Nanostructures made of DNA strands can encapsulate, release small-molecule drugs
Nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, McGill University researchers report in a new study.
Reproducing nature's chemistry: Researchers alter molecular properties in a new way
In their search for molecules with certain characteristics, chemists have produced millions of new, increasingly complex synthetic materials by altering molecules' chemical structures.
Researchers figure out why gold nanoparticles can penetrate cell walls
Cells are very good at protecting their precious contents—and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective ...
Eucalyptus macrocarpa is giving nano-medicine a boost
(Phys.org) —Murdoch University researchers have developed a 'green' method to create antibacterial gold nanoparticles for potential use in the medical field with the help of common eucalyptus leaves.
Using gold and light to study molecules in water
Thanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, ...
Insect-inspired super rubber moves toward practical uses in medicine
The remarkable, rubber-like protein that enables dragonflies, grasshoppers and other insects to flap their wings, jump and chirp has major potential uses in medicine, scientists conclude in an article in ...
Gold nanoparticles improve photodetector performance
The mineral molybdenum disulfide (MoS2), which, when solid, behaves in many ways like grease, has semiconducting properties that make it a promising alternative to silicon or graphene in electronic devices. It also strongly ...
Researchers use DNA origami technique to build nanoantennas with docking sites
Boosting immune therapy for cancer with nanoparticles
(Phys.org) —Activating the body's immune system to attack cancer and prevent it from recurring is one of the Holy Grails of cancer research because of its ability to specifically target cancer and to search almost anywhere ...
Nanoparticles help disrupt tumor blood supply, destroy tumors
(Phys.org) —In recent years, cancer researchers have been developing agents that destroy the blood vessels surrounding tumors with the goal of starving tumors to death. Some of these agents, such as tumor necrosis factor-alpha ...
Gold probes may offer valuable insight into cancer
(Phys.org) —Nanoprobes made from gold could be used to predict people's cancer risk – and the effectiveness of treatments, following research by University of Strathclyde academics.
Researchers use nanoparticles to speed up or slow down angiogenesis
Researchers invent cleaner way to produce concrete
Canadian Light Source (CLS) user Mark MacDonald is helping build better communities one concrete block at a time.
Sweet solutions for detecting disease
Based at the Institute of Chemistry in the Slovak Academy of Sciences, Ján Tkáč's research combines glycomics – the study of sugars in organisms – with biochip sensors based on nanoparticles and nanotubes. ...
