^afor simplification, the film of PHEMA and acrylamide copolymer was called PHEMA.

^bCon.: concentration in mg/g of sensor/matrix;

^cλ_ex in nm: only the Soret band was listed in the table, the Q bands at 508 and 540 nm were not listed.

^dbroad peak.

^enumbers in the parentheses are the correlation coefficients (R²) of the fitting.
