Measuring the complex field scattered by single submicron particles / M.A.C. Potenza, T. Sanvito, A. Pullia. - In: AIP ADVANCES. - ISSN 2158-3226. - 5:11(2015 Nov), pp. 117222.117222-1-117222.117222-9. [10.1063/1.4935927]
Abstract:
We describe a method for simultaneous measurements of the real and imaginary parts of the field scattered by single nanoparticles illuminated by a laser beam, exploiting a self-reference interferometric scheme relying on the fundamentals of the Optical Theorem. Results obtained with calibrated spheres of different materials are compared to the expected values obtained through a simplified analytical model without any free parameters, and the method is applied to a highly polydisperse water suspension of Poly(D,L-lactide-co-glycolide) nanoparticles. Advantages with respect to existing methods and possible applications are discussed.
