A Label-Free Optical Biosensor Based on Ordered Porous Layer Interferometry for IgG Quantification in Milk
The study developed a label-free biosensor for IgG detection in milk, with a linear quantification range of 0.44 μg/mL to 5 mg/mL and high reproducibility. The biosensor is applicable across all stages of dairy production for IgG quality assessment.
