  • 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...

  • Design, characterization, and application of spectrometers for determination of low-level dissolved oxygen with small-volume sampling methodology

    Creator:
    Cakin, Defne
    Abstract:
    New analytical methods and instrumentation were developed for the determination of dissolved oxygen (DO) at low concentrations in water. The methods were based on monitoring the absorbance increase due to the oxidation of reduced indigo carmine (IC) by oxygen in the sample in different types of spectrometer cells. Spectrophotometer cells...

  • Displacement-based fluorescent microRNA biosensors : design principles and analytical metrics

    Creator:
    Larkey, Nicholas E.
    Abstract:
    One post-transcriptional mechanism that regulates the progression of cancer and other diseases involves small 22-23 nucleotide sequences called microRNA (miR). Early detection of small changes in concentration of these biomarkers holds potential to diagnose diseases at their earliest stages. Use of current nucleic-acid based biosensors, like molecular beacons, for in...
