This new therapy depend on a two pronged approach. Titanium dioxide is a versatile photoreactive nanomaterial that can be bonded with biomolecules. Nanoparticles recognise and bind specifically to cancer cells when it is linked to an antibody. Focused visible light is shined onto the affected region, and the localized titanium dioxide reacts to the light by creating free oxygen radicals that interact with the mitochondria in the cancer cells. Mitochondria act as cellular energy plants, and when free radicals interfere with their biochemical pathways, mitochondria receive a signal to start cell death.

With this method it is possible to effectively attack the cancer which invade surrounding healthy cells using titanium dioxide unlike other cancer treatments like  radiotherapy and chemotherapy. But so far the tests have been done only on cells in a laboratory setting, animal testing is yet to be done and is planned for the next phase. Results show an almost 100 percent cancer cell toxicity rate after six hours of illumination, and 80 percent after 48 hours  and also other types of  cancers can be cured as well using different targeting molecules, but research is in the early stages.

Gene therapy with the aid of nanotechnology  can cure ovarian cancer, experiment conducted by US Researchers was able to deliver tiny synthetic particles carrying a payload of toxin worked as well as chemotherapy at killing ovarian cancer in mice without side effects. The  highlights of the study is the potential of nanotechnology in the design and manipulation of tiny synthetic particles, as a non viral way of getting DNA into cells, in the past there were interesting success with viruses but there are some safety concerns with Viruses. When they injected the treatment into the abdominal cavity of animals with ovarian cancer, it worked as well or better than the traditional chemotherapy drug combination of cisplatin and paclitaxel, which can cause DNA damage and a variety of side effects.

The Scientists tested different compounds until they found a biodegradable polymer that made a suitable delivery vehicle.To form the nanoparticle, the polymers are mixed with a gene that produces a modified form of the diphtheria toxin which is harmful only to ovarian cancer cells.

Use of nanotechnology for delivering drugs to cure ovarian cancer in humans is still have to be tested, researchers are planning to conduct test in humans within a year. if this test work it will be a promise for a new treatment for ovarian cancer, which kills thousands of woman all around the world.

The “trojan horse” therapy has the potential to directly target cancer cells with chemotherapy, rather than the current treatment that sees chemotherapy drugs injected into a cancer patient and attacking both cancer and healthy cells.

Brain implants are used to aid people suffering from Parkinson’s disease, depression and epilepsy, these implants with newly discovered micro electrodes are capable of communicating with individual neurons and to stimulate brain neurons with electrical impulses. The micro electrodes are also capable of  The current  devices usually wont last longer, its efficiency deteriorate after few months, but the new nanotechnology aided devices are expected to last at least two years

According to research team the new  coating is made of three compounds

1. A special electrically conductive nanoscale polymer called PEDOT
2. A gel like natural buffer alginate hydrogel
3. Nanofibers which is biodegradable, loaded with a controlled release anti inflammatory drug.

PEDOT polymer coating gives less electrical resitance to the micro electrodes which helps them to communicate more clearly with the neurons thus giving a big advantage over the current models.

Alginate hydrogel is capable of giving mechanical property to electrodes which is much similar to natural brain tissue and it is much superior than the current one.

Biodegradable nanofibers fight encapsulation  that occurs when the immune system tells the body to envelop foreign materials. Encapsulation is another reason these electrodes can stop functioning properly. The nanofibers fight this response well because they work with the alginate hydrogel to release the anti inflammatory drugs in a controlled, sustained way as the nanofibers themselves break down.

This dicovery is belived to assist  the  treatment for deafness, paralysis, blindness, epilepsy and Parkinson’s disease. Another feather in the cap of nanotechnology and health care.

Human body is having a network of blood streams that connects every part of our body ( capillaries and arteries ) this is a potential pathway for nanobots that can swim through human body to other for completing their assigned mission.

Wifi Guided nanobots

Wireless technology can be used for guiding nanobots through human body and to monitor their works. one thing scientists have to make sure before making such a system is to take care of the radiation aspects of wireless technology, it have to be safe for our human body.

Magnetic Fields for mobilizing nanobots

Magnetic fields can be used to to navigate nanobots from one part of body to another, the risk fator is less compared to wireless radiations.

Research team of University of Arkansas used magnetic nano tubes on nerves and nurons.Due to their structure and properties, magnetic nano tubes are among the most promising candidates of multifunctional nano materials for clinical diagnostic and therapeutic applications.

Research team worked on rats found that they were able to trigger cells called PC12 cells to differentiate into neurons by using nerve growth factor-incorporated magnetic nano tubes. They say that the findings suggest that magnetic nano tubes can be used to deliver nerve growth factor in order restore or repair damaged nerve cells.

Now It is computer / IT revolution an it had itz fair contribution in the field of Medical research but In coming decades we will see revolution in nanotechnology, quantum physics, human genome research and stem cell research, we will see things which we have never ever imagined before, and nanotechnology will be playing its big part in this never ever imagined health and Medical science revolution.

Regenerating  Tissues with the help of nanobots

Americans are spending a lot for anti aging medicines, in coming years nanotechnology will be assisting the new anti aging drive . What i can feel is  nanotechnology can create nanobots that can be injected into our body and these nanobots will be capable of repairing damaged and old tissues. Well it sounds bit weird ! dont worry we all will get used to it if after few decades !

Nanobots assigned with Mission

Nanometres can send deep inside our body to seek and destroy infected tissue parts and blocked arteries and seek and destroy and eliminate deadly HIV viruses from human body.

Nanotechnology for super human powers !

Imagine a human being who can run 100 miles without getting tired , a man/ woman  powerful enough to run as fast as 90 miles per second !These things are can be possible with nanotechnology,  nanobots  fused with quantum computers will be intelligent enough to alter  chemicals in our  body which can manipulate our functions to convert ourself into powerful human !

Some conservative people may object these nano ideas but later they will get used to it, during earlier days conservatives  objected discoveries made by scientists like Copernicans etc.

These days lot of scientific research are undergoing in universities around the world and every month we are reading about new nano discoveries
