New microfluidic device delivers mRNA nanoparticles a hundred times faster
An etched silicon and glass wafer on a surface with a quarter beside it for scale.

The researchers’ new platform technology, called Very Large Scale Microfluidic Integration, allows tens of thousands of microfluidic units to be incorporated into a single three-dimensionally etched silicon-and-glass wafer. (Image: Penn Engineering Today)

New microfluidic device delivers mRNA nanoparticles a hundred times faster

With a “liquid assembly line,” Penn researchers have produced mRNA-delivering-nanoparticles significantly faster than standard microfluidic technologies.

Becoming a bioengineer, both at home and on campus
electrocardiogram modules This year, the electrocardiogram (ECG) module was redesigned in a way that allowed both in-person and at-home students to create a device to measure their heart rate. These types of innovations also provide new ways to think about STEM education and distance learning more broadly. (Image: Bioengineering Educational Lab)

Becoming a bioengineer, both at home and on campus

This spring, the Bioengineering Modeling, Analysis, and Design lab was able to safely resume in-person instruction while adapting its curriculum to keep remote learners engaged.

Science vs science: The contradictory fight over whether electromagnetic hypersensitivity is real

Science vs science: The contradictory fight over whether electromagnetic hypersensitivity is real

Electromagnetic fields are everywhere, and especially so in recent years. To most of us, those fields are undetectable. But a small number of people believe they have an actual allergy to electromagnetic fields. Ken Foster, a professor emeritus of bioengineering, has heard these arguments before.  “Activists would point to all these biological effects studies and say, ‘There must be some hazard’; health agencies would have meticulous reviews of literature and not see much of a problem.”

This L.A. start-up is building tiny injectable robots to attack tumors

Marc Miskin of the School of Engineering and Applied Science commented on a new startup that is developing remote-control medical microrobots. “I would give them a lot of credit for figuring out a space where they can make an impact and justify how they’ll be competitive with traditional pharmaceutical approaches,” he said.

New bioprinting technique allows for complex microtissues
A rendering of tissue forming a hydrogel in three steps.

The researchers’ new technique allows clumps of cells to be picked and placed into a self-healing hydrogel, which holds them in complex spatial arrangements as they grow together. Once the tissue model is formed, the hydrogel is washed away. (Image: Penn Engineering Today)

New bioprinting technique allows for complex microtissues

Researchers at the School of Engineering and Applied Science have demonstrated a new bioprinting technique that enables the bioprinting of spatially complex, high-cell-density tissues.
