  • Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

    Creator:
    Alemu, Yagenetfere A.
    Abstract:
    The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

  • Carbon Nanodots as Biolabels for Fluorescence Immunoassays

    Creator:
    Wu, Yuanyuan
    Abstract:
    There has been a tremendous growth in interest in carbon nanodots (C-dots) in the past several years. As a nascent nanomaterial, C-dots have shown great promise in applications that benefit from their superior water dispersibility, low toxicity, non-blinking fluorescent output, chemical and biological compatibility, ease of functionalization and resistance to...

  • Transport in silicon metal oxide semiconductor quantum dots

    Creator:
    Gunther, Allen David
    Abstract:
    Herein, a program of research is detailed related to transport through the Si metal oxide semiconductor (MOS) quantum dots fabricated in a process flow compatible with modern ULSI (ultra large scale integrated circuit). Silicon quantum dots were fabricated by placing split gates within a MOSFET structure. Quantum dots of several...

  • Polymeric submicron optical ion-selective sensors

    Creator:
    Bychkova, Valeriya
    Abstract:
    Ion-selective polymeric optical sensors – ion optodes – are a promising alternative to ion-selective electrodes and fluorescent dyes for analytical and biological applications, e.g. extra- and intracellular measurements. They are non-toxic, highly selective robust probes for ionic fluxes monitoring. A large-scale fabrication of ion optodes using a solvent displacement method...

  • Detection techniques for biomolecules using semi-conductor nanocrystals and magnetic beads as labels

    Creator:
    Chatterjee, Esha
    Abstract:
    Continued interest in the development of miniaturized and portable analytical platforms necessitates the exploration of sensitive methods for the detection of trace analytes. Nanomaterials, on account of their unique physical and chemical properties, are not only able to overcome many limitations of traditional detection reagents but also enable the exploration...

  • Improvements in synthesis and response techniques of ion-selective sensors

    Creator:
    Pylypiuk, Nataliia
    Abstract:
    Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...
