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...

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...

Functionalization of carbon nanotubes for effective biosensing and potential biomedical applications

Creator:: Adenuga, Adeniyi A.
Abstract:: Since their discovery in the 1990s, the great potential of carbon nanotubes (CNTs) has made them a focus of many research endeavors, including their application as components of biosensors. The inherent chemical "inertness" of CNTs makes their application to biosensing a challenge. It is necessary to "decorate" their surfaces to...

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...

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...

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...

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 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...

Synthesis and characterization of novel stationary phases for small scale liquid chromatographic separations of proteins and nanoparticles

Creator:: Hutanu, Daniela
Abstract:: The emerging field of nanotechnology strictly requires the micro-scaling of the available separation technology and the design of novel devices for separations of molecules of interest. The separation of proteins and nanoparticles is challenging due to their relatively large size, non-specific adherence to surfaces and instability in many solvents. This...

From electrophoresis to dielectrophoresis: designing, fabricating, and evaluating an electroformed ratchet type microfluidic dielectrophoresis device

Creator:: Gonzalez, Carlos F.
Abstract:: Dielectrophoresis (DEP) is a separation method in which a non-uniform electric field is used to induce a dipole moment in a suspended particle. If the polarization of the particle is greater than that of the suspending medium, the particle will move towards the region of higher field strength (positive DEP);...
