Relationship of fluorescence and membrane weight. Electrospun membrane material (PVC-COOH 10%w/w CB) of differing weights functionalized with avidin was interrogated with biotin-QD complexes. The fluorescence intensity (mean ± standard error, n = 18) has a 2nd order polynomial relationship to the membrane weight, y = -4.757x2 + 88.878x - 75.945 (R2= 0.9973).
