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.
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.
The history of electrophoresis for molecular separation and chemical analysis began with the work of Arne Tiselius in 1931, while new separation processes and chemical speciation analysis techniques based on electrophoresis continue to be developed in the 21st century. [1]

Semaglutide is chemically similar to human GLP-1. [42] The first six amino acids of GLP-1 are missing. [42] Substitutions are made at GLP positions 8 and 34 (semaglutide positions 2 and 28), where alanine and lysine are replaced by 2-aminoisobutyric acid and arginine, respectively. [42]
Socrates ( / ˈsɒkrətiːz /; [1] Greek: Σωκράτης; c. 470 – 399 BC) was a Greek philosopher from Athens who is credited as the founder of Western philosophy and among the first moral philosophers of the ethical tradition of thought.
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]
The four tragedies of Prometheus attributed to Aeschylus, most of which are lost to the passages of time into antiquity, are Prometheus Bound ( Prometheus Desmotes ), Prometheus Unbound ( Lyomenos ), Prometheus the Fire Bringer ( Pyrphoros ), and Prometheus the Fire Kindler ( Pyrkaeus ).
