Enhanced photothermal displacement spectroscopy for thin-film characterization using a Fabry-Perot resonator [PDF]

open access: yes, 2003
We have developed a technique for photothermal displacement spectroscopy that is potentially orders of magnitude more sensitive than conventional methods.

Numerical Study of Photoacoustic Pressure for Cancer Therapy

open access: yesApplied Sciences, 2016
A commonly used therapy for cancer is based on the necrosis of cells induced by heating through the illumination of nanoparticles embedded in cells. Recently, the photoacoustic pressure shock induced by the illumination pulse was proved and this points ...

Gold Nanoparticles as a Photothermal Agent in Cancer Therapy: The Thermal Ablation Characteristic Length

open access: yesMolecules, 2018
In cancer therapy, the thermal ablation of diseased cells by embedded nanoparticles is one of the known therapies. It is based on the absorption of the energy of the illuminating laser by nanoparticles.

Improving the optomechanical entanglement and cooling by photothermal force

open access: yes, 2012
Cooling and Entanglement in optomechanical systems coupled through radiation pressure and photothermal force is studied. To develop the photothermal model, we derive an expression for deformation constant of the force.

Laser Induced Aggregation of Light Absorbing Particles by Marangoni Convection

open access: yesApplied Sciences, 2020
Laser induced Marangoni convection can be used to accumulate micro-particles. In this paper, a method is developed to control and accumulate the light absorbing particles dispersed in a thin solution layer. The particles are irradiated by a focused laser

Quantum limit of photothermal cooling

open access: yes, 2010
We study the problem of cooling a mechanical oscillator using the photothermal (bolometric) force. Contrary to previous attempts to model this system, we take into account the noise effects due to the granular nature of photon absorption.

Melanocortin 1 receptor targeted imaging of melanoma with gold nanocages and positron emission tomography [PDF]

open access: yes, 2018
Purpose: Melanoma is a lethal skin cancer with unmet clinical needs for targeted imaging and therapy. Nanoscale materials conjugated with targeting components have shown great potential to improve tumor delivery efficiency while minimizing undesirable ...

Coexisting attractors and chaotic canard explosions in a slow-fast optomechanical system

open access: yes, 2013
The multiple time scale dynamics induced by radiation pressure and photothermal effects in a high-finesse optomechanical resonator is experimentally studied.

Remote photothermal actuation for calibration of in-phase and quadrature readout in a mechanically amplified Fabry-Pérot accelerometer [PDF]

open access: yes, 2014
A mechanically amplified Fabry-Pérot optical accelerometer is reported in which photothermal actuation is used to calibrate the in-phase and quadrature (I&Q) readout.
