Transdermal patches—medicated adhesive pads placed on the skin that release drugs gradually for up to a week—have been available in the U.S. for more than 20 years. The first transdermal patch, approved by the U.S. Food and Drug Administration in 1979, delivered scopolamine to treat motion sickness. Since then, more than 35 transdermal patch products have been approved. Examples include the nicotine patch that helps people quit smoking, the lidocaine patch for relieving pain, and a patch containing hormone derivatives for preventing pregnancy.

Hard wiring the brain? Almost. Brain computer interface technologies that capture electrical brain waves as individuals imagine performing certain activities and translate the waves into computer commands will soon allow patients to operate word-processing programs, and perhaps even electric wheelchairs or robotic arms.

A liquid polymer gel that can be poured into torn cartilage tissue may offer a new approach to healing worn out joints. Tested on rabbits, the gel adapts to the shape of the tear and becomes the scaffolding for the body’s own cartilage cells to make new tissue.

DNA sequencing promises to improve the way in which diseases such as cancer are diagnosed, monitored, and treated. The technology relies on detecting fluorescent signals created when pieces of DNA bind together on a microchip. An emerging technology—electrophoresis on microchips—has aided DNA sequencing by miniaturizing processing technologies. Miniaturization has reduced the time needed to analyze samples and decreased the sample size required for testing.
