  2. Sonophoresis - Wikipedia

    en.wikipedia.org/wiki/Sonophoresis

    Sonophoresis also known as phonophoresis, is a method that utilizes ultrasound to enhance the delivery of topical medications through the stratum corneum, to the epidermis and dermis. Sonophoresis allows for the enhancement of the permeability of the skin along with other modalities, such as iontophoresis , to deliver drugs with lesser side ...

  3. Phonophoresis - Wikipedia

    en.wikipedia.org/wiki/Phonophoresis

    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 .

  4. Iontophoresis - Wikipedia

    en.wikipedia.org/wiki/Iontophoresis

    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. [3] [4] These phenomena, directly and indirectly, constitute active transport ...

  5. Nanocapsule - Wikipedia

    en.wikipedia.org/wiki/Nanocapsule

    The ultrasound can either be low-frequency, or LFUS, (between ~20 and ~100 kHz) or high-frequency, HFUS, (>1 MHz). Transdermal delivery (sonophoresis) is enhanced through LFUS, which then further allows the drug to be released. Since the wave of HFUS is higher, success of drug delivery has been demonstrated through the form of bubbles.

  6. Bessel function - Wikipedia

    en.wikipedia.org/wiki/Bessel_function

    Bessel functions describe the radial part of vibrations of a circular membrane. Bessel functions, first defined by the mathematician Daniel Bernoulli and then generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel's differential equation

  7. Schrödinger equation - Wikipedia

    en.wikipedia.org/wiki/Schrödinger_equation

    Schrödinger's equation inscribed on the gravestone of Annemarie and Erwin Schrödinger. ( Newton's dot notation for the time derivative is used.) The Schrödinger equation is a linear partial differential equation that governs the wave function of a quantum-mechanical system.

  8. Dopamine - Wikipedia

    en.wikipedia.org/wiki/Dopamine

    Dopamine ( DA, a contraction of 3,4- d ihydr o xy p henethyl amine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80% of the catecholamine content in the brain.

  9. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    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.

  10. Poisson distribution - Wikipedia

    en.wikipedia.org/wiki/Poisson_distribution

    In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event. [1]
