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 […]
These positions have been filled. We are excited to announce that two PhD vacancies are available for application at the molecular plasmonics group in Eindhoven University of Technology. PhD position on correlative super-resolution microscopy of nanoparticles (V34.4269) PhD position on responsive nanoplasmonic sensors (V34.4270) The two PhD positions are supported by The SuperCol Innovative Training […]
Original post can be found on the TU/e website. Peter Zijlstra recently received a Consolidator Grant of € 2 million from the European Research Council (ERC). He is using the grant for his research into making protein interactions visible by means of gold particles. In this way he hopes to be able to unravel how […]
Peter will present the group’s most recent results at the Gordon Research Conference in Hong Kong on Plasmonically Powered Processes! For the conference’s full program see https://www.grc.org/plasmonically-powered-processes-conference/2019/.
We are happy that our ITN grant called SuperCol was awarded! This is an international training network funded by the European Union and is coördinated by Peter. The network will train a new generation of creative, entrepreneurial and innovative early-stage researchers. Several academic institutes and industrial partners across Europe will collaborate to train a new […]
Plasmon Rulers as a Probe for Real-Time Microsecond Conformational Dynamics of Single Molecules Emiel W.A. Visser, Matěj Horáček, and Peter Zijlstra DOI: 10.1021/acs.nanolett.8b03860 Biopolymers such as DNA, RNA and proteins exploit conformational changes to modulate their function. Although state-of-the-art single-molecule approaches enable identification of conformational states, the transition path and metastable intermediates often remain elusive […]
Plasmon-Enhanced Single-Molecule Enzymology Yuyang Wang and Peter Zijlstra DOI:10.1021/acsphotonics.8b00327 We present a numerical study on plasmon-enhanced single-molecule enzymology. We combine Brownian dynamics and electromagnetic simulations to calculate the enhancement of fluorescence signals of fluorogenic substrate converted by an enzyme conjugated to a plasmonic particle. We simulate the Brownian motion of a fluorescent product away from the active […]
The Europtrode XIV in 2018 was held on 25-28th March in Naples, Italy. Rachel’s talk on plasmonic biosensors won The Paper Award. Congratulations to Rachel! The Best Paper Award is given to the best presentation (poster, oral, or invited speaker presentation) as voted by the conference attendees. It is sponsored by the journal Sensors.
Spatially Resolved Sensitivity of Single-Particle Plasmon Sensors Michael A. Beuwer, Bas van Hoof, and Peter Zijlstra DOI:10.1021/acs.jpcc.8b00849 The high sensitivity of localized surface plasmon resonance sensors to the local refractive index allows for the detection of single-molecule binding events. Though binding events of single objects can be detected by their induced plasmon shift, the broad […]
