Combined Photothermal Lens and Photothermal Mirror Characterization of Polymers

Applied Spectroscopy, 2014
We propose a combined thermal lens and thermal mirror method as concurrent photothermal techniques for the physical characterization of polymers. This combined method is used to investigate polymers as a function of temperature from room temperature up to 170 °C. The method permits a direct determination of thermal diffusivity and thermal conductivity.

Thermal effects in photothermal spectroscopy and photothermal imaging

Journal of Applied Physics, 1983
The effect of thermal parameters on photothermal spectroscopy and photothermal imaging for certain types of spatially heterogeneous samples has been studied. Results have been obtained for both photoacoustic and photothermal deflection modes of detection. Specific attention has been paid to optical saturation in samples whose properties exhibit gradual

A Dual‐Targeted Organic Photothermal Agent for Enhanced Photothermal Therapy

Angewandte Chemie International Edition, 2018
AbstractThe development of highly effective anticancer drugs that cause minimal damage to the surrounding normal tissues is a challenging topic in cancer therapy. Herein, we demonstrate a dual‐targeted organic molecule that functions as a photothermal agent by actively targeting tumor tissue and mitochondria to selectively kill cancer cells.

Cu7.2S4 nanocrystals: a novel photothermal agent with a 56.7% photothermal conversion efficiency for photothermal therapy of cancer cells

Nanoscale, 2014
Copper sulphides, as a novel kind of photothermal agent for photothermal therapy (PTT) of cancer cells, have attracted increasing attention in recent years due to good photostability, synthetic simplicity, low toxicity and low cost. However, the unsatisfactory photothermal conversion efficiency of copper sulphides limits their bioapplication as PTT ...

Photothermal Absorption Correlation Spectroscopy

ACS Nano, 2009
Fluorescence correlation spectroscopy (FCS) is a popular technique, complementary to cell imaging for the investigation of dynamic processes in living cells. Based on fluorescence, this single molecule method suffers from artifacts originating from the poor fluorophore photophysics: photobleaching, blinking, and saturation.

Photothermal effect in Semiconductors

Physical Review, 1961
When a sample of semiconducting material is illuminated, pairs of excess carriers are generated which diffuse through the material according to the density gradients established. Each pair carries an energy approximately equal to the band gap of the material.
