  2. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    If the apparent size of the particles increases due to them clumping together via aggregation, it will result in slower Brownian motion. This technique can confirm that aggregation has occurred if the apparent particle size is determined to be beyond the typical size range for colloidal particles. [21]

  3. Oncotic pressure - Wikipedia

    en.wikipedia.org/wiki/Oncotic_pressure

    Oncotic pressure values are approximately 290 mOsm per kg of water, which slightly differs from the osmotic pressure of the blood that has values approximating 300 mOsm /L. [citation needed] These colloidal solutions are typically used to remedy low colloid concentration, such as in hypoalbuminemia, but is also suspected to assist in injuries ...

  4. Particle size - Wikipedia

    en.wikipedia.org/wiki/Particle_size

    In materials science and colloidal chemistry, the term colloidal particle refers to a small amount of matter having a size typical for colloids and with a clear phase boundary. The dispersed-phase particles have a diameter between approximately 1 and 1000 nanometers .

  5. Dispersion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(chemistry)

    However, the complexity is usually reduced by comparing the measured size distribution of "primary" particles to that of the agglomerates or aggregates. [7] When discussing suspensions of solid particles in liquid media, the zeta potential is most often used to quantify the degree of dispersion, with suspensions possessing a high absolute value ...

  6. Sol (colloid) - Wikipedia

    en.wikipedia.org/wiki/Sol_(colloid)

    A sol is a colloidal suspension made out of tiny solid particles [1] in a continuous liquid medium. Sols are stable, so that they do not settle down when left undisturbed, and exhibit the Tyndall effect, which is the scattering of light by the particles in the colloid. The size of the particles can vary from 1 nm - 100 nm.

  7. Gold nanoparticles in chemotherapy - Wikipedia

    en.wikipedia.org/wiki/Gold_nanoparticles_in...

    Gold nanoparticles that act as drug delivery systems in conjugation with chemotherapeutic drugs typically range in size from 10 to 100 nm. [ 2 ] Surface area plays a very important role in drug delivery and per mg of gold, as diameters decrease, the surface areas needed to transport drugs increase to the point where a single 1mL volume of 1.8 ...

  8. Zeta potential - Wikipedia

    en.wikipedia.org/wiki/Zeta_potential

    The zeta potential is an important and readily measurable indicator of the stability of colloidal dispersions. The magnitude of the zeta potential indicates the degree of electrostatic repulsion between adjacent, similarly charged particles in a dispersion. For molecules and particles that are small enough, a high zeta potential will confer ...

  9. Nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle

    A colloid is a mixture which has particles of one phase dispersed or suspended within an other phase. The term applies only if the particles are larger than atomic dimensions but small enough to exhibit Brownian motion, with the critical size range (or particle diameter) typically ranging from nanometers (10 −9 m) to micrometers (10 −6 m).
