The realization that osmylation adds a 4-fold mass to the reacting base (Scheme 1, caption) fueled the speculation that any size-suitable nanopore could discriminate between osmylated and

The values R1 and R2 serve as quality control of the product because they can be calculated from the relationships R1 = 2.21 × dT/Ntotal and R2 = 2.01 × (dT+dC)/Ntotal, where Ntotal is the total number of nucleotides, dT/Ntotal is the fraction of dT, and (dT

Current state of the art instruments use micro-fabricated silicon and silicon-nitride cantilevers with an optical read-out [6] and image with high resolution down to the atomic scale. Furthermore, AFMs are often incorporated into quality control systems for

Thereby, the instrument can span over three orders of magnitude in scan range, which makes it a helpful tool for micro- and nanomechanical analysis. One example of such an analysis is given in Figure 4a. For quality control of fabrication
