Microchimica Acta (MCA) has established itself as a premier forum for research results in modern (bio)analytical sciences based on the use of micro/nano-structured materials. Coverage includes fundamental studies on, practical applications of, and new approaches towards micro-/nanomaterials such as micro- and nanoparticles, imprints, micro/nanodroplets, or micro/nanostructured devices for use in (bio)analytical applications including sensing and preconcentration. Invited reviews provide a critical assessment of research progress in these fields
