Fig. 5: Electroadhesion of QDM gel to bovine tissue.
From: Reversible electroadhesion of hydrogels to animal tissues for suture-less repair of cuts or tears
a A strip of tissue (T−), specifically bovine aorta, and a strip of cationic QDM gel (G+) are contacted in a E+G+T−E− configuration, with the gel touching the positive and the tissue the negative electrode. 10 V of DC is then applied for 20 s. b This causes the gel to become strongly adhered to the tissue. c When the gel-tissue pair is placed in the field with reversed polarity (E+T−G+E−), then within 10 s, the adhesion is lost and the gel can be detached from the tissue. The above photos are stills from Supplementary Movie 3.
