Abstract: A PTSM-coated expandable microsphere comprises a polymer shell enclosing an interior volume containing at least one blowing agent. The polymer shell has an outer surface with photothermal susceptor material disposed on at least a portion thereof. If heated to at least one temperature greater than 25° C., each of the expandable microspheres expands, but does not rupture, the polymer shell by a sufficient amount to at least double the interior volume. A markable comprises a substrate and a viewable layer secured thereto. The viewable layer comprises a binder material retaining the PTSM-coated expandable microspheres. A method of marking a markable article comprises imagewise exposing the PTSM-coated expandable microspheres of the markable article to at least sufficient electromagnetic radiation to cause the PTSM-coated expandable microspheres to expand thereby creating a predetermined image. A marked article preparable according to the method is also disclosed.

Abstract: A method and system for tissue impedance measurement are disclosed. In examples, the system comprises electrical contacts configured to be coupled to a first tissue and a first device configured to apply a first electrical signal to the first tissue via the electrical contacts. The system further comprises a second device configured to determine a first impedance phase angle of epithelial tissue of the first tissue site based on the first applied electrical signal, determine a baseline impedance phase angle of epithelial tissue corresponding to a second tissue, determine information indicative of epithelial tissue characteristics based on a ratio of the first impedance phase angle and the baseline impedance phase angle, and output information indicative of the epithelial tissue characteristics.
