Fig. 3. Phage vs antibody performance as a biorecognition element. Density of cells specifically captured by phage and antibody spots, covalently immobilized on gold solid surface. (A) The surface coverage was analyzed by ImageJ software. (B) Stereoscope pictures for representative spots of Salmonella cells specifically recognized by phage PVP-SE1 (top) and anti-Salmonella antibody (bottom). Statistical analysis for phage vs antibody results: *po0.05, ***po0.0001, two-way ANOVA.
