Why not develop a tooth regenerating paste that can allow teeth to rebuild themselves by reversing decay? The peptide solution paste will contain a compound that will arrange itself into fibers when applied to a tooth. The fibers will form a scaffold to attract calcium and allow the tooth to rebuild itself from the inside.

The environmentally friendly bandage will use nanobubbles to attack the protective surface of fungi and bacteria. The nanobubbles, which function similar to oil droplets, will operate in conjunction with a particular blend of polysaccharides, damaging the microbes' cell walls and causing them to dehydrate and die. The polysaccharides are less toxic and less expensive than the antibiotics and silver used in current germ fighting bandages.

The idea is to create a portable, handheld device able to screen for brain hematoma quickly, saving valuable diagnosis time. While the brain's absorption of light should be symmetrical, areas of the brain with extra blood alter the amount of light absorbed and reflected. The scanner will use near UV light to detect blood collections in the brain, and will be used to test different areas of the brain. The scanner is meant to be used as a quick screen, aiding in the decision as...

The newly developed mChip can accurately diagnose HIV, costs only $1 to produce, and is the size of a credit card. The plastic mChip can accurately diagnose HIV with only a pinprick of blood. The chip takes advantage of microfluidics and eliminates the need for skilled technicians for analysis. The low cost combined with the size, speed, and accuracy could make the mChip extremely valuable for diagnosis in rural areas.

An artificial pancreas could eliminate the needs of diabetics for insulin injections by delivering the insulin automatically when required. People with type 1 diabetes can maintain normal sugar levels by engaging in low key activities after eating. Working off this idea, the pancreas would consist of a closed loop system containing a blood sugar monitor, insulin pump, activity monitors attached to the body, and a processing unit. Input from the activity and blood sugar monitors...

Injections of nanoparticles were proved to be effective while revealing blood clots location. The developed particles contain bismuth, which is actually a toxic heavy metal. The nanoparticles are rendered harmless by use of a compound that prevents the bismuth atoms from running loose in the body. Another molecule added to the nanoparticles' surface is attracted to fibrin, a particle found only in blood clots. The molecule draws the particles to the clots, where the bismuth shows...

The idea is to create a device that will provide a new level of night-time relief to asthma sufferers by provided cleaner air while they sleep. The device will work by directing a gentle column of cool, filtered air down onto the sleeping person. This cooler air will push away the particle-laden air that will rise out of the slightly warmer bed sheets.

A new method of stroke treatment is able to both restore circulation and remove clots with one insertion and has proven surprisingly effective. The device will be inserted into with a microcatheter. It will expand and trap the clot, and will be then retracted back to the catheter while the clot will be removed from the blood vessel by suction.

The idea is to create artificial red blood cells capable of transporting oxygen. The blood cells will be made using human stem cells. They will be natural and manufactured safely in large numbers. The artificial blood could eliminate the need to transport and store blood supplies, and could lower the chances of the transmission of blood borne diseases.

The idea is to develop a 'camera pill' which will deliver HD videos of the digestive tract in real time. The endoscopic camera will include an HD video camera, light source, radio transmitter, battery, and microprocessor to record and transmit images of the patient's digestive tract. It will also transmit its location within the person's body through the same ultra-wideband waves it will use to transmit the image data.
