“…From the spectra it is also worth noting that a decrease in the intensity of the band located at 2840 cm -1 , characteristic from Si-O-CH 3 (Lee & Kim, 2012), was observed and a band characteristic from Si-O-C (Lee & Kim, 2012), located at approximately 1000 cm -1 , was discerned after reaction of APTS with cellulose. Additionally, the broad band between 3000 and 3700 cm -1 detected for the coated material, can be assigned to NH 2 stretching and to Si-OH and the peaks at 1635 cm -1 and 1568 cm -1 to NH 2 stretching vibration and to the bending band of protonated amines, respectively (Xia et al, 2006). These spectral changes confirmed that indeed methoxy groups from the silane were hydrolysed and the silane was bonded to cellulose.…”

“…This is usually done as a preliminary step which ends with the biomolecule immobilisation. Xia and coworkers published a study where porous silicon surfaces were bio-functionalised by a simple three-step method (Xia et al 2006). A scheme of the functionalising procedure is shown in Fig.…”
