- Quantitative sizing of nano/microparticles with a tunable elastomeric pore sensorRobert Vogel
School of Mathematics and Physics, The University of Queensland, St Lucia QLD, Australia
Anal Chem 83:3499-506. 2011..Calculated particle diameters and coefficients of variation were shown to be in good agreement with both transmission electron microscopy and dynamic light scattering results...
- A variable pressure method for characterizing nanoparticle surface charge using pore sensorsRobert Vogel
School of Mathematics and Physics, The University of Queensland, St Lucia, QLD 4072, Australia
Anal Chem 84:3125-31. 2012..Results were of the same order as phase analysis light scattering (PALS) measurements. Unlike PALS results, the sequence of increasing zeta potential for different particle types agreed with conductometric titration...

Centre for Nanotechnology and Biomaterials, Level 5 East, Australian Institute for Bioengineering and Nanotechnology, The University of Queensland, St Lucia, QLD 4072, Australia
Mol Biosyst 5:826-31. 2009..The ammonia-treated supports were subjected to an Fmoc peptide synthesis procedure and successfully applied in a model microsphere-based flow cytometric immunoassay...
- Highly birefringent vaterite microspheres: production, characterization and applications for optical micromanipulationSimon J Parkin
University of Queensland, School of Mathematics and Physics, Queensland, Australia
Opt Express 17:21944-55. 2009..A hyperbolic model of the direction of the optical axis throughout the vaterite spherulite best fits the experimental data. Results from polarized light microscopy further confirm the hyperbolic model...
- Fluorescent organosilica micro- and nanoparticles with controllable sizeRobert Vogel
Nanotechnology and Biomaterials Centre, Australian Institute for Bioengineering and Nanotechnology, University of Queensland, Brisbane, QLD 4072, Australia
J Colloid Interface Sci 310:144-50. 2007..Finally, we suggest a coagulation model for the particle formation which significantly differs from conventional Stöber synthesis...
- Functionalized organosilica microspheres via a novel emulsion-based routeChris R Miller
Centre for Nanotechnology and Biomaterials, Department of Chemistry, The University of Queensland, St Lucia, QLD 4072, Australia
Langmuir 21:9733-40. 2005..These findings have implications for the production of functionalized solid supports for use in catalysis and biological applications, such as optically encoded carriers for combinatorial synthesis...
