Gold nanolenses self-assembled by DNA origami

Here, we present a bottom-up approach to create plasmonic gold nanolenses (AuNLs), consisting of three differently-sized gold nanoparticles. The programmable technique of DNA origami is used to self-assemble...

Hyperspectral imaging of plasmon resonances for biosensing

Self-healing Functional Polymers: Optical Property Recovery of Conjugated Polymer Films by Uncatalyzed Imine Metathesis

The implementation of a self-healing functionality into materials has become a prevalent approach for materials which require long-term reliability. As of today, the restoration of mechanical properties...

Plasmon Enhanced Probe Spectroscopies – Current State of Theory and Experiment

Plasmon induced polymerization using a TERS approach: a platform for nanostructured 2D/1D material production

Plasmon-induced chemical reactions have recently attracted great attention as a promising method for high efficiency light-energy conversion and proved to be useful in a wealth of different domains of...

Performance limits of single nano-object detection with optical fiber tapers

Detecting the scattering process of individual nanoobjects using optical fibers is a promising fast, reliable and label-free detection scheme with strong potential in fields such as bioanalytics or disease...

Tuning light concentration inside plasmonic core-shell nanoparticles during laser irradiation

Computer modeling was carried out of the intensity distributions of optical (laser) radiation with wavelengths in the range of 180 - 540 nm concentrated inside spherical two-layered core-shell nanoparticles...

Biomimetic mineralization can increase the crystallinity of enamel and dentin

Objective. Since enamel is not capable of regeneration and dentin repair is dependent on odontoblasts and is directed towards the pulp, current treatment options aim to seal or fill these lesions. Previous...

Nanowire-based hybrid optical fibers: a platform for nonlinear light generation, nanoscale plasmonics and single nanoobject detection

Plasmonics for Nanoscale Light-matter Interaction

Well-designed plasmonic nanostructures can concentrate and control optical fields at nanometer scale [1] and provide stiff optical potential to manipulate nanoobjects [2]. Recently, it has been shown that...
