Biological engineer Paul Blainey creates new tools to advance biomedical research

Microfluidics — the technology of manipulating small levels of fluid through channels — has-been trusted in fields including genomics, in which this has assisted make it possible for high-speed sequencing. Previously, Paul Blainey started initially to ask yourself why microfluidics was not used for medication evaluating, another application that needs analyzing large sums of examples rapidly.

That question led him and his students to build up a new form of microfluidics system by which droplets are sealed within tiny wells, beating the situation of drug leakage which had stymied past efforts. This system worked well for screening drugs, but inaddition it ended up being ideal for many other programs, far beyond exactly what Blainey had initially envisioned.

“That’s the things I favor about science — you could have a thought about how comen’t microfluidics do even more for biochemistry, and after that you develop a thing that works out to own every one of these truly interesting utilizes and applications that nobody thought,” says Blainey, a member regarding the wide Institute of MIT and Harvard and a recently tenured associate professor into the division of Biological Engineering.

Blainey’s lab takes a wide-ranging approach to resolving technical problems, leading to the development of numerous cutting-edge resources over the past many years, with applications in areas from genomics to diagnostics and drug development. He credits his pupils with helping produce ideas for unique technologies, and pursuing alternate guidelines until they find something that works well.

“The significant research guidelines and technology systems that lab is renowned for these days arrived on the scene for this procedure where in fact the students or I had a crazy idea, then the laboratory performed about it, with all the current twists and turns along the way,” he says.

Attracted to manufacturing

Growing up in Seattle, the child of the phone business professional and a nursing professor, Blainey had a all-natural affinity for engineering. “I became always that kid who was into building designs,” he recalls. But he started his educational job into the sciences, majoring in chemistry and mathematics at the University of Washington. He continued to make a PhD in physical chemistry at Harvard University, but while seeking his levels, he had been drawn to the facets of technology most closely related to manufacturing.

“i truly liked analytical biochemistry, which can be like an engineering discipline as it’s focused on instrumentation, measurement, additionally the quantitative areas of biochemistry,” he states.

After finishing his PhD, he decided to go to Stanford University to your workplace like a postdoc inside laboratory of Stephen Quake, a teacher of bioengineering. Indeed there, he worked with one of the primary high-speed, next-generation genome sequencing machines set up in a scholastic lab, in 2007.

“The outcome ended up being that we discovered sequencing technology and genomics, we discovered some bacterial genetics, we learned microfluidic technology, and I truly started to appreciate just how these exact things could play together,” Blainey claims.

At Stanford, he performed single-cell genome sequencing of environmental microbes, but he wished to turn their research focus toward biomedicine and learning human being cells, so he applied for a professors place at wide Institute. Before coming for his meeting, he believed he’d like living on the western Coast, but their trip to MIT changed their head.

“Despite having been at Harvard for graduate school, I knew very little in regards to the wide and very little about MIT,” he states. “I took the trip to Boston, which exceeded my expectations. The clinical and collaborative potential in the Broad Institute and surrounding establishments hopped on so demonstrably.”

When Blainey signed up with the Broad Institute, he in addition joined MIT’s division of Biological Engineering, renewing his longstanding curiosity about engineering. He established their lab using the goal of developing biotechnologies might strongly influence biomedical study and be generally disseminated.

“We had been enthusiastic about distinguishing opportunities to develop technology that could fill vital gaps within the life technology analysis profile,” he says. “We had the chance to talk to folks, see what the requirements were, see where biological research had been well-served by technology, and attempt to discover gaps which may overlap with your toolkit or new stuff we could create.”

Completing the spaces

One location in which Blainey saw a need for brand new technology was at testing prospective medication compounds. Among big difficulties in evaluating medications is making sure there clearly was an adequate amount of each substance to try it against a wide array of solitary cells. Researchers weren’t making use of microfluidics to help with these displays because medicine particles tend to drip out from the little droplets utilized in microfluidic products.

Among Blainey’s graduate pupils, Tony Kulesa, came up with a notion for the brand new way to resolve the difficulty, that has been to seal nanoliter droplets into a range of little wells around microfluidic processor chip. This stopped the medicines from leaking out, and enabled large-scale screens. 

This technology turned out to be very helpful for screening individual medicines also combinations of medications. Inside a report posted in 2018, the researchers revealed that this system could possibly be always determine compounds that help present antibiotics to your workplace better. The wide Institute happens to be establishing a center financed by the National Institute of Allergy and Infectious Diseases, where this platform will be familiar with research additional substances with antimicrobial task.

It later turned out that system might be useful for multiple experiments that involve testing the interactions of many different combinations of cells or molecules.

In one single task, Blainey worked with Jeff Gore, an MIT associate teacher of physics, to combine various strains of bacteria in droplets and study how they communicate with one another. He additionally tried it to make a new type of a CRISPR-based diagnostic technology known as Sherlock, formerly developed by some other labs during the Broad Institute. The droplet array system allows the test is done on numerous examples at the same time, also to simultaneously test for most different diseases.

Another technique Blainey recently developed, called optical pooled assessment, allows researchers to examine just how genetics impact complex cellular procedures, with spatial and temporal resolution. This technique, described in Cell on Oct. 17, integrates large-scale pooled hereditary screens with image-based analysis of cellular behavior.

Blainey’s lab will continue to search for brand-new areas which could benefit from technological innovation, while also following potential programs for the resources they have developed.

“Our antennae are sensitive to these general types of technical obstacles where when you can develop robust and basic solutions, it certainly unlocks countless material. But we’re also excited to dig further into the biology making use of resources we’ve currently developed,” he says. “It’s slightly like grassroots politicking — you probably have to get online and pound the pavement and show exactly how it can be used in different methods.”
