1. Illustration of electrophoresis. 2. Illustration of electrophoresis retardation. In chemistry, electrophoresis is the motion of charged dispersed particles or dissolved charged molecules relative to a fluid under the influence of a spatially uniform electric field. As a rule, these are zwitterions.
Mechanisms of action. While increased skin permeability is seen through sonophoresis, the precise mechanisms to describe sonophoresis are yet to be fully discovered. However, there are several important mechanisms that have been identified that contribute to the phenomenon of sonophoresis.
Iontophoresis is a process of transdermal drug delivery by use of a voltage gradient on the skin. [1] [2] Molecules are transported across the stratum corneum by electrophoresis and electroosmosis and the electric field can also increase the permeability of the skin.
An Aloka SSD 3500 ultrasound machine. Phonophoresis, also known as sonophoresis, is the method of using ultrasound waves to increase skin permeability in order to improve the effectiveness of transdermal drug delivery. This method intersects drug delivery and ultrasound therapy.
Moving-boundary electrophoresis was developed by Arne Tiselius in 1930. [3] Tiselius was awarded the 1948 Nobel Prize in chemistry for his work on the separation of colloids through electrophoresis, the motion of charged particles through a stationary liquid under the influence of an electric field.

Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their activities.
Phosphorus is an essential mineral for humans listed in the Dietary Reference Intake (DRI). Food-grade phosphoric acid (additive E338 [104]) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. The phosphoric acid also serves as a preservative. [105]
Leprosy. Leprosy, also known as Hansen's disease ( HD ), is a long-term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis. [4] [7] Infection can lead to damage of the nerves, respiratory tract, skin, and eyes. [4] This nerve damage may result in a lack of ability to feel pain, which can lead to the loss of parts of a ...
Hermaphrodite. A hermaphrodite ( / hərˈmæfrəˌdaɪt /) is a sexually reproducing organism that produces both male and female gametes. [1] Animal species in which individuals are either male or female are gonochoric, which is the opposite of hermaphroditic. [2] The individuals of many taxonomic groups of animals, primarily invertebrates, are ...
