Bioengineering at LLNL
Analyzing Complex Biological Systems
Bioengineering at LLNL involves analysis of and intervention in complex biological systems with the aim of supporting the Lab’s missions. Bioengineering enables transformational solutions to counter biological threats and increase national resilience.
Bioengineering is highly multidisciplinary, with a long history of delivering solutions, from the 1980s’ High-speed Cell Sorter to the rapid antibody design in the face of COVID-19. As recent events have shown, biosecurity threats are evolving in new and unpredictable ways.
Our current bioengineering research and development is focused around four thematic areas:
- Sensors and devices
- Human organ models
- Artificial Intelligence and machine learning for precision medicine
- Biomaterials and biomanufacturing

Countering Biothreats with Nanoscale Solutions
Micro- and nanotechnologies enable exceptional new materials, devices and systems by exploiting performance characteristics only possible when engineering in the millimeter to nanometer length scale. Our expertise spans micro- and nanofabrication processes, microelectromechanical systems, electronics, photonics, micro- and nanostructures, nanosynthesis, implantable devices, and micro- and nanoactuators.
Recently, these nanoscale technologies played a key role in efforts to develop next-generation material to protect warfighters and first responders from biological and chemical warfare agents.
LLNL researchers and engineers Francesco Fornasiero, Ngoc Bui, Eric Meshot, Chiatai Chen, José Peña, and Kuang Jen Wu are pioneering the use of carbon nanotubes—with pores just a few nanometers wide—to create a base layer material that simultaneously provides biological threat protection and permeability to water vapor and which can be paired with a “smart” surface layer that guards against chemical agents. The team, with support from the Defense Threat Reduction Agency and the Laboratory Directed Research and Development Program, has already attained a crucial milestone in developing this next-generation protective garment by demonstrating that the proposed base layer is highly protective yet remarkably breathable.
Other carbon nanotube applications under study include biomimetic membranes with high throughput and high selectivity that can enable ultra-fast dialysis for patients.

Brain on a Chip
Some of our most significant advances are very tiny, such as a brain-on-a-chip device that records the neural activity of living brain cell cultures, enabling researchers to study the function of the human brain—outside of the body. Read Full Article
Brain on a Chip
Some of our most significant advances are very tiny, such as a brain-on-a-chip device that records the neural activity of living brain cell cultures, enabling researchers to study the function of the human brain—outside of the body.
In one of its first usages, LLNL scientists compared drug responses in the brains of rodents to drug responses of brain cells cultured in Lab-developed "brain-on-a-chip" devices — providing a critical first step to validating chip-based brain platforms.
Next, scientists expanded their efforts to modeling the temporal dynamics of neuronal cultures, paving the way to use the 3D brain-on-a-chip to screen therapeutic compounds and to develop human-relevant models of neuronal cultures for diseases and disorders such as traumatic brain injury — and perhaps find ways of re-establishing normal brain function in TBI patients.
Using a 3D microelectrode array platform, researchers keep thousands of human-derived neurons alive, networked, and communicating, while non-invasively recording their electrical activity. The device will advance research aimed at modeling disease or infections, drug discovery, and developing countermeasures for chemical or biological agent exposure.
