From DNA to RNA to protein

Of the thousands of proteins produced in our cells, few are as important as the enzyme RNA polymerase (RNAP), which has the unique ability to faithfully copy genetic information from DNA.

Silica nanoparticles shown to boost reflection of ultrasonic energy

Targeted nanoparticles may eventually help physicians detect the very earliest stages of cancer using readily available ultrasound equipment, a new study from investigators at The Ohio State University suggests.

Advancing nanoparticle-based imaging and therapy of brain cancer

Brain cancer is one of the most difficult malignancies to detect and treat, in large part because of the difficulty in getting imaging and therapeutic agents past the so-called blood-brain barrier and into the brain.

Magnetic nanotechnology holds promise in fighting cancer

Detecting cancer and reinventing computing are two challenges that seemingly have little, if anything, to do with each other. That is, unless you are a nanotechnologist like Shan Wang, an associate professor of materials science and engineering and of electrical engineering at Stanford.

Colorimetric screening detects DNA, small molecules and proteins

Using the unusual color properties of gold at the nanoscale, scientists at Northwestern University have developed a "litmus test" for DNA and small molecule binding that eventually could be used by pharmaceutical companies to rapidly identify promising candidates for new anti-cancer drugs.
