One of the biggest technological forces behind our rapidly changing world is our ability to manipulate objects on a smaller and smaller scale.The science that’s driving such progress is called nanotechnology.

Nanotechnology offers a way to direct interventions in the human body, potentially on a level of individual cells, using smart operating elements that are so small that they do not physically interfere with normal body function.

Here are some of the nanotechnology applications in health care.
MIT's new drug-delivering nanogel can be injected instead of requiring surgery.
Scientists are interested in using gels to deliver drugs, because they can be molded into specific shapes and designed to release their payload over a specified time period. However, current versions are not always practical, because they must be implanted surgically.

To help overcome that obstacle, MIT chemical engineers have designed a new type of self-healing hydrogel that could be injected through a syringe.Such gels can carry one or two drugs at a time. They are useful for treating cancer or heart disease.

This nanogel can change shape when applying stress to it, and it can re-heal when relaxing those forces. This property of this new nanogel allows the use of syringe or needle to inject them into the body without surgery.

MISOKA Toothbrush will clean your teeth without Toothpaste
The MISOKA toothbrush cleans your teeth by using the action of nano-sized mineral particles on the bristles to remove plaque from the surfaces of your teeth. It also gives the surfaces a smoother feel by making them more hydrophilic. This ground-breaking new toothbrush gives you the confidence of knowing you have brushed your teeth properly, leaving the inside of your mouth feeling fresher by making it more difficult for plaque and other material to stick to your teeth.

A group of Japanese techies have designed a toothbrush that uses super skinny nylon bristles wrapped in nano-size mineral ions to scrub teeth clean. Stains are lifted, plaque and other unwanted materials are avoided, and the enamel that defends your teeth from decay is protected.

It is used without toothpaste, just with water, and relies on mineral nanotechnology. It's named as Misoka toothbrush

Genetically engineered algae kills 90% of cancer cells without harming healthy cells
Algae has been genetically engineered to kill cancer cells without harming healthy cells. The algae nanoparticles, created by scientists in Australia, were found to kill 90% of cancer cells in cultured human cells. The algae was also successful at killing cancer in mice with tumours.

Researchers genetically engineered the algae to produce an antibody-binding protein on the surface of their shells. In turn, the antibody binds only to molecules found on cancer cells, meaning it could deliver drugs to the target cells.

As algae mostly only needs water and light to grow, the team believes the technique could reduce the cost and waste of nanoparticle manufacturing and has huge potential for future cancer treatments.

Laser printing with nanoparticles holds promise for medical research
Electronic devices that can not only be implanted in the human body but also completely dissolve on their own – known as “bioresorbable” electronics – are envisioned by many as one of medical technology’s next frontiers. A new study by Missouri University of Science and Technology researchers suggests that a laser printing technique using nanoparticles could help unlock a more cost-effective approach to building sturdier and safer components.

The new process allows for zinc nanoparticles to be sintered together through an evaporation and condensation process that avoids surface oxides. The fabricated, oxide-free zinc conductors demonstrated high electrical conductivity, mechanical durability and water dissolvability.

New sensors can detect single protein molecules
Modified carbon nanotubes could be used to track protein production by individual cells.

For the first time, MIT engineers have designed sensors that can detect single protein molecules as they are secreted by cells or even a single cell.

These sensors, which consist of chemically modified carbon nanotubes, could help scientists with any application that requires detecting very small amounts of protein, such as tracking viral infection, monitoring cells’ manufacturing of useful proteins, or revealing food contamination.

IBM NanoDLD for accelerating early detection of Diseases (e. g Cancer) with nanobiotechnology
3D Visualization of IBM Research NanoDLD Pillar Array Technology

3D rendering of IBM Research lab-on-a-chip nanotechnology that can separate biological particles down to 20 nanometers (nm) in diameter, a scale that gives access to important particles such as DNA, viruses and exosomes. The IBM team's work has focused on exosomes which are vesicles that contain information about the health status of the originating cell that they are shed from, revealing the presence and state of developing cancer and other diseases.

This innovation could potentially reveal signs of disease at the earliest of stages, before patients experience any physical symptoms and when the outcome from treatment is most positive.

Stretchable nano-devices towards smart contact lenses
Researchers at RMIT University and the University of Adelaide have joined forces to create a stretchable nano-scale device to manipulate light.The device manipulates light to such an extent that it can filter specific colours while still being transparent and could be used in the future to make smart contact lenses.

Using the technology, high-tech lenses could one day filter harmful optical radiation without interfering with vision – or in a more advanced version, transmit data and gather live vital information or even show information like a head-up display.
