Imagine a world where medical treatments navigate directly to diseased cells, electronics generate virtually no heat, and materials possess supernatural strength. This isn't science fiction—it's the reality being engineered at scales so small that thousands of these structures could line a single human hair.
At the Center for Nanoscale Science and Engineering (CeNSE), multidisciplinary teams of scientists are mastering manipulation at the atomic and molecular level, creating materials and devices with extraordinary properties not found in nature.
CeNSE represents a collaborative hub where physics, chemistry, biology, and engineering converge to push technological boundaries. The center serves as both a research facility and an idea incubator, providing cutting-edge instrumentation to academic and industrial users across diverse fields including medicine, electronics, energy, and even art 4 .

In healthcare, CeNSE researchers are engineering nanoparticle-based drug delivery systems designed to transport therapeutic agents directly to diseased cells while sparing healthy tissue 1 .
This targeted approach could dramatically reduce side effects associated with conventional treatments like chemotherapy.
As traditional electronics approach physical limitations, CeNSE investigators are pioneering post-silicon technologies. Research spans from nanotube FETs that could extend Moore's Law to molecular electronics 1 .
In parallel, nanoscale photonics work explores using light rather than electricity for information transfer.
The integration of specialized nanotemplates facilitates creation of sophisticated gas sensors and electronic components with tailored responses to environmental stimuli 1 .

Traditional electronic devices face a fundamental efficiency problem: as electrons flow through conductors, they encounter resistance that converts valuable energy into wasted heat. This thermal loss not only reduces battery life but also limits how densely components can be packed without overheating.
Recently, researchers at the University of Michigan—in work representative of the cutting-edge science relevant to centers like CeNSE—developed a revolutionary approach by creating a nanoengineered optoexcitonics (NEO) switch that harnesses excitons instead of electrons 3 .
Researchers chose a monolayer of tungsten diselenide (WSe2) due to its exceptionally high exciton binding energy, which keeps excitons stable even at room temperature 3 .
The WSe2 layer was precisely placed on a custom-designed silicon dioxide (SiO2) nanoridge with precisely engineered tapers. This nanostructure creates directional forces that guide excitons along predetermined paths 3 .
The team leveraged interactions between light-emitting and "dark" excitons to generate a quantum effect that pulls the entire exciton population, enabling transport that is both faster and covers longer distances 3 .
The NEO switch achieved remarkable performance metrics, demonstrating a 66% reduction in energy losses compared to conventional electronic switches while achieving an on-off ratio of 19 dB at room temperature 3 .
Perhaps even more impressively, the design enabled excitons to travel 400% farther than in previous exciton guides, overcoming a major limitation that had hampered practical application of excitonic systems 3 .
| Parameter | Traditional Electronic Switches | Nanoengineered Excitonic Switch |
|---|---|---|
| Energy Loss | High (significant heat generation) | 66% reduction |
| On-Off Ratio | ~19 dB (best available) | >19 dB |
| Operating Temperature | Room temperature | Room temperature |
| Signal Carrier | Electrons | Excitons |
| Transport Distance | Limited by resistance | 400% improvement over previous exciton guides |
This breakthrough demonstrates how tailored structural design at the nanoscale can control quantum phenomena for practical applications. The ability to efficiently guide neutral particles opens possibilities for an entirely new class of devices that bridge the gap between electronic and photonic technologies.
The pioneering work at centers like CeNSE relies on specialized instruments and materials that enable manipulation and characterization at atomic scales. These tools form the foundation of discovery across diverse nanotechnology domains.
