MIT Scientist reach breakthrough in Neuro Science with the help of nanotechnology

Nano-Neuro Knitting: Spinal cord injuries, serious stroke and severe traumatic brain injuries affect more than 5 million Americans at a total cost of $65 billion a year in treatment.

Rodents blinded by a severed tract in their brains’ visual system had their sight partially restored within weeks, thanks to a tiny biodegradable scaffold invented by MIT bioengineers and neuroscientists.

This technique, which involves giving brain cells an internal matrix on which to regrow, just as ivy grows on a trellis, may one day help patients with traumatic brain injuries, spinal cord injuries and stroke.

The study, which will appear in the online early edition of the Proceedings of the National Academy of Sciences (PNAS) the week of March 13-17, is the first that uses nanotechnology to repair and heal the brain and restore function of a damaged brain region.

India Scientist invents Chip to Detect Cancer Early, Costs less than a dollar

BENGALURU:  Innovators often draw inspiration from personal experiences. Dr Deepika Sharma was spurred by a tragedy to come up with a device that brings down the costs of cancer detection.

Described as a ‘microfluidic low-cost organ-on-chip for cancer metastasis and drug optimisation’, the device can detect cancer early and help choose the right drugs.

Sharma’s mother died of urethral cancer five years ago. The death prodded the scientist to work on a device that could detect cancer early.

“If there had been a tool for early detection, we could have saved my mother,” she said.

The chip she is developing costs as little as Rs 30 and could cost even less if mass-produced. The project has been taken up by the Institute of Nano Science and Technology, Mohali, Punjab, to which she is attached.

Speaking to Express on the sidelines of the eighth Bangalore India Nano Summit, organised by the Department of IT, BT and Science and Technology, Jawaharlal Nehru Centre for Advanced Scientific Research and other organisations, Sharma said work on the device was progressing rapidly. It will hit the market within a year, she said.

She is working with Dr Bhanu Prakash and Asim Varma on the project. The prototypes, on display at the summit, have succeeded in detecting prostrate cancer, she disclosed.

Its transparent material, olydimethylsiloxane (PDMS), is etched using a laser to emulate endothelial cells, which line the insides of blood vessels.

When samples are placed on the sensor and observed under a microscope, medical professionals can tell if the patient has cancer, Shrma said.

cheap and effective

  • Mother’s death from cancer prodded scientist Dr Deepika Sharma to design cancer detecting device
  • Lowcost gadget can also be used to determine which treatment is appropriate for a patient
  • Currently used to detect prostrate cancer, it can be used to test on other cancers soon

Noting that the cost of such devices shoot up when patented, Sharma said her team was keen to keep the price affordable.

“We will publish results of its success in the detection of prostate cancer within a year. Soon, we will be able to test it on other cancers,” she said.

The device can also be used to determine which treatment is appropriate for a patient.

“People respond to medicines differently. With the PDMS sensor, we can ascertain which medicines suit them better, rather than let them consume a cocktail of drugs,” Asim Varma said.

The current technique for detecting cancer – biopsy, in which a tissue is taken and examined closely in a lab – is expensive, with prices varying across hospitals. The nano-device will be a cost-effective alternative, he said.

Scientists at IBM invent thermometer for nanoscale

The IBM lab responsible for inventing the scanning tunneling microscope and the atomic force microscope has invented another critical tool for helping us understand the nanoworld.


Accurately measuring the of objects at the nanoscale has been challenging scientists for decades. Current techniques are not accurate and they typically generate artifacts, limiting their reliability.

Motivated by this challenge and their need to precisely characterize the temperature of new transistor designs to meet the demand of future cognitive computers, scientists in Switzerland from IBM and ETH Zurich have invented a breakthrough technique to measure the temperature of nano- and macro-sized objects. The patent-pending invention is being disclosed for the first time today in the peer-review journal Nature Communications, “Temperature mapping of operating nanoscale devices by scanning probe thermometry.”

A History of Invention

In the 1980s, IBM scientists Gerd Binnig and the late Heinrich Rohrer wanted to directly explore a surface’s electronic structure and imperfections. The instrument they needed to take such measurements didn’t exist, yet. So they did what any good scientist would do: they invented one. It became known as the scanning tunneling microscope (STM), opening the door to nanotechnology. Just a few years later, the invention was recognized with the highest of honors, the Nobel Prize for Physics in 1986.
