... and dielectric constant of the shell are controlled by the con- centration of AFP and gold colloid content. In order to find the effect of the dielectric shell on the fluorescence quenching from gold particle, ... the effect of gold colloids with different concentration on the fluorescence quenching of AFP. By calculating the quantum efficiency as a functio...

In particular, the appearance of a well-defined plateau region around a surface pressure of 17 mN/m for the concentration of 5 mg/ml is diagno stic of the formation of the liquid/solid-like ... copolymer film. Regarding the cause of this return of the dephasing we can do some hypothesis: (1) Gold segregation onto the polar domains because of the incre...
