Polyethylene Glycol 20k. Does It Fluoresce?

Figure 4 from « Polyethylene Glycol 20k. Does It Fluoresce?» by Bethany F. Laatsch, et al: AFM images of the PEG 20 k on the HOPG substrate. (a) Height-retraced and (b) amplitude-retraced images of PEG 20k on the HOPG substrate. Each AFM image size is 5 μm × 5 μm. The key in each image indicates a length of 1 μm. Scans were conducted in a 5 μm area using the NANOSENSORS uniqprobe qp-BioAC afm probe and a force constant of 0.15–0.55 N/m.

Polyethylene glycol (PEG) is a polyether compound commonly used in biological research and medicine because it is biologically inert. * This simple polymer exists in… Read More »Polyethylene Glycol 20k. Does It Fluoresce?
