The paper identifies the multi-matrix challenge as the primary barrier to commercial deployment. It also highlights the limitations of current biosensor surfaces, which depend on macroscopic physical homogenization, sonication, and liquid dilution. The study notes that true, undiluted direct analysis remains unrealized.
