What is plasmonic photothermal effect?
Plasmonic photothermal therapy (PPTT) utilizes light in the near-infrared (NIR) region to induce highly localized heating in gold nanoparticles, acting as exogenous chromophores, while minimizing heat generation in nearby tissues.
What is plasmonic photothermal?
Plasmonic photothermal therapy (PPTT), a type of treatment involving the intravenous or intratumoral injection to introduce gold nanoparticles to cancerous cells and the subsequent exposure to heat-generating near-infrared (NIR) light, is a potentially favorable alternative to traditional treatments of localized tumors …
What is lspr nanoparticles?
A localized surface plasmon (LSP) is the result of the confinement of a surface plasmon in a nanoparticle of size comparable to or smaller than the wavelength of light used to excite the plasmon.
What is photothermal reaction?
Photothermal effect is a phenomenon associated with electromagnetic radiation. It is produced by the photoexcitation of material, resulting in the production of thermal energy (heat). It is sometimes used during treatment of blood vessel lesions, laser resurfacing, laser hair removal and laser surgery.
What is LSPR effect?
Localized surface-plasmon resonance (LSPR) refers to the collective oscillation of electrons at the interface of metallic structures, which could be produced through the electron-magnetic interaction of the metal with incident light of a specific wavelength (Haes and Van Duyne, 2002; McFarland and Van Duyne, 2003; …
How does the photothermal effect work?
Photothermal therapy is a minimally invasive, local treatment modality that mainly relies on an optical absorbing agent, also known as photosensitizer, which can absorb energy and convert it into heat upon stimulating by an electromagnetic radiation such as radiofrequency, microwaves, near infrared irradiation, or …
What photothermal means?
Definition of photothermal : of or relating to both light and heat.
What causes LSPR?
In LSPR, the electric field component of the incident light interacts with the electrons of each metallic particle, causing the collective electron density to oscillate at a frequency that is resonant with the incoming light.
What is meant by photothermal?
: of or relating to both light and heat.
What is a photothermal material?
Photothermal materials can efficiently absorb and convert light energy into heat. The produced heat could be served in various applications, including phototherapy, photoimaging, and clean water production.
