Abstract: A multiplexed widefield imaging method employs spatially focusing femtosecond infrared (IR) pulses and visible pulses delayed by a controlled temporal delay onto a sample stained with one or more chromophore to excite spontaneous emitted photoluminescence (PL) signals from the chromophores. The resulting PL signals are detected to generate PL images in which intensities of the PL signals are a function of optical frequencies of the IR and visible pulses and the temporal delay.

Abstract: Methods of fabrication and nano-sensor and nano-sensor array thereof are provided. A sensing electrode assembly can be patterned on a sacrificial layer of a substrate. The sensing electrode assembly can comprise a pair of contact pads and an electrode element coupled to and disposed between the pair of contact pads. The sensing electrode assembly can be formed on the patterned sensing electrode assembly. The sacrificial layer below a portion of the electrode element can be removed to obtain a suspended electrode element. The suspended electrode element can be oxidized at a first predetermined temperature to obtain a pair of electromigrated regions and a notch portion between the pair of the electromigrated regions. The notch portion can be used to detect a gaseous component in an ambient gas at a second predetermined temperature.

Abstract: Ruggedized luminescent nanoparticle tracers have luminescent nanoparticle cores coupled to a luminescent substrate. The substrate is a large-particle size phosphor, while the nanoparticles are photoluminescent quantum dots (QDs) whose emission spectra can be tuned based on their chemical composition, size, and fabrication (e.g., dopants). The QDs are encapsulated by a protective layer to form a nanoparticle core. The protective layer can shield the QDs from external environments that would otherwise damage the delicate QDs. The substrate is also encapsulated by a protective layer, and the protective layer of the nanoparticle core is coupled to the protective layer of the substrate via a molecular linker to form a tracer particle complex. The tracer particle complexes can be disposed in a silicate suspension for subsequent use.

Abstract: Methods and systems for stimulating and monitoring electrogenic cells are described. Some systems for stimulating electrogenic cells are based on the injection of electric currents into the cells via electrodes connected to the cells. Such stimulators may comprise an impedance element having an input terminal and an output terminal coupled to an electrode, and a voltage follower coupled between the input terminal and the output terminal of the impedance element, the voltage follower being configured to maintain a substantially constant voltage between the input terminal and the output terminal of the impedance element. The impedance element may comprise one or more switched capacitors at least in some embodiments. In some embodiments, the voltage follower may be implemented using a source follower.
