Nov 15, 2016 . Furthermore, the gold nanoparticles alone can generate singlet oxygen [29]. So combination of GNPs-mediated photothermal therapy (PTT) and photosensitizers-mediated photodynamic therapy (PDT) was reported to achieve synergistic PTT and PDT effects on destroying cancer cells by many groups [7,.

Gold Nanoparticle Mediated Laser Transfection for Efficient siRNA .

Mar 11, 2013 . Laser based transfection methods have proven to be an efficient and gentle alternative to established molecule delivery methods like lipofection or electroporation. Among the laser based methods, gold nanoparticle mediated laser transfection bears the major advantage of high throughput and easy.

the chemistry and biology of gold nanoparticle-mediated .

Under laser radiation, cells labeled with gold nanoparticles (AuNPs) are believed to suffer thermal damage due to the transfer of the absorbed light from the AuNPs to the cells. This process, which involves complex mechanisms such as the rapid electron–phonon decay in the AuNPs, followed by phonon–phonon relaxation,.

Delivery of proteins to mammalian cells via gold nanoparticle .

Compared to conventional protein transfection techniques such as microinjection, the methodical approach presented here enables high-throughput transfection of about 10 000 cells per second. Moreover, a well-defined point in time of delivery is guaranteed by gold nanoparticle mediated laser transfection, allowing the.

May 20, 2016 . Interaction of gold nanoparticles (AuNPs) in the vicinity of cells' membrane with a pulsed laser (λ = 532 nm, τ = 1 ns) leads to perforation of the cell membrane, thereby allowing extracellular molecules to diffuse into the cell. The objective of this study was to develop an experimental setting to deliver.

OSA | Gold Nanoparticle-Mediated Laser Stimulation Causes a .

Gold nanoparticle mediated laser stimulation of neuronal cells allows for cell activation on a single-cell level. It could therefore be considered an alternative to classical electric neurostimulation. The physiological impact of this new approach has not been intensively studied so far. Here, we investigate the targeted cell's.

The role of mitochondrial function in gold nanoparticle mediated .

Abstract. Gold nanoparticles (GNPs), have been demonstrated as effective preclinical radiosensitising agents in a range of cell models and radiation sources. These studies have also highlighted difficulty in predicted cellular radiobiological responses mediated by GNPs, based on physical assumptions alone, and therefore.

Understanding cell death response to gold nanoparticle-mediated .

Gold nanoparticles, a class of plasmonic nanoparticle, have increasingly been explored as an imaging and therapeutic agent to treat cancer due to their characteristic surface plasmon resonance phenomenon and penchant for tumor accumulation.

Abstract 851: Gold nanoparticle-mediated infrared hyperthermia .

Oct 1, 2014 . Abstract. Gold nanoparticles (AuNPs) absorb light and can be used to heat and ablate tumors. The “tissue window” at ∼800 nm (near infrared, NIR) is optimal for best tissue penetration (∼2cm). Previously large, 50-150nm gold nanoshells and nanorods that absorb well in the NIR have been used. Here we.
