Journal ArticleDOI
Characterizing and tracking single colloidal particles with video holographic microscopy
Sang-Hyuk Lee,Yohai Roichman,Gi-Ra Yi,Shin-Hyun Kim,Seung-Man Yang,Alfons van Blaaderen,Peter D. J. van Oostrum,David G. Grier +7 more
TL;DR: Digital holographic microscopy and Mie scattering theory are used to simultaneously characterize and track individual colloidal particles and measure their radius and refractive index.
Journal ArticleDOI
Nanonewton optical force trap employing anti-reflection coated, high-refractive-index titania microspheres
Anita Jannasch,Ahmet F. Demirörs,Ahmet F. Demirörs,Peter D. J. van Oostrum,Peter D. J. van Oostrum,Alfons van Blaaderen,Erik Schäffer +6 more
TL;DR: In this paper, an ultrastrong optical trap capable of operating with nanonewton optical forces by employing tailor-made high-refractive-index particles was demonstrated, which could lead to the development of highly efficient light-driven machines.
Journal ArticleDOI
Colloidal Analogues of Charged and Uncharged Polymer Chains with Tunable Stiffness
Hanumantha Rao Vutukuri,Ahmet F. Demirörs,Bo Peng,Peter D. J. van Oostrum,Peter D. J. van Oostrum,Arnout Imhof,Alfons van Blaaderen +6 more
TL;DR: Yanking the chain: a general method for the preparation of colloidal analogues of polymer chains was developed, which can be tuned by applying electric fields in combination with their subjection to simple linkage-forming procedures.
Journal ArticleDOI
Limiting the valence: advancements and new perspectives on patchy colloids, soft functionalized nanoparticles and biomolecules
Emanuela Bianchi,Emanuela Bianchi,Barbara Capone,Barbara Capone,Ivan Coluzza,Lorenzo Rovigatti,Peter D. J. van Oostrum +6 more
TL;DR: In this article, a review of systems characterized by limited bonding valence, from patchy colloids of new generation to polymer-based functionalized nanoparticles, DNA-based systems and proteins, and describe how the interaction patterns of the single building blocks can be designed to tailor the properties of the target final structures.
Journal ArticleDOI
Sequence controlled self-knotting colloidal patchy polymers.
TL;DR: An experimentally realizable model for the design of chains with controllable topological properties is introduced, paving the way to applications in the design and synthesis of active materials and novel carriers for drugs delivery.
