In working with nanoparticles, researchers still face two fundamental challenges: how to
fabricate the nanoparticles with controlled size and shape and how to characterize them. In …

Optical waveguiding phenomena found in bioinspired chemically synthesized peptide
nanostructures are a new paradigm which can revolutionize emerging fields of precise …

Nonlinear photon conversion is a fundamental physical process that lies on the basis of
many modern disciplines, from bioimaging and theranostics in nanomedicine to material …

We demonstrate focusing coherent light on a nanoparticle through turbid media based on
digital optical phase conjugation of second harmonic generation (SHG) field from the …

Nonlinear optical nanocrystals have been recently introduced as a promising alternative to
fluorescent probes for multiphoton microscopy. We present for the first time a complete …

In this tutorial I analyze the polarization-dependent properties of different optical contrasts
widely used today in imaging, applied to biology and biomedical diagnostics. I derive the …

Luminescent markers play a key role in imaging techniques for life science since they
provide a contrast mechanism between signal and background. We describe a new type of …

Orientation of nanoscale objects can be measured by examining the polarized emission of
optical probes. To retrieve a three-dimensional (3D) orientation, it has been essential to …

For the next generation of integrated optical circuits one-dimensional (1D) multiresponsive
materials with tunable nonlinear optical (NLO) properties are highly desired.[1] While …

The pioneering experiments in linear spectroscopy were performed using flames in the
1800s, but nonlinear optical measurements had to wait until lasers became available in the …
