DNA-Based Nanosensor Enables Nanoscale Measurement of pH Variation

Bioengineers at the University of Rome Tor Vergata and the University of Montreal have used DNA to develop a tool that detects and reacts to chemical changes caused by cancer cells and that may one day be used to deliver drugs to tumor cells.

Engineered Bacterium Includes Added Pair of DNA ‘Letters’

Scientists at The Scripps Research Institute (TSRI) have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature. The cells of this unique bacterium can replicate the unnatural DNA bases more or less normally, for as long as the molecular building blocks are supplied.

Silylated Nanocellulose Sponge Absorbs Oil, But Not Water

All industrial nations need large volumes of oil which is normally delivered by ocean-going tankers or via inland waterways to its destination. The most environmentally-friendly way of cleaning up nature after an oil spill accident is to absorb and recover the floating film of oil.

DNA Clamp Nanoswitches Offer a New Tool for Identifying Increased Risk of Cancer

An international research team has built molecular “clamps” out of DNA that offer a powerful new tool for identifying individuals with an increased risk of cancer. The clamp is capable of detecting genetic mutations, associated with cancer and other genetic diseases, with better specificity and affinity than more traditional techniques.

Nano Test Tube Created Out of HIV Virion

An interdisciplinary team of scientists from KU Leuven in Belgium has developed a new technique to examine how proteins interact with each other at the level of a single HIV viral particle. The technique allows scientists to study the life-threatening virus in detail and makes screening potential anti-HIV drugs quicker and more efficient. The technique can also be used to study other diseases.

Atom Movement Due to Absorption of Light Amplifies to Nanoscale Structural Changes in Protein Complex

The research groups of Janne Ihalainen (University of Jyväskylä) and Sebastian Westenhoff (University of Gothenburg) have clarified how the atom structure of bacterial red light photosensors changes when sensing light. The research reveals structural changes in phytochrome protein when illuminated.
