PMID-25128375 Chronic tissue response to carboxymethyl cellulose based dissolvable insertion needle for ultra-small neural probes.

  • CMC = carboxymethyl cellulose, commonly used as a food additive, in toothpaste, etc.
  • To address CMC dissolution, we developed a sophisticated targeting, high speed insertion (∼80 mm/s), and release system to implant shuttles.
  • Cross section of the probes are large, 300 x 125um and 100 x 125um.
  • Beautiful histology: the wound does gradually close up as the CMC dissolves, but no e-phys.
