The “ lab on a chip” system costs less than a penny to make and can test cells for possible signs of diseases such as tuberculosis, HIV, malaria and even cancer. The printable chip needs an ordinary inkjet printer and conductive nanoparticle ink.

“One of our main goals is to provide this low cost platform in low- resource settings area in Asia, Africa and even Latin American nations. We are very hopeful that this inexpensive and multi-functional platform enables greater individual access to diagnostic facilities in the developing countries,” says Rahim Esfandyarpour of Stanford University in an email to localhost/muslim.

Timely detection of the disease plays an important role in the treatment to save lives. According to the World Health Organization (WHO), breast cancer mortality is increasing in developing nations as compared to developed countries. 58 per cent of deaths occur in developing nation due to low detection of this cancer at early stage.

The survival rates of breast cancer are as high as 80 per cent in developed nations but almost half (40 per cent) in the low-income nations just because the absence of timely and affordable diagnosis facilities.

Draw, download, print and predict

The simple hand held lab comprises of two important parts; a clear silicone microfluidic chamber sits on a reusable electronic strip.

The silicone chamber holds the sample cells of disease and the electronic chip is made from polyester sheet on which circuit is carved through commercially available nano particle ink acts as conductor. The whole printing process needs just 20 minutes. User can download electronic designs to print for the different applications and this feature turns the strip into a multifunctional diagnostic platform

Instead of using fluorescent ink or other markers to look for diseases, the chip works by applying electric charge which separates the cells and drive them into different directions. Due to their “polarizability” – intrinsic electrical features – the cells pulled in different directions in the microfluidic chamber. This process helps to catch the disease at early stage, for instance it can separate the tumor cells in the blood sample as their charges are different.

Apart from separating the cells by type, the researchers can also switch to counting cells by printing a new circuit at the strip. In future an open database of different designs could be set for the required tasks that can easily be downloaded, printed out and use for various applications.

From lab to the field

The technology is simple with the high-tech concepts of microfluidics, electronics and inkjet printing technology. The low cost compact lab on chip could revolutionize disease diagnostics especially in the remote areas of low income regions. In future, only one lab assistant can produce cheap strip to look for HIV or malaria in a village in Africa or at the mountains of Afghanistan. The team is now looking for investors to commercialize their promising idea.

“We think the technology has the potential to not only advance health care, but also to accelerate basic and applied research around the globe. Although we have very promising results, we expect a bit more work toward commercialization of the solution,” Esfandyarpour added.

Rahim Esfandyarpour received his BSc from K N Toosi University in Tehran, Iran.

After doctorate in Electrical Engineering from Stanford University, he is currently working at the Genome Technology Center at the same university.

Biomedical research in the Arab region https://muslim-science.com/biomedical-research-in-the-arab-region/ https://muslim-science.com/biomedical-research-in-the-arab-region/#respond Sat, 29 Nov 2014 19:12:51 +0000 http://muslim-science.com/?p=2789 Biomedical research in the Arab region

Published online 20 November 2014

In the not-too-distant past, biomedical research was conducted almost exclusively in North America and Western Europe. While Asia and South America have made impressive strides in contributing to scientific output over the past two decades, the Arab world is still lagging.

Ali A. Bazarbachi, Samia J. Khoury and Mohamed H. Sayegh

Populations in the Middle East are generally afflicted with diseases similar to those prevalent in Western countries. These include cardiovascular diseases, cancer, and neurological disorders. However, regional specificities have had an impact.

A high rate of consanguinity has led to various hereditary disorders. There has also been a significant increase in metabolic disorders, specifically in the Gulf region, largely attributed to widespread changes in diet and lifestyle. Furthermore, healthcare systems have been undermined by political instability and strife, resulting in an increase in infectious diseases, malnutrition and disability.

The concept of advanced biomedical research still does not exist in most of the region, with the exception of Turkey and Iran. Recent developments in biomedical research have surfaced in Saudi Arabia and the Gulf region as well, with major investment in the creation of research infrastructure and research funding. But the fruits of such effort are yet to appear because of the absence of a critical mass of committed scientists.

Most of the region’s medical schools and universities offer the transmission of ‘second-hand’ knowledge in the absence of a true research culture. A general disinterest in scientific research adversely affects the quality of teaching and cultivates a culture of apathy.

Most active research is championed by a few dynamic individuals, based on their earlier achievements abroad, with little or no institutional incentives. They mostly collaborate with their university of origin in the United States or Europe and there is scant meaningful collaboration between institutions at the national or regional level.

The region’s participation in the advancement of science and medical discovery is important. Breakthroughs will improve quality of life for Middle Eastern people and ensure better patient care. There is also a need to attract internationally renowned investigators to create a nucleus of future scientific leaders.

Scientists should be encouraged toward personal academic growth. We need to involve students in medical research by bringing the latest research findings, including the results of a faculty’s own research activities, into the classrooms. This will generate research productivity and quality publications to increase the success rate in extramural funding, and pave the way to establish PhD and MD-PhD programmes in basic medical science.

Proposed solutions

The culture of research must be nurtured across society. This should start at the most basic level; as part of school curricula. Research is a complex process requiring critical thinking and strategic planning. Teaching students these skills would motivate them to be involved in research and provide them with a solid basis for the future.

The public must also be educated about research. There are many non-governmental organizations in the region, some of which are involved in supporting patients with particular diseases. In collaboration with the local governments and universities, these NGOs could provide education to the public about the importance of proper research and how it should be conducted.

The development of basic biomedical research can be encouraged by building on the strengths of the few areas where a critical mass of high-quality research already exists. This could be achieved by establishing regional collaborative groups for translational and clinical research.

These groups could then be used to launch meaningful investigator-initiated clinical trials and to forge partnership with the pharmaceutical industry. Regional incubators or centres of excellence are also needed to better manage resources and to attract investigators from abroad. They can also generate science-based innovations if partnerships with industry are established.

These centres require solid evaluation, auditing and quality assurance mechanisms. Based on track record, size and relative stability, the American University of Beirut Faculty of Medicine and Medical Center in Lebanon, the King Faisal Specialist Hospital and Research Center in Saudi Arabia, and other centers in the Gulf area (such as Kuwait Science Foundation or Qatar Foundation) could spearhead this programme with the goal of integrating others at a later stage. The initial centres can establish a network that allows mobility of researchers, students and technicians.

A vital step in propelling research is establishing a regional, cross-border institute for funding of biomedical research. This should be similar to the National Institute of Health in the US or the European Research Council, and be funded by private donors, governments and foundations. Funding should be merit-based and dependent on the ongoing quality of research.

Research productivity must be scientifically evaluated through a regional watchdog with a special focus on promoting original publications in high impact journals. This body can also determine initial funding of the centres of excellence and regularly evaluate them. As research is now evolving rapidly at a high rate, support mechanisms and government regulations should allow for rapid decisions, quick customs procedures and easy international contacts.

We propose the establishment of a think-tank at the highest regional level (for example the deans of certain medical schools and heads of research institutes in the region) to develop the potential structure for the regional funding agency described above. This group would then become the figurehead for persuading governments, foundations and the private sector to create a regional NIH-like structure for the region.

This is a priority and an essential step to put the region on the map in biomedical research. We believe that we have the resources and the brainpower, but we need the stimulus.

As Seneca said: it is not because things are difficult we do not dare, it is because we do not dare things are difficult.
