Photochemical Synthesis of the Bioconjugate Folic Acid-Gold Nanoparticles

Nanomaterials and Nanotechnology Photochemical Synthesis of the Bioconjugate Folic Acid-Gold Nanoparticles

In this paper we present a rapid and simple onepot method to obtain gold nanoparticles functionalized with folic acid using a photochemistry method. The bioconjugate folic acid-gold nanoparticle was generated in one step using a photo-reduction method, mixing hydrogen tetrachloroaurate with folic acid in different ratios and varying the illumination time of a mercury lamp (λ= 255 nm). Scanning ...

Liposomes as nanoreactors for the photochemical synthesis of gold nanoparticles.

A simple and novel method for the photochemical synthesis of AuNPs in liposomes is described. Gold salt is co-encapsulated with the photoinitiator Irgacure-2959 in POPC liposomes prepared via traditional thin-film hydration technique. UVA irradiation for 15 min results in encapsulated AuNPs of 2.8±1.6 nm in diameter that are primarily dispersed in the aqueous interior of the liposomes.

Photochemical synthesis of gold nanorods.

Gold nanorods have been synthesized by photochemically reducing gold ions within a micellar solution. The aspect ratio of the rods can be controlled with the addition of silver ions. This process reported here is highly promising for producing uniform nanorods, and more importantly it will be useful in resolving the growth mechanism of anisotropic metal nanoparticles due to its simplicity and t...

Folic acid-modified diatrizoic acid-linked dendrimer-entrapped gold nanoparticles as nanoprobes for targeted CT imaging of human cervical cancer

Electron transfer from the benzophenone triplet excited state directs the photochemical synthesis of gold nanoparticles.

The rarely recognized electron donating ability of the benzophenone triplet excited state provides an unusual route for the photochemical synthesis of gold nanoparticles.
