Purified silicon lattice

To answer all these questions, in vitro recrystallization experiments were conducted on a Si wafer. To this end, recrystallization experiments were carried out by first monomerizing 0.5 mg of the purified S-layer with 5 M GuHCl. After monomerization, one-fifth of the protein solution was dialyzed against 10 mM Tris/HCl buffer pH 3 at 4 °C in the presence of APTES functionalized Si substrate. After 2 h, the substrates were taken out, washed in distilled water and dried on air. AFM was used for imaging the topography of the recrystallized S-layer lattices on the silicon wafer. Figure 3.10 shows the structures obtained.
