Web5 apr. 2024 · According to the QCM-D data, the adsorbed PS-b-PAA primer remained stable up to the highest salt concentration of 1.0 M (Figure S26 and Table S3). Next, highly reproducible hybrid coatings were generated on top of PS-coated sensors ( Figure 7 a and Figure S27 ) within the QCM-D, which were subsequently exposed to buffer solutions of … WebFig. 3 shows that T cloud is linearly proportional to the ionic strength of added alkali-halide salt I ion. Slopes of these curves are determined by the salt type (39, 40). An increase of T cloud can be interpreted as an increased attraction between protein molecules at increased alkali-halide salt ionic strength I ion.
