Review of Long-Wavelength Optical and NIR Imaging Materials: Contrast Agents, Fluorophores, and Multifunctional Nano Carriers
TL;DR: The wavelength range of 650-1450 nm falls in the region of the spectrum with the lowest absorption in tissue and therefore enables the deepest tissue penetration and is the wavelength range focused on with this review.

Kinetic study of the formation of polypyrrole nanoparticles in water-soluble polymer/metal cation systems: a light-scattering analysis.
TL;DR: Major physical parameters affecting the formation of polymer nanoparticles are investigated, including hydrodynamic radius, radius of gyration, shape factor, and viscosity, and by judicious control of these parameters, PPy nanoparticles with narrow size distribution can be readily fabricated in large quantities.

Measurement of sheet resistivities with the four-point probe
TL;DR: In this paper, correction factors are evaluated for the measurement of sheet resistirities on two-dimensional rectangular and circular samples with the four-point probe, and the factors are also useful in obtaining body resistivities on thin samples.

Chemical oxidative polymerization as a synthetic route to electrically conducting polypyrroles
TL;DR: In this paper, various transition metal compounds, specifically Fe (III and Cu (II) complexes, are shown to function both as polymerization initiators and as dopants in converting pyrrole and substituted pyrroles into electrically conducting polymers.
