The field of plasmonics is driven by the investigation of the interaction between the
electromagnetic (EM) field (light) and metal nanostructures. In particular, noble metal …

By electrodeposition and galvanic replacement reaction, we developed a facile, time-saving,
cost-effective, and environmentally friendly, two-step synthesis route to obtain a controllable …

Optical second-and third-harmonic generations have attracted a lot of attention in the
biomedical imaging research field recently due to their intrinsic sectioning ability and …

Second-harmonic generation (SHG) microscopy began to emerge as a high-resolution
optical imaging modality in the late 1990s, about 10 years after two-photon excited …

Higher harmonic-generation, including second harmonic generation and third harmonic
generation, leaves no energy deposition to the interacted matters due to its virtual-level …

We recorded one-photon excited fluorescence (1PEF) and two-photon excited fluorescence
(2PEF) spectra of purified keratin from human epidermis, and determined the action cross …

Abstract Three-dimensional (3D) cell cultures are important tools in cell biology research
and tissue engineering because they more closely resemble the architectural …

In vivo visualization of human skin aging is demonstrated using a Cr: Forsterite (Cr: F) laser-
based, collagen-sensitive second harmonic generation (SHG) microscope. The deep …

Optical microscopy is a valuable tool for in vivo monitoring of biological structures and
functions because of its non-invasiveness. However, imaging deep into biological tissues is …

Third-harmonic generation (THG) microscopy provides images of unstained biological
samples based on spatial variations in third-order nonlinear susceptibility, refractive index …
