Platinum Nanorod Electrode Arrays For Highly Sensitive And Initiative Brain-Machine Interfaces

The enhanced electrochemical activity of nanostructured materials is readily exploited in energy devices, but their utility in scalable and human-compatible implantable neural interfaces can significantly advance the performance of clinical and research electrodes. Traditional biologically inert noble metals such as Pt, Ir or IrPt – are preferential material choices for manufacturing nerve electrodes/ biomedical devices in clinical-relevant applications because of their biocompatibility and stability against corrosion, and because of their superior electrochemical properties compared to other material combinations. But despite these superior properties, the electrochemical interface impedance is not sufficiently low to enable recording minute potential fluctuations with low noise baseline or to efficiently inject charges across the interface without building large voltages across the interface and therefore consuming larger powers per pulse.  As a result, large electrodes are needed to compensate for this large impedance, but large electrodes compromise spatial resolution and specificity for recording and/or stimulation and limit the density and overall number of contacts. To increase the surface area and decrease the electrochemical impedance, nano-structures are often incorporated onto electrode surfaces to enhance their electrochemical properties. Prior work has successfully incorporated nano-structured Pt into electrodes, using electrochemical methods (electro-plating) , but these electrodes suffered from poor structural integrity and physical strength due to incorporation of electrochemical surfactants at the interface between nano-structured Pt and the underlying electrode. Furthermore, common approaches for the fabrication of nano-structured Pt are generally not monolithic and face additional challenges for translation to clinical practice whereas some are also problematic due to the residual of toxic ligand additives remaining after Pt alloy electro-deposition.

A Point Of Care Method To Detect Covid19 Infected And Immune Patients For Pennies

The emergence of a novel coronavirus disease (COVID-19) in late 2019 has caused a worldwide health and economic crisis.

Compact Ion Gun for Ion Trap Surface Treatment in Quantum Information Processing Architectures

Electromagnetic noise from surfaces is one of the limiting factors for the performance of solid state and trapped ion quantum information processing architectures. This noise introduces gate errors and reduces the coherence time of the systems. Accordingly, there is great commercial interest in reducing the electromagnetic noise generated at the surface of these systems.Surface treatment using ion bombardment has shown to reduce electromagnetic surface noise by two orders of magnitude. In this procedure ions usually from noble gasses are accelerated towards the surface with energies of 300eV to 2keV. Until recently, commercial ion guns have been repurposed for surface cleaning. While these guns can supply the ion flux and energy required to prepare the surface with the desired quality, they are bulky and limit the laser access, making them incompatible with the requirements for ion trap quantum computing.To address this limitation, UC Berkeley researchers have developed an ion gun that enables in-situ surface treatment without sacrificing high optical access, enabling in situ use with a quantum information processor.
