Increased stability in self-healing polymer networks based on reversible Michael addition reactions

A reversible thiol-ene click reaction is utilized to design novel self-healing polymers. These materials are based on a new methacrylate monomer featuring a benzylcyanoacetamide derivative, which is copolymerized...

Nanofilm-induced spectral tuning of third harmonic generation

Intermodal third-harmonic generation using waveguides is an effective frequency conversion process due to the combination of long interaction lengths and strong modal confinement. Here we introduce the...

Endoscopic fiber probe for nonlinear spectroscopic imaging

We present a compact multimodal fiber probe that enables the simultaneous recording of nonlinear imaging modalities like coherent anti-Stokes Raman scattering (CARS), second harmonic generation (SHG),...

Rapid detection of Clostridium species by applying a portable PCR chip

Increased Charge Separation Rates with Increasing Donor-Acceptor Distance in Molecular Triads: the Effect of Solvent Polarity

Distance-dependent electron transfer in donor–spacer–acceptor systems is accepted to occur via two distinct mechanisms, that is, by coherent superexchange or incoherent hopping. In general, the rate...

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...
