UV autofluorescence of both neutral (a) and alkaline (b) RH and RS samples (untreated UT and pretreated PT). The numbers 1 and 2 represent RH samples and RS samples respectively. In a (neutral), only blue autofluorescence occurs, symptomatic of lignin and pCA. In b (alkali), the RH autofluoresces blue, whilst the RS autofluorescencence is turquoise/green symptomatic of tFA and associated moieties. Scale bar: 100 µm
