▎ 摘　　要

NOVELTY - The assembly (100) has a thin film (102) placed on a support base (101). The thin film includes a thickness of less than 10 nanometer. A spherical nanoparticle (106) is provided between the thin film and support base, and functionally constitutes a spacer between the thin film and base. The spherical nanoparticles account for 50-90% in a portion of a space (104) between the thin film and the base. A cell includes a circumference formed by the thin film locally being in contact with the base. USE - Thin-film-based assembly for analyzing a sample such as proteins, vesicles and viruses, in a cell (all claimed) i.e. graphene liquid cell. ADVANTAGE - The spherical nanoparticles provide a form of control over the space that is formed between the support base and the thin film. The thin film provides a relatively high degree of transparency, thus allowing a relatively precise analysis of what is inside the space and what happens inside the space. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for forming a thin-film-based assembly. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of a graphene liquid cell comprising spherical nanoparticles that functionally constitute spacers. 100Thin-film-based assembly 101Support base 102Thin film 104Space 106Spherical nanoparticle
