cataphoresisn.

1889 N.Y. Med. Jrnl. 27 Apr. 449/1 (heading) Electric cataphoresis as a therapeutic measure.

1890 J. S. Billings Med. Dict. Kataphoresis.

1895 Buck's Handbk. Med. Sci. Suppl. 267/1 The use of iodine by cataphoresis has been attempted in cases of goître.

1908 Times 9 Oct. 10/1 The possibility of using cataphoresis as a means of conveying foods and drugs to the system.

1944 Electronic Engin. 16 341 When a solid particle becomes suspended in a liquid medium of higher dielectric constant it becomes, in general, negatively charged relative to the dispersion medium and will therefore be attracted to the anode of an electrode system placed in the solution. This phenomenon is known as cataphoresis.

1944 S. Field Princ. Electrodeposition (new ed.) xx. 279 Since colloidal suspensions are electrically charged they migrate to one electrode or the other under the influence of an applied P.D. This motion is known as cataphoresis or electrophoresis.

1949 Electronic Engin. 21 405 One application of these aspect ratio resistors is to coat a sheet of insulating material by a capillary process, by spraying or by cataphoresis with a uniform resistance film of constant value of ohms per square.

1889 N.Y. Med. Jrnl. 27 Apr. 449/1 The cataphoretic action of electricity has often been made use of experimentally to introduce drugs into the system through the skin.

1944 Electronic Engin. 16 341 It is logical to regard electrolytic conduction as the limiting case of cataphoretic conduction.

1954 Electronic Engin. 26 404 It has been found that the cataphoretic coating process has some advantages.
