21 Jul 2014 Scientists explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs.
2014-03-22 · Surface plasmon resonance-induced photoactivation of gold nanoparticles as bactericidal agents against methicillin-resistant Staphylococcus aureus. Mocan L (1), Ilie I (2), Matea C (1), Tabaran F (1), Kalman E (1), Iancu C (1), Mocan T (3). Gold nanoparticles (Au NPs) with an average size of about 10 nm were deposited in situ into the TiO 2 bi-layer structure. The extended photoelectrochemical (PEC) water splitting activity in visible light was ascribed to the energetic hot electrons and holes that were generated in the Au NPs through the excitation and decay of surface plasmons.

Instead, it uses gold nanoparticles to generate what is known as localized surface plasmon resonance (LSPR). Overview of Localized. Surface Plasmon. 7 Sep 2020 Gold nanoparticles possess unique optoelectronic properties due to the presence of a surface plasmon resonance band. These characteristics 21 Jul 2014 Scientists explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs. 29 Mar 2021 In these plasmon-coupled gold particles, researchers discovered optical properties that vary with the distance of the clusters to each other.
In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the subject of intense research efforts. Plasmon physics is intriguing and its precise modelling proved to be challenging. In fact, plasmons are highly responsive to a multitude of factors, either intrinsic to the Au NPs or from the environment, and recently the need emerged for the correction of standard The slight blue shift in plasmon resonance position observed at sample calcination from 200 to 500 °C may be attributed to changes in the dielectric screening of the matrix, the fraction distribution of reduced gold, the elimination of NH 4 + or OH-, or size of the nanoparticles (due to thermal agglomeration of reduced gold).
Gold nanoparticles resonance is localized in visible spectrum , Christina Graf and co-workers, affirmed that the Surface Plasmon Resonance (SPR) of gold nanospheres of 5 nm of radius embed in water are localized at 520 nm whereas SPR of silver nanospheres is localized towards 410 nm [11, 12].

For small (~30nm) monodisperse gold nanoparticles, the surface plasmon resonance phenomenon causes an absorption of light in the blue-green portion of the spectrum (~450 nm) while red light (~700 nm) is reflected, yielding a rich red color. We show that the spectral response of this system results from the interplay between the localized plasmon resonance of the nanoparticle and the surface plasmon polaritons of the gold film, as previously predicted by theoretical studies. As a result of aggregation, the localized surface plasmon resonance band of gold nanoparticles decreased to around 525 nm and a new red-shifted band at 640 nm appeared which increases gradually as the function of Cefixime concentration.
