Tamper-Resistant Pill Dispenser

The Johns Hopkins students’ tamper-resistant pill dispenser prototype features a fingerprint scanner, at left, which verifies the patient’s identity and then releases, at right, the correct dosage only within the prescribed time frame. You can whack it with a hammer, attack it with a drill, or even stab it with a screwdriver. Try as you might, you won’t be able to tamper with a high-tech pill dispenser. The U.S. Centers for Disease Control and Prevention have estimated that drug overdoses kill m...

Speedy Microscopic Submarines powered by Light

A team from Rice University has developed single-molecule nanosubmarines that could eventually be used to deliver medicines directly inside the body. Back in 2006, this same group developed nanocars, a single-molecule vehicle with four wheels, axles, and independent suspensions that could be “driven” across a terrestrial surface. Unfortunately, many of the nano-scale devices developed since then either required or emitted toxic chemicals. Several years ago, however, a new motor developed by a gr...

Eye drops with new chemical could clear up cataracts

Scientists have discovered a new chemical that could reverse cataracts, one of the leading causes of blindness. This new substance could be used in eye drops, greatly simplifying the treatment and making it accessible to the general population at a low price and without intrusive procedures. A cataract is a clouding of the lens in the eye leading to a decrease in vision. It can affect one or both eyes, generally evolves slowly, and causes about 50% of all the blindness cases in the world. Catara...

New Modification Method Could Bring Lifesaving Medications to Market

A safe and efficient technique using cellulose to get drugs to safely reach their target to save lives was created. Xiangtao Meng, a fourth-year graduate student in the College of Natural Resources and Environment has developed a new technique that can get drugs to market, and to patients, that would otherwise fail. Taking medications orally is typically much more practical for patients than methods like intravenous injections, but the bioavailability of a drug the amount that actually rea...

No More Needle Injections with Micro-Poration

Micro-poration is a painless method of transferring medication through the skin. The latest invention called micro-poration is a painless method of transferring medication (intraepidermal) into the body using laser technology. It is an alternative to injecting a needle. A handheld laser creates micro pores in the epidermis of the skin for the transfer of molecules. This device delivers medication and vaccinations directly through the skin. As an alternative to injecting a needle, mic...
