Lycopene (LP), an important functional compound in tomatoes, and gold nanoparticles (AN), have received considerable attention as potential candidates for cancer therapy. However, the extreme instability and poor bioavailability of LP limits its in vivo application. This study intends to develop a nanoemulsion system incorporating both LP and AN, and to study the possible synergistic effects on...

Catalysis using supported gold nanoparticles has attracted significant research interest due to their unique properties and potential that is directly related particle size. An efficient one-pot, three-component procedure developed for the preparation of pyrimido[4,5- b][1,6]naphthyridin-4( 1H)-one derivatives (4a–h) by cyclocondensation 6-amino-2-thioxo-2,3-dihydropyrimidin-4( (1), aromatic al...

A homogeneous-heterogeneous immunoassay based on the use of antibody modified gold nanoparticles, 5 and 50 nm in diameter, is developed with without signal amplification. The assays involve capture target analytes homogeneous phase subsequent detection immunoreaction product, following a heterogeneous scheme performed regular DVD. analytical approach was evaluated developing multiplexed competi...
