I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Rubbery properties help RNA nanoparticles target tumors efficiently and quickly leave body” Peixuan Guo, PhD, is a researcher with The Oho State University Comprehensive Cancer and The Ohio State University College of Pharmacy. Credit: The Ohio State University A new study by researchers at The Ohio State University Comprehensive Cancer Center—Arthur G. James Cancer Hospital…
“#Boron nitride nanofilms will replace antibiotics for protection against bacterial and fungal infections” Christina Gudz, co-author of the study, a researcher at the NUST MISIS Inorganic Nanomaterials Laboratory. Credit: Sergey Gnuskov/NUST MISIS NUST MISIS material scientists have presented antibacterial nano-coatings based on boron nitride, which are highly effective against microbial pathogens (up to 99.99%). They…
“#Novel virus-based colorimetric sensor can show true colors of airborne threats” Colorimetric sensors are easy-to-use devices that can reveal information, such as humidity, acidity, or the concentration of certain chemicals, through color changes and an intuitive interface Credit: Gwangju Institute of Science and Technology The ongoing COVID-19 pandemic has shown that the world needs technology…
“#A new method to produce gold nanoparticles in cancer cells” Credit: Pixabay/CC0 Public Domain Dipanjan Pan, professor of chemical, biochemical, and environmental engineering at UMBC, and collaborators published a seminal study in Nature Communications that demonstrates for the first time a method of biosynthesizing plasmonic gold nanoparticles within cancer cells, without the need for conventional…
“#Researchers develop anti-bacterial graphene face masks” Most carbon-containing materials can be converted into graphene using a commercial CO2 infrared laser system. Credit: City University of Hong Kong Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to “secondary transmission”. A research team…
“#Temporal-spatial order property of hollow multishelled structures enables sequential drug release” Schematic illustration of the sequential drug release by Hollow multishelled structure. Credit: Yang Nailiang Hollow multishelled structures (HoMSs), with relatively isolated cavities and hierarchal pores in the shells, are structurally similar to cells. They can be used as a carrier for antibacterial agents. A…
“#A new twist on DNA origami: Meta-DNA structures transform the DNA nanotechnology world” Models and transmission electron microscopy (TEM) images of various 3D polyhedra that were constructed by connecting the self-linked triangular M-DNA and rectangular M-DNA. From left to right: a tetrahedron, triangular bipyramid, octahedron, pentagonal bipyramid, triangular prism, rectangular prism, pentagonal and hexagonal prisms….
“#Scientists perfect knot-tying techniques with molecular string” Credit: University of Manchester A group of chemists from Manchester have successfully tied a series of microscopic knots using individual molecules for the first time, ushering in the advent of a form of nano-scale weaving which could create a new generation of advanced materials. The group based at…
“#Researchers create nanoclusters that mimic biomolecules” Credit: Journal of the American Chemical Society Biological systems come in all shapes, sizes and structures. Some of these structures, such as those found in DNA, RNA and proteins, are formed through complex molecular interactions that are not easily duplicated by inorganic materials. A research team led by Richard…
“#An on-skin durable nanomesh sensor to monitor natural skin motion” Fabrication and characterization of PU-PDMS core-sheath nanomesh conductors. (A to C) Schematic of the fabrication process. (D to F) Corresponding microscopic images of the (D) PU nanofiber sheet, (E) PU-PDMS core-sheath nanomesh, and (F) Au/PU-PDMS nanomesh conductor. (G) Strain-stress curves of the bare PU nanofiber…
