Figure 2From: Application of a biotin functionalized QD assay for determining available binding sites on electrospun nanofiber membraneEmission spectra of PVC-COOH membrane. Fluorescence emission spectra of PVC-COOH electrospun nanofiber membrane with and without 10% w/w carbon black at 400 nm excitation. Fluorescence was measured on an Aminco Bowman II front face spectrophotometer.Back to article page
