    Abstract: Systems and methods related to optical nanosensors comprising photoluminescent nanostructures are generally described. Generally, the nanosensors comprise a photoluminescent nanostructure and a polymer that interacts with the photoluminescent nanostructure. In some cases, the interaction between the polymer and the nanostructure can be non-covalent (e.g., via van der Waals interactions). The nanosensors comprising a polymer and a photoluminescent nanostructure may be particularly useful in determining the presence and/or concentration of relatively small molecules, in some embodiments. In addition, in some instances the nanosensors may be capable of determining relatively low concentrations of analytes, in some cases determining as little as a single molecule. In some embodiments, the interaction between the analyte and the nanosensor (e.g., between the analyte and the photoluminescent nanostructure) can be reversible, which may allow, for example, for the reuse of a nanosensor after it has been exposed to an analyte.

    Abstract: The present disclosure is directed to materials, devices, and methods for resonant ambient thermal energy harvesting. Thermal energy can be harvested using thermoelectric resonators that capture and store ambient thermal fluctuations and convert the fluctuations to energy. The thermal resonators can include heat engines disposed between masses of varying sizes or diodes. The masses or diodes can be made of high and ultra-high effusivity materials to transfer thermal energy through the resonator and optimize power output. The masses or diodes of the resonator can be tuned to the dominant frequency of the temperature waveform to maximize the amount of energy being converted. The resonators can be added to existing structures to supply or generate power, and, in some embodiments, the structures themselves can be a mass of the thermal resonator. Methods for constructing and/or using such devices are also provided, as are methods for formulating ultra-high effusivity materials.

    Abstract: A composition for sensing an analyte can include a photoluminescent nanostructure (e.g. a carbon nanotube) complexed to a sensing polymer, where the sensing polymer includes a phenylboronic acid based polymer non-covalently bound to the photoluminescent nanostructure where the composition is capable of selectively binding the analyte, and the composition undergoes a substantial conformational change when binding the analyte. Separately, a composition for sensing an analyte can include a complex, where the complex include a photoluminescent nanostructure in an aqueous surfactant dispersion and a phenylboronic acid capable of selectively reacting with an analyte. The compositions can be used in devices and methods for sensing an analyte.
