Characterization of the cytotoxicity and imaging properties of secondharmonic nanoparticles

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

We develop second-harmonic nanoparticles as the contrast agents for cell imaging. Second-harmonic nanoparticles show promise as cell imaging probes due to their non-bleaching, non-blinking, and coherent signal. Nanoparticles of noncentrosymmetric crystal s ...

SPACE: the spectroscopic all-sky cosmic explorer

Yi Wang, Stewart Cole, Jean-Paul Richard Kneib, Herbert Shea, Rachel Grange

We describe the scientific motivations, the mission concept and the instrumentation of SPACE, a class-M mission proposed for concept study at the first call of the ESA Cosmic-Vision 2015–2025 planning cycle. SPACE aims to produce the largest three-dimensio ...

Imaging with second-harmonic radiation probes in living tissue

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu, Thomas Jean Victor Marie Lanvin

We demonstrate that second-harmonic radiation imaging probes are efficient biomarkers for imaging in living tissue. We show that 100 nm and 300 nm BaTiO3 nanoparticles used as contrast markers could be detected through 50 mu m and 120 mu m of mouse tail ti ...

Nonlinear optical properties of core-shell nanocavities for enhanced second-harmonic generation

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

A nonlinear optical plasmonic core-shell nanocavity is demonstrated as an efficient, subwavelength coherent light source through second-harmonic generation. The nonlinear optical plasmonic nanocavity incorporates a noncentrosymmetric medium, which utilizes ...

Three-dimensional harmonic holographic microcopy using nanoparticles as probes for cell imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

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 marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocry ...

Second harmonic generation from nanocrystals under linearly and circularly polarized excitations

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

We study second harmonic generation (SHG) from noncentrosymmetric nanocrystals under linearly polarized (LP) and circularly polarized (CP) excitations. Theoretical models are developed for SHG from nanocrystals under both plane-wave and focused excitations ...

Digital phase conjugation of second harmonic radiation emitted by nanoparticles in turbid media

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

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 nanoparticle. A SHG active nanoparticle inside a turbid medium was excited at the fu ...

Plasmonic heating with near infrared resonance nanodot arrays for multiplexing optofluidic applications

Rachel Grange

In this work, we show local laser-induced heating in fluids with gold nanodot arrays prepared by electron-beam lithography that cover resonances in the near infrared spectral range from 750 nm to 880 nm. We utilize two approaches to demonstrate thermal eff ...

Bioconjugation of barium titanate nanocrystals with immunoglobulin G antibody for second harmonic radiation imaging probes

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

The second harmonic generation (SHG) active nanocrystals have been demonstrated as attractive imaging probes in nonlinear microscopy due to their coherent, non-bleaching and non-blinking signals with a broad flexibility in the choice of excitation waveleng ...

Imaging through turbid layers by scanning the phase conjugated second harmonic radiation from a nanoparticle

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu, Grégoire Pierre Jean Laporte

We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same r ...
