DHAKA, Bangladesh

A team of Bangladeshi researchers invented a low-cost technology to diagnose cancer through a blood test, local media reported on Wednesday.

The diagnose process will take only five minutes to deliver a result and it will cost about Taka 500 ($6), The Daily Star, a local daily, quoted the research team as saying during a press conference in Dhaka.

“Once the device is built, it will be able to detect cancer in just five minutes and it will cost around Taka 500 to diagnose cancer,” said Yasmeen Haque, a professor at the department of physics in Shahjalal University of Science and Technology (SUST).

The research team and the university administration have applied for the patent rights in the U.S. and Bangladesh for the technology “Method and System Based Nonlinear Optical Characteristic of Body Fluid for Diagnosis on Neoplasia”, according to the daily.

Haque, who led the research team, claimed that it will be the first time ever in the world when the cancer would be diagnosed using the nonlinear optics.

The technology will become operational within a next year, he added.

Education Minister of Bangladesh Nurul Islam Nahid termed the invention as “historic” for the country.

A group of Bangladeshi researchers on Wednesday said that they have invented a mechanism for detection of cancer through the blood test in less than five minutes at a cost of Tk 500, when currently cancers diagnosis is a long, costly and challenging process.

The group from the Shahjalal University of Science and Technology in Sylhet shared their finding at a press conference in Dhaka and said that they have applied the technology for a patent in the US and Bangladesh of invention titled ‘Method and system based on nonlinear optical characteristics of body fluids for diagnosis of neoplasia’.

Education minister Nurul Islam Nahid and University Grants Commission chairman Abdul Mannan said the much-needed simpler invention is a great achievement for the SUST and Bangladesh.

Nurul Islam Nahid said now a patient needs to spend Tk 8000 to Tk 10,000 for detection of cancer through tests those take six to seven days for providing results.

‘But with the new invention, cancer detection will require few minutes and less than Tk 500,’ he said.

‘Diagnosis of cancer using the nonlinear optics is for the first time ever in the world,’ lead researcher of group and SUST physics professor Yasmeen Haque said.

The technology enabled device will be ready within a year, she said.

Yasmeen Haque said that the phenomena of nonlinear optical phase change when a sufficiently high LASER beam is passed through the blood serum yields a characteristic nonlinearity parameter value.

This noninvasive method of obtaining blood sample leads to nonlinear optics-based methods for non-destructive quick diagnosis of cancer, she said.

The innovation is a part of the project titled ‘Innovative Biomarker Detection System Using Nonlinear Optics’ under Higher Education Quality Enhancement Project under the UGC with funds provided by the government and the World Bank.

A group of 25 researchers is working on the Tk 9-crore project since 2016.

The same principal based on which Object detection works...an AI program will compare how healthy sample looks like vs a sick sample...so when it looks at the target sample it will be able to tell if its healthy or not..the more data you feed it the more accurate the results.....any diagnosis that's done under a microscope can be done by this method.

Well I'd wait for further details but so far it looks legit. Shining a laser on body tissue emits specific signatures and that signature would be different for malignant tissue.

From cancer.gov.

"Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place.

When cancer develops, however, this orderly process breaks down. As cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed. These extra cells can divide without stopping and may form growths called tumors."

Laser therapy can detect optically through patterns which tissue samples are malignant and which are not.

Asia’s Rising Scientists: Hasibun Naher


In the chaos of earthquakes and tsunamis, there is order in the form of mathematics, says Associate Professor Hasibun Naher.

AsianScientist (Sep. 7, 2018) –

Physicist Eugene Wigner once wrote in a 1960 paper titled ‘The Unreasonable Effectiveness of Mathematics in the Natural World’ in which he noted how physical phenomena can be described and predicted with uncanny precision using mathematical formulas. This observation holds true even today, and Associate Professor Hasibun Naher of BRAC University, Bangladesh, is among the current generation of researchers seeking to unravel the secrets of nature through numbers.

A recipient of the 2018 OWSD-Elsevier Foundation Award, Naher has been applying numerical methods to the prediction of natural disasters such as earthquakes, storm surges and tsunamis. She hopes that by simulating and modeling these chaotic events, she will be able to save lives, perhaps through the development of early warning systems.

In this interview with Asian Scientist Magazine, Naher describes some of the challenges she faced as a scientist in a developing country and shares her aspirations for the future.

How would you summarize your research in a tweet?

Storm surges and tsunamis are among the world’s most dangerous natural hazards. Using mathematical equations and numerical methods to study these disasters, we could better predict them, and that will help save lives.


Describe a completed research project that you are most proud of.

I would not consider any research project as truly ‘completed,’ but I am proud of the work in which we use traveling wave solutions of nonlinear evolution equations to solve real world problems. It has always been my ambition to be a scientist, and I am happy that my research has allowed us to predict storm surges, perform tsunami simulations and carry out mathematical modeling of earthquakes. I’m also very proud to have received the 2018 OWSD-Elsevier Foundation Award for my research.

What do you hope to accomplish with your research in the next decade?

Our research team expects to predict wind speed, waves characteristics, maximum water levels, tsunami intensity and coastal inundation patterns.

Who (or what) motivated you to go into your field of study?

One of my early mentors was the father of my best friend. He was a very successful teacher, and together with my parents, encouraged me to do well academically. I love science because it is the engine of prosperity, and it forms the basis of new innovations and technologies.

What is the biggest adversity that you experienced in your research?

Numerous factors such as funding, research support, office facilities and time are necessary to achieve distinction in research. As a researcher in a developing country, some of these factors are hard to come by, but I think these challenges breed resourcefulness. However, beyond physical amenities and financial support, I would consider commitment, integrity and talent as other key ingredients for research excellence.

What are the biggest challenges facing the academic research community today, and how can we fix them?

The biggest challenges are a lack of training, motivation, inspiration and funding to carry out scientific research. In my opinion, scientists should have the opportunity to work with and learn from people all over the world, developing as a well-rounded person whilst making a contribution—large or small—to the knowledge of humankind.

If you had not become a scientist, what would you have done instead?

I would have been a medical doctor, which was what my father had wanted me to be.

Outside of work, what do you do to relax?

I read a lot. I also enjoy traveling and shopping.

If you had the power and resources to eradicate any world problem using your research, which one would you solve? I would prevent the loss of lives caused by tsunamis and earthquakes, and that can be achieved with better prediction tools.

What advice would you give to aspiring researchers in Asia?

Adopt a good reading habit and have an innovative mind. Creativity can be a most useful tool for a scientist. This article is from a monthly series called Asia’s Rising Scientists. Click here to read other articles in the series.
