Abstract: HBsAg in human serum has been quantitatively determined by using laser photoacoustic enzyme linked immunosorbent assay method for which a novel photoacoustic cell with polyvinylidene fluoride film was designed.The detection limit of HBsAg and relative standard deviation are 1 pg/mLand 4.1%, respectively.

Key words: Laser photoacoustic spectrometry, Enzyme linked immunosorbent assay, Polyvinylidene fluoride, HbsAg
