Nonlinear effects in single-particle photothermal imaging

The Journal of Chemical Physics, 2023
Although photothermal imaging was originally designed to detect individual molecules that do not emit or small nanoparticles that do not scatter, the technique is now being applied to image and spectroscopically characterize larger and more sophisticated nanoparticle structures that scatter light strongly.

Micromanipulator by photothermal effect

SPIE Proceedings, 2003
An optical actuator has some interesting characteristics, such as no generation of magnetic noise and receiving the energy remotely. A novel micromanipulator using photothermal effect is proposed. It consists of three optical fibers. One end of the fiber is cut for a bevel and painted with black color.

Photothermal Transfection for Effective Nonviral Genome Editing

ACS Applied Bio Materials, 2021
The efficient nonviral delivery of nucleic acids into the cytoplasm is needed to fully realize the potential of gene therapy. Although cationic lipids and nanoparticles have been widely used to improve the intracellular delivery of nucleic acids, they suffer from cytotoxicity and poor endosomal escape, thus limiting the transfection efficacy.

Transmembrane MUC18 Targeted Polydopamine Nanoparticles and a Mild Photothermal Effect Synergistically Disrupt Actin Cytoskeleton and Migration of Cancer Cells.

Nano letters (Print), 2021
Transmembrane MUC18 is highly expressed on most metastatic cancers. Herein, we demonstrate that targeting MUC18 with polydopamine nanoparticles (PDA NPs) and a mild photothermal effect can completely cease the migration of melanoma and breast cancer ...

Nanosecond Photothermal Effects in Plasmonic Nanostructures

ACS Nano, 2012
Photothermal effects in plasmonic nanostructures have great potentials in applications for photothermal cancer therapy, optical storage, thermo-photovoltaics, etc. However, the transient temperature behavior of a nanoscale material system during an ultrafast photothermal process has rarely been accurately investigated.

Photothermal effects of laser tissue soldering

Physics in Medicine and Biology, 1999
Low-strength anastomoses and thermal damage of tissue are major concerns in laser tissue welding techniques where laser energy is used to induce thermal changes in the molecular structure of the tissues being joined, hence allowing them to bond together.

Spinel-Oxide-Integrated BiVO4 Photoanodes with Photothermal Effect for Efficient Solar Water Oxidation.

ACS Applied Materials and Interfaces, 2021
Spinel oxide materials have been widely used as oxygen evolution catalysts to enhance the photoelectrochemical (PEC) performance of photoelectrodes. Herein, we demonstrate that the water splitting efficiency of a photoanode can be further enhanced by ...

Detector effects in photothermal deflection experiments

Applied Optics, 2008
We report on the theoretical analysis of a detector type influence on the normal deflection signal in photothermal experiments. Two cases are examined. In the first, the quadrant photodiode was considered as the detector; in the second the signal from the position detector, which measures the central moment displacement of the probe beam, was analyzed.

Photothermal effects in mobile nanotweezers

2018 4th IEEE International Conference on Emerging Electronics (ICEE), 2018
Magnetically driven mobile plasmonic nanotweezers [1] are potential candidates for various device applications pertaining to optical manipulation which are otherwise difficult to achieve using existing techniques. When illuminated, plasmonic nanoantennas generate enhanced localized electric field which imparts mechanical gradient force to trap sub ...
