Researchers at University of Rhode Island Unveil Lab-on-Paper Test Capable of Multireagent Diagnostics: Could Enable ‘Diagnostics Without the Lab’ say Developers

New diagnostic capabilities could enable clinical laboratories to obtain multiple outcomes on single fluidic strip tests

Researchers at the University of Rhode Island (URI) have developed a paper-based microfluidic valve technology that some claim may revolutionize existing lateral-flow tests. There is the potential for this innovation to eventually enable pathology groups and medical laboratories to conduct a wide variety of complex medical diagnostics on single fluidic test strips, such as those used to diagnose pregnancy and strep throat, according to a university statement.

Testing Multiple Biomarkers Using a Single Test Strip

Fluidic test strips commonly in use today are generally capable of rendering only one result. However, by combining their new paper-based valve platform with standards strip tests, the URI research team has produced strip tests capable of answering more challenging medical questions.

The evolution of the new technology, dubbed “Lab-on-Paper,” follows the development of the team’s earlier “lab-on-a-chip” device, which the researchers began developing back in 2005. (more…)

New Medical Laboratory Test from Washington University School of Medicine Could One Day Replace the Popular PCR Assays Used by Many Pathologists

Called ‘ViroCap,’ this new diagnostic technology is able to discover more viruses in patient samples, as compared to PCR genome sequencing tests

It could be the ultimate multi-analysis medical laboratory test ever. Researchers at Washington University School of Medicine in St. Louis have developed a diagnostic test that they claim tests for any virus infecting people and animals.

The new test, called ViroCap, detects viruses that standard tests based on genome sequencing cannot, according to a university statement.

Viruses Make for a Popular Research Subject

Are virus tests going, well, viral? It was just a few weeks ago that Dark Daily reported on research at Howard Hughes Medical Institute (HHMI) aimed at unlocking virus detection beyond one pathogen at a time. (See Dark Daily, “Researchers at Howard Hughes Medical Institute Develop Blood Test That Reveals a Patient’s Viral History; Could Reduce Unnecessary Clinical Laboratory Testing,” December, 30, 2015.)

The HHMI research resulted in VirScan, an alternative to medical laboratory tests that test for specific viruses one at a time, and which can detect all diseases a patient has had over his or her lifetime, according to an HHMI news statement about the new technology. (more…)

UCLA Researchers Develop Lens-Free Smartphone Microscope, Pathologists May Be Able to Take the Clinical Pathology Laboratory Just About Anywhere

In a trial, the lens-free microscope invention from the UCLA California Nano Systems Institute enabled a board-certified pathologist to detect cancers and other cellular abnormalities at 99% accuracy

One of our favorite innovators is at it again, this time with a device that could eventually allow pathologists to use a device coupled with a smartphone to view cancer and other abnormalities at the cellular level.

At UCLA, Professor Aydogan Ozcan, Ph.D. is already well known for having invented attachments that use a smartphone’s camera to create a tiny, lens-free microscope. Now Ozcan, who is the Chancellor’s Professor of Electrical Engineering and Bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, has created an inexpensive smartphone device that produces holographic images of tissue samples that allow pathologists to view cancer and other abnormalities at the cellular level, according to a December 17, 2014, Science Translational Medicine (STM) article.

Synthetic Biologists Demonstrate Ability to Rapidly Create Cheap, Accurate In Vitro Diagnostics Tests That Could Eventually Help Pathologists Diagnose Disease

Wyss Institute develops prototype Ebola test in less than 12 hours with $20 in materials, perhaps paving the way for inexpensive paper-based diagnostic tests with a wide range of applications outside the medical laboratory

One goal of many synthetic biology researchers is to create in vitro diagnostic testing systems that produce results that are as accurate as those produced in today’s state-of-the-art clinical laboratories, yet are much cheaper to run because they incorporate low-cost materials, such as paper.

Recently, two teams of researchers worked to demonstrate how several synthetic biology methods, when combined with programmable paper-based diagnostic platform, could detect antibiotic-resistant bacteria and strain-specific Ebola virus. These findings were published in a peer-reviewed medical journal last fall.

Such cell-free circuits embedded in paper could be the breakthrough in synthetic biology that leads to pocketsize blotter tests that can detect such diseases as Ebola in the field.  Should this line of research be applied to clinical settings, pathologists and medical laboratory scientists could soon be processing bandages that change colors in the presence of certain bacteria, or examining paper-based clothing infused with diagnostic laboratory tests that react to bio-markers specific to a chronic disease patient’s condition.

New High-Tech Mobile Medical Laboratories Deployed by the U.S. Navy and a European Consortium Use Genetic Analysis to Get Rapid Diagnosis of Ebola

These genetic tests cut time to answer from days to a few hours, reducing the risk of exposing non-infected patients and improving outcomes for Ebola patients

In response to the continuing outbreak of Ebola in the West African countries of Guinea, Liberia, and Sierra Leone, more attention has been given to medical laboratory testing in these countries, along with a rush to develop diagnostic tests that can detect Ebola faster and more accurately without the need for state-of-the art clinical laboratories that are uncommon in those nations.The lack of even limited basic services in the region, such as electricity, hinders any attempt to install modern diagnostic facilities and clinical laboratories essential to controlling and preventing further spread of the disease. Another issue is the lack of trained pathologists, Ph.Ds., and clinical laboratory scientists to staff such labs in those nations.

One solution to this challenge, however, is for developed nations to provide mobile medical laboratories and hospital facilities. Such resources have been contributed by the United States, Canada, and several European countries. (more…)
