Absorption of light by spherical nanoparticle

  1. May 19, 2013 #1
    Hello

    Can anyone tell me how the absorption of a polystyrene nanoparticles scales as a function of its diameter.

    The particle is spherical and it is placed in vacuum.

    A reference to a paper I can read would be nice.

    At this point I only want to know how the absorption scales not how much the particles absorbs.

    Thanks.

    The specific absorption would be a constant for the material (proportion of light absorbed per unit area).
    What is the context?

    I have this experiment where I can measure the absorption of light by a single nanoparticle. I would then like to calculate the detection limited based on the noise of the measurement and the signal induced by the particle I can detect.
