    en.wikipedia.org/wiki/Droplet-based_Microfluidics

    [citation needed] The emerging versatility of nanoparticles can be seen in the delivery of particle-loaded microdroplets being utilized in depot injections for drug delivery rather than the typical approach of injecting drugs intravenously. This is possible due to the low thickness of the shells which typically are in the range of 1 to 50 μm.

  3. Nanoparticle–biomolecule conjugate - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle–biomolecule...

    A nanoparticle–biomolecule conjugate is a nanoparticle with biomolecules attached to its surface. Nanoparticles are minuscule particles, typically measured in nanometers (nm), that are used in nanobiotechnology to explore the functions of biomolecules. Properties of the ultrafine particles are characterized by the components on their surfaces ...

  4. Characterization of nanoparticles - Wikipedia

    en.wikipedia.org/wiki/Characterization_of...

    Characterization of nanoparticles. Nanoparticles differ in their physical properties such as size, shape, and dispersion, which must be measured to fully describe them. The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.,.

  5. Surface plasmon resonance - Wikipedia

    en.wikipedia.org/wiki/Surface_plasmon_resonance

    Surface plasmon resonance (SPR) is a phenomenon that occurs where electrons in a thin metal sheet become excited by light that is directed to the sheet with a particular angle of incidence, and then travel parallel to the sheet. Assuming a constant light source wavelength and that the metal sheet is thin, the angle of incidence that triggers ...

    en.wikipedia.org/wiki/Nanotechnology_in_cosmetics

    Nanomaterials are materials with a size ranging from 1 to 100 nm in at least one dimension. At the nanoscale, material properties become different. These unique properties can be exploited for a variety of applications, including the use of nanoparticles in skincare and cosmetics products. Cosmeceuticals is one of the fastest growing industries ...

  7. Fick's laws of diffusion - Wikipedia

    en.wikipedia.org/wiki/Fick's_laws_of_diffusion

    Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...

  8. Nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle

    A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. [1][2] The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. [2]: 394 At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.
