Comparison of amino‐silanization of silica fiber‐optic biosensor probes using a PP/VS sequence with strategies involving wet‐chemical pretreatment or silanization shows a considerable improvement in reproducibility by the completely dry process. Practical applicability is demonstrated by an immunoassay with human immunoglobulin G as analyte. Thanks to the advantages of shorter processing time, avoidance of washing steps, and improved reproducibility, PP/VS is highly promising for industrial use.
