XPS is known as a surface-sensitive method that allows us to obtain quantitative information about the chemical composition of organic materials. Here we present technological challenges in XPS analysis of AAs and cells (geobacter, Algae). The first part focuses on an understanding of the actual mechanisms of AAs interaction with H-/O-terminated NCD and DLC films using XPS. The detailed processing of XPS data revealed the dependence of AAs adhesion on the surface termination of carbon-based materials. The second part focuses on the investigation of intact interfaces of centrifuged wet pastes of geobacter and Algae followed by XPS at liquid nitrogen temperatures. The detailed XPS analysis of C 1s, O 1s, N 1s and S 2p peaks was discussed. This work was supported by project ESIF and MEYS (Project “FZU- researchers, technical and administrative staff mobility” – CZ.02.2.69/0.0/0.0/18_053/0016627), by project VEGA 1/0554/20 and by the Czech Science Foundation (project No. 20-00925Y).
