Herceptin and camptothecin are both powerful anticancer agents with key characteristics that limit their effectiveness in treating cancer. Patients treated with Herceptin, a monoclonal antibody that targets a growth promoting factor common to breast cancers, often relapse as their tumors become resistant to the drug. Overcoming camptotheci's toxicity and low solubility represent major therapeutic challenges. Now, researchers have used nanotechnology to combine the two into what so far appears to be a highly effective drug for treating aggressive breast cancer.

Laser frequency combs - high-precision tools for measuring different colors of light in an ever-growing range of applications - are not only getting smaller but also much easier to make. NIST physicists can now make the core of a miniature frequency comb in one minute. Conventional microfabrication techniques, by contrast, may require hours, days or even weeks.

Preparing semiconductor quantum dots is sometimes more of a black art than a science. That presents an obstacle to further progress in, for example, creating better solar cells or lighting devices, where quantum dots offer unique advantages that would be particularly useful if they could be used as basic building blocks for constructing larger nanoscale architectures.
