  • 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...

  • Design and Fabrication of a Polymeric Microfluidic Device for Automated

    Creator:
    Warner, Kelsie E.
    Abstract:
    Gene synthesis is an important tool in molecular biology. However, the current bench-top method of gene synthesis is a costly, time-intensive and reagent-consuming process. Lab-on-chip technology has many benefits over current bench top methods. Microchips consume smaller reagent volumes, are reusable and less expensive to make. This thesis explores the...

  • Magnetic bead detection with ferromagnetic resonance for use in immuno-biosensor application

    Creator:
    Ghionea, Simon
    Abstract:
    The objective of this thesis is to introduce and demonstrate a novel magnetic bead detector based on inductive detection at the ferromagnetic resonance (FMR) frequency for use in bio-sensing applications. Detection ability is demonstrated through theoretical arguments, numerical computer simulations, and experimental characterization of micro-fabricated detectors. The detector is composed...

  • Lead(II) Extraction with Electrospun Spiropyran Functionalized PMMA Nanofibers

    Creator:
    Fuchs, Brian K.
    Abstract:
    A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...

  • 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,...

  • Photoactuated Droplet Microfluidics

    Creator:
    Frederick, Ryan T.
    Abstract:
    A system of Photoactuated Droplet Microfluidics (PDM), in which a droplet of fluid is moved by way of the manipulation of the wettability of a spiropyran functionalized surface via irradiation with ultraviolet and visible light, was proposed. The photochromic behaviors of several species of spiropyran were studied and a procedure...

  • Centrifugal Partition Chromatography, Microfabrication, and a Smartphone-based Detection Platform : Analytical Chemistry from Preparative-scale Separation to Micro-scale Analysis

    Creator:
    Boonloed, Anukul
    Abstract:
    Analytical chemistry is an area of chemistry primarily focused on the study and use of instruments for separation, identification, and quantification of an analyte of interest. Specifically, separation science within analytical chemistry often refers to the process of dividing mixtures into their small component parts based on differences in their...

  • Label free biosensing with carbon nanotube transistors

    Creator:
    Leyden, Matthew R.
    Abstract:
    As electronics reach nanometer size scales, new avenues of integrating biology and electronics become available. For example, nanoscale field-effect transistors have been integrated with single neurons to detect neural activity. Researchers have also used nanoscale materials to build electronic ears and noses. Another exciting development is the use of nanoscale...

  • Magnetic particles for selective extraction of trace analytes in microfluidic devices

    Creator:
    Tennico, Yolanda H.
    Abstract:
    The development of micro total analysis systems (µTAS), also called “lab-on-a-chip”, or microfluidic analysis systems, is presented in this dissertation. Various research areas, covering subjects from magnetic particles synthesis to novel microchip fabrication techniques, are explored to develop a lab-on-a-chip system capable of performing magnetic bead-based bioassays. These devices are...
