- The purpose of this study was to develop a silica nanoparticle-based immunosensor with laser-induced fluorescence (LIF) as a detection system. The proposed device was applied to quantify the immunoreactive trypsin (IRT) in cystic fibrosis (CF) newborn screening. A new ultrasonic procedure was used to extract the IRT from blood spot samples collected on filter papers. After extraction, the IRT reacted immunologically with anti-IRT monoclonal antibodies immobilized on a microfluidic glass chip modified with 3-aminopropyl functionalized silica nanoparticles (APSN–APTES-modified glass chips). The bounded IRT was quantified by horseradish peroxidase (HRP)-conjugated anti-IRT antibody (anti-IRT–Ab) using 10-acetyl-3,7-dihydroxyphenoxazine (ADHP) as enzymatic mediator. The HRP catalyzed the oxidation of nonfluorescent ADHP to highly fluorescent resorufin, which was measured by LIF detector, using excitation lambda at 561 nm and emission at 585 nm. The detection limits (LODs) calculated for LIF detection and for a commercial enzyme-linked immunosorbent assay (ELISA) test kit were 0.87 and 4.2 ng ml−1, respectively. The within- and between-assay variation coefficients for the LIF detection procedure were below 6.5%. The blood spot samples collected on filter papers were analyzed with the proposed method, and the results were compared with those of the reference ELISA method, demonstrating a potential usefulness for the clinical assessment of IRT during the early neonatal period.
