanorobots. Neutrons have been used to explore the […]Continue Reading ...
Zinc oxide (ZnO) has long been recognized as an effective sunscreen agent. However, there have been calls for sunscreens containing ZnO nanoparticles to be banned because of potential toxicity and the need for caution in the absence of safety data in humans. An important new study provides the first direct evidence that intact ZnO nanoparticles […]Continue Reading ...
A team of scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in collaboration with researchers from Monash University Australia, has succeeded in significantly increasing the stability and biocompatibility of special light-transducing nanoparticles. The team has developed the so-called “upconverting” nanoparticles that not only convert infrared light into UV-visible light, but also are water-soluble, remain stable in complex […]Continue Reading ...
New anti-thrombosis drug based on magnetite nanoparticles developed at ITMO University was successfully tested on animals. Preclinical studies conducted in terms of the project “PHARMA 2020” showed drug’s high efficacy and no side effects. Clot dissolution time of the new drug is 20 times shorter than the one of traditional medications. The range of permissible […]Continue Reading ...
Fat cells emit nanoparticles loaded with lipids that may keep fat tissue healthy and play a role in preventing diabetes, according to a new study published in Science.Continue Reading ...
Although magnetic nanoparticles are being used more and more in cell imaging and tissue bioengineering, what happens to them within stem cells in the long term remained undocumented. Researchers from CNRS, the Sorbonne Université, and universities Paris Diderot and Paris 13, have shown substantial degradation of these nanoparticles, followed in certain cases by the cells […]Continue Reading ...
Nanomedicine refers to field of science that uses nanotechnology for clinical operations. The use of nanoparticles (NPs) has specially been successful due to their structure. For example, NPs have the ability to cross biological barriers which boosts their effectiveness towards complicated drug delivery problems. This permeability allows NPs to reach biological targets such as brain […]Continue Reading ...
Chemical compounds formed in the process of arc welding and infiltrating the human body through the respiratory system are toxic because they contain metal oxidation products Working as part of an international group of toxicologists scientists of the Far Eastern Federal University (FEFU) have found that harmful nanoparticles are formed in the process of arc […]Continue Reading ...
It’s safe to slap on the sunscreen this summer – in repeated doses – despite what you have read about the potential toxicity of sunscreens. A new study led by the University of Queensland (UQ) and University of South Australia (UniSA) provides the first direct evidence that zinc oxide nanoparticles used in sunscreen neither penetrate […]Continue Reading ...
Because of their antimicrobial and antifungal properties, silver nanoparticles measuring between one and 100 nanometers (billionth of a meter) in size, are being incorporated outside the United States into a variety of kitchen products known as food contact materials (FCMs). Among the nanosilver-infused FCMs now on the market overseas are spatulas, baby mugs, storage containers, […]Continue Reading ...
A small clinical trial using gold nanoparticles that act as tumor-seeking missiles on a mission to remove prostate cancer has begun at The University of Texas Health Science Center at Houston (UTHealth). It is the first trial of its kind in the world. The nanoparticles, or nanoshells, are made of small layers of silica glass […]Continue Reading ...
