Investigating lipid corona formation onto polystyrene nanoparticles through fluorescence correlation spectroscopy
… on exposure of lipid vesicles to different polystyrene nanoparticles indicate possible formation of a lipid corona. Further study varying the nanoparticle charge and lipid vesicle fluidity can help elucidate the mechanism of lipid corona formation. Such work can provide insight into …

Photochromic Molecular Materials for the Controlled Organization of Nanoparticles
The displacement of polystyrene nanoparticles promoted by bulk azo mass transfer using interferential light illumination will be discussed. For this a variety of different push pull small azo molecules were synthesis and characterized, changing the polarity, hydrophobicity and bulky groups around …

Structural properties and phase behavior in colloidal suspensions
… system of silica microspheres and highly charged polystyrene nanoparticles. Computer simulations are employed to determine the effective microsphere– microsphere potential induced by the nanoparticles. From these simulations I am also able to determine the degree of nanoparticle adsorption on the …

Investigation of the absorptive potential of polymeric nanoparticles across the lungs and their development for efficient systemic delivery following pulmonary administration
… drug delivery of small molecules and proteins. Nanoparticles on the other hand have gained increasing interest in drug delivery due to the wide variety of advantages they possess that allow for temporal, spatial and targeted delivery of therapeutics that can be fine tuned for various …

Nanoparticle Engineering of Colloidal Suspension Behavior
We investigate the effects of highly charged nanoparticles on the phase behavior, structure, and assembly of colloidal microsphere suspensions. Specifically, by selectively tuning the electrostatic interactions between silica microspheres and polystyrene nanoparticles, we study the behavior of four …

An assessment of the biodistribution, persistence, and health impacts of microplastics and nanoplastics in fish
… on the biodistribution and persistence of polystyrene nanoplastic particles (50 nm and 500 nm) in zebrafish (Danio rerio). I found that exposure routes other than an oral exposure (i.e. dermal, respiratory) contribute to nanoplastic biodistribution, and that the nanoplastics were not …

Conformational investigations of a model polyzwitterion and its applications in oil recovery
In recent years, nanoparticles have demonstrated immense promise for the development of next generation technologies for subsurface reservoir characterization and oil recovery. Until now however, the scope of such nanoparticles has been limited due to the significant challenge of colloidal …

Design and Assembly of Block Copolymer-Modified Nanoparticles into Supracolloidal, Molecular Mimics
… when using isotropic building blocks (e.g. gold nanoparticles and polystyrene nanoparticles). Additionally, research studying the reversibility of nanoparticle assemblies is mostly limited to small-ligand-modified particles rather than polymer-modified nanoparticles. Polymers are particularly …
