From: Quantification of the CBD-FITC conjugates surface coating on cellulose fibres
Images obtained by fluorescence microscopy of Whatman CF11, amorphous and Sigmacell 20 fibres. The images were obtained before – 1st and 3rd column – and after – 2nd and 4th column – the image analysis of fibres treated with a CBD-FITC concentration of 400 μg/mL. The black areas on the treated images correspond to the fluorescence emission, which is higher than the one used in the calibration. Fluorescence images acquired for 100 ms (CF11) and 80 ms (Amorphous and Sigmacell).
