Since ,acid, dyes in ,solution, of near-neutral pH have the same sign of charge as the surfaces of most unmodified biomass, one can expect that dye adsorption will be highly dependent on either (a) various modifications of the substrate, including cationization, (b) bonding mechanisms other than attraction of opposite charges, and (c) the fact that most of the reported studies showed optimum biosorption of ,acid, …

The wafers were spun and IPA vapor dried as a function of the air exposure time. The hydrophilic wafers did not create any water marks with either spin or vapor dries. The air exposure time and dry method are much more sensitive with the hydrophobic surfaces in creating water marks.

It is hard to distinguish water that is originally from sample and water produced by Maillard reaction. That asks for ,determination, of two “kinds” of water: originally present in a sample and water produced in Maillard reaction. Karl Fischer titration is the most promising method for water ,determination, which relies on chemical reaction of water.
