Correlative microscopy of single self-assembled nanorod dimers for refractometric sensing

Michael A. Beuwer, Peter Zijlstra* Single metallic particles and dimers of nanospheres have been used extensively for sensing, but dimers of particles provide attractive advantages because they exhibit multiple modes that can be tuned by the dimer geometry. Here, we employ correlative microscopy of single self-assembled dimers of gold nanorods to study their performance as […]

Imaging and Localization of Single Emitters near Plasmonic Particles of Different Size, Shape, and Material

Frank Bloksma, Peter Zijlstra* Colloidal plasmonic materials are increasingly used in biosensing and catalysis, which has sparked the use of super-resolution localization microscopy to visualize processes at the interface of the particles. We quantify the effect of particle–emitter coupling on super-resolution localization accuracy by simulating the point spread function (PSF) of single emitters near a […]

Research paper published in JPC Letters

DOI: doi.org/10.1021/acs.jpclett.0c00155 Yuyang Wang, Matěj Horáček, and Peter Zijlstra Plasmon resonances have appeared as a promising method to boost the fluorescence intensity of single emitters. However, because research has focused on the enhancement at low excitation intensity, little is known about plasmon–fluorophore coupling near the point where the dye saturates. Here we study plasmon-enhanced fluorescence […]

Dynamic single-molecule counting for the quantification and optimization of nanoparticle functionalization protocols DOI: doi.org/10.1039/C9NR10218C Matěj Horáček,  Dion J. Engels, Peter Zijlstra Applications of colloidal particles in the fields of i.e. biosensors, molecular targeting, or drug-delivery require their functionalization with biologically active and specific molecular ligands. Functionalization protocols often result in a heterogeneous population of particles with a […]
