Using advanced fabrication techniques, engineers at the University of California San Diego have built a nanosized device out of silver crystals that can generate light by efficiently “tunneling” electrons through a tiny barrier. The work brings plasmonics research a step closer to realizing ultra-compact light sources for high-speed, optical data processing and other on-chip applications.

By doping alumina crystals with neodymium ions, engineers at the University of California San Diego have developed a new laser material that is capable of emitting ultra-short, high-power pulses—a combination that could potentially yield smaller, more powerful lasers with superior thermal shock resistance, broad tunability and high-duty cycles.

A new discovery in how heart muscles maintain their shape in fruit flies sheds light on the crucial relationship between cardiac function, metabolism, and longevity. Researchers from the University of California San Diego discovered that maintaining high levels of the protein vinculin—which sticks heart muscle cells to one another—confers health benefits to fruit flies. Their work shows that fruit flies bred to produce 50 percent more vinculin enjoyed better cardiovascular health and lived a third of their average life span longer.

A team led by the University of California San Diego has developed a chip that can detect a type of genetic mutation known as a single nucleotide polymorphism (SNP) and wirelessly send the results in real time to an electronic device. The chip is at least 1,000 times more sensitive at detecting an SNP than current technology. The advance could lead to cheaper, faster and portable biosensors for early detection of genetic markers for diseases such as cancer.

Graphene electrodes could enable higher quality imaging of brain cell activity thanks to new research by a team of engineers and neuroscientists at the University of California San Diego.
The researchers developed a technique, using platinum nanoparticles, to lower the impedance of graphene electrodes by 100 times while keeping them transparent. In tests on transgenic mice, the electrodes were able to record and image neuronal activity (calcium ion spikes) at both the macroscale and single cell levels.

Renkun Chen, a professor of mechanical and aerospace engineering at the University of California San Diego, has received a $1.18 million dollar award from the U.S. Department of Energy Solar Energy Technologies Office to develop technology that can advance next-generation concentrating solar power (CSP) systems. The project is aimed at developing an ultra-sensitive infrared camera that can rapidly measure and monitor heat transfer in CSP plant materials and assess their performance over decades of use.

Engineers at the University of California San Diego have developed tiny ultrasound-powered robots that can swim through blood, removing harmful bacteria along with the toxins they produce. These proof-of-concept nanorobots could one day offer a safe and efficient way to detoxify and decontaminate biological fluids.

Engineers have developed a tiny, ultra-low power chip that could be injected just under the surface of the skin for continuous, long-term alcohol monitoring. The chip is powered wirelessly by a wearable device such as a smartwatch or patch. The goal of this work is to develop a convenient, routine monitoring device for patients in substance abuse treatment programs.

Researchers have developed a stretchable, flexible patch that could make it easier to perform ultrasound imaging on odd-shaped structures, such as engine parts, turbines, reactor pipe elbows and railroad tracks—objects that are difficult to examine using conventional ultrasound equipment. The ultrasound patch is a versatile and more convenient tool to inspect machine and building parts for defects and damage deep below the surface.
