Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...
The widespread use of engineered nanoparticles (ENPs) in industrial applications and consumer products makes their release to the environment inevitable. Understanding the aggregation behavior of ENPs is crucial to understanding their fate, transport and toxicology in aquatic systems. This study investigated the comparability of experimentally-determined and model-estimated attachment efficiencies for...
Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are...
As nanoparticle (NP) research and development expands, the significance of NP biodistribution effects on toxicity increases. A reliable method for measuring NP biodistribution is critical. Hyperspectral Imaging (HSI) is capable of accurately quantitating NP biodistribution within embryonic zebrafish with incredibly high precision. Before HSI processing, the embryo must be sectioned...
Nanoparticles (NPs) are generally defined as particles <100 nanometers (nm) in size in one dimension. Despite increasing industrial usage of TiO2 NPs in sunscreens, cosmetics, and water remediation little is known of their environmental behavior. The primary goal of this research was to develop a rapid method for determining the...
Image-guided phototherapy is extensively considered as a promising therapy for cancer treatment. To enhance translational potential of this modality, we developed a single agent-based biocompatible nanoplatform that provides both real time near-infrared (NIR) fluorescence imaging and combinatorial phototherapy with dual photothermal and photodynamic therapeutic mechanisms. The developed theranostic nanoplatform consists...
Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...
In this work, continuous synthesis routes for binary nanoparticles using advantages of microchannel mixing (low diffusion distances and higher mass transfer) and fast heating rates provided by ultrasound induced heating are investigated. In addition, the application of silica nanoparticles in anti-reflective coatings on glass and understanding the structure property-performance correlation...
Nanoparticles, materials on a 10⁻⁹ meter size scale, are finding applications in
a variety of areas including catalysts, fuel and solar cells, biological labeling.
electronics and optoelectronic devices. Semiconductor nanoparticles are of particular
interest because of their size tunable properties resulting from quantum confinement
effects. Mass productions of monodisperse semiconductor...
Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...
