Polyaniline films with nanostructure used as neural probe coating surfaces

Poly(tetrafluoroethylene) composite membranes coated with urchin-like polyaniline hiberarchy: Preparation and properties

“…The superhydrophilicity results are similar to the report of hydrophilic PANI nanowires and sub-micro/nanostructured dendrites immobilized on the PP-g-PAA membranes surface [35]. In our case, the CA decrease with more deposited conductive PANI on the PTFE/Nafion membranes, which is due to the decrease in the surface heterogeneity of the PTFE/Nafion/PANI membranes and thus reduction in the interfacial free energy between the PTFE/PANI composite membranes and water [36]. When [ANI]/[p-TSA] ratio is changed to 1:3, the PANI with novel urchin-like morphology deposited on the PTFE membrane can provide a micro-scale rough surface.…”

Protein adsorption under electrical stimulation of neural probe coated with polyaniline

“…PANI films were synthesized as our paper reported previously [25] with a little modification. In a typical synthesis, aniline monomer (8 mmol, stored under argon at 4 • C) was dissolved in 50 mL of methylene chloride, and (NH 4 ) 2 S 2 O 8 (4 mmol) was dissolved in 50 mL of 1 M dopant acid solution including HClO 4 and citric acids, respectively.…”

Carbon nanotubes in neural interfacing applications

“…Polyethyleneimine (PEI) and poly-L-ornithine (PLO) are commonly used polymers that promote neural cell attachment. Both polyethylenedioxythiophene (PEDOT) and polypyrrole (PPy) have also been used as neural growth substrates, and are of particular interest for coatings on neural interface devices due to their high electrical conductivity [27][28][29][30]. However, many synthetic and conductive polymers are fabricated using complex or toxic polymerization schemes that are not well suited to cell contacting applications, and these materials are still limited in their effectiveness when compared to natural factors [31].…”
