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...

Comprehensive, Low-Cost Wicking Microfluidic Analytical Devices for Clinical Diagnostics and Environmental Analysis

Creator:: Bandara, Gayan C.
Abstract:: Analytical techniques are utilized in a wide variety of applications. Traditionally, analytical measurements are achieved by trained personnel in a laboratory setting using expensive scientific instruments, which limits their applicability in resource-limited areas and point-of-care applications. Therefore, the concept of enabling these laboratory-based qualitative and quantitative assays in microfluidic device...

Electrospray Deposition of Discrete Nanoparticles: Studies on Pulsed-Field Electrospray and Analytical Applications

Creator:: Kremer, Matthew H.
Abstract:: Electrospinning and electrospray are both nano-scale material fabrication techniques, based on related phenomena of electrically charged fluid spray from a droplet of liquid. Material is dissolved in liquid, then a spray is generated by applying a high voltage, creating an electric field, between the fluid dispensing capillary and a grounded...

Effect of Plant Growth Regulator and Irrigation on Physiological and Harvest Maturity of Red Clover in Relation to Seed Quality

Creator:: Angsumalee, Duangporn
Abstract:: Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...

Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

Creator:: Chibwe, Leah
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...
