Engineering of nanoemulsions for drug delivery

Sarker, Dipak·2005·Current Drug Delivery

Abstract

Nanoemulsions, usually spherical, are a group of dispersed particles used for pharmaceutical and biomedical aids and vehicles that show great promise for the future of cosmetics, diagnostics, drug therapies and biotechnologies. They exist in a wide variety of forms that are dictated by the particle components. Nanoemulsions are generally considered to be in the size range of less than and around 100 nm in diameter. The particles can exist as water-in-oil and oil-in-water forms, where the core of the particle is either water or oil, respectively. More complex variations also exist but these are often larger. The longer-term properties of the particle are dependent on the composition of the adsorbed material lying at the dispersed droplet interface with the dispersion medium. This has an impact on the partitioning and extraction of droplet contents. Thermodynamically stable particles are characterized by having a very low surface tension and this produces a very large surface area. Nanoemulsions can also include small meta-stable very small-scale emulsions; here the surface properties and chemistry can strongly influence behaviour. Processing, storage and formulation composition can also have an impact on the longevity of a pharmaceutical preparation. Some revolutionary new nanoemulsion droplets based on fluorinated compounds are finding a number of widespread biomedical roles and applications. Developments in nanoemulsion technology are likely to lead to a much greater use of this medium in future pharmaceuticals.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Nanoemulsions can be formulated into dosage forms such as liquids, creams, gels, foams and sprays and can be administered by oral, parenteral, ocular and nasal routes.

    “NEs can be formulated into different kinds of dosage forms like liquids, creams, gels, foams, sprays and so on, and can be administered by different routes including oral, parenteral and ocular, in addition to nasal [27].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
