Abstract: A nanoparticle screening chip and a method using said chip allowing for determining physical properties of nanoparticles, wherein the screening chip comprises a substrate having a working surface divided into a plurality of areas, wherein (1) each of these areas presents different surface properties defined by surface energy component (d,b,a), the total free energy γTOT of the surface of each area being defined as follows: γTOT=γLW+2(γ+γ−)0.5, wherein the components are: γLW=dispersive component=d, γ+=electron acceptor component=b, γ−=electron donor component=a; and (2) each of these areas comprises a plurality of subareas, each subarea comprising an array of sub-micrometric holes or elongated grooves with a different aperture size (S1, S2, S3, . . . ).
