Nanoparticles have different analytical requirements than conventional chemicals, for which chemical composition and concentration are sufficient metrics. Nanoparticles have other physical properties that must be measured for a complete description, such as size, shape, surface properties, crystallinity, and dispersion state. Additionally ...
Nanotechnology-on-a-chip is one more dimension of lab-on-a-chip technology. Magnetic nanoparticles, bound to a suitable antibody, are used to label specific molecules, structures or microorganisms. Silica nanoparticles, in particular, are inert from a photophysical perspective and can accumulate a large number of dye(s) within their shells. [42]
Magnetic nanoparticles can also be used in conjunction with imaging modalities like ultrasound to improve imaging. [9] The use of nanoparticles in ophthalmic drug delivery is also being explored in clinical research. Magnetic nanoparticles inserted into rats' corneas or administered in an eye drop solution showed high adhesion to the target ...
Attachments on nanoparticles make them more biocompatible. 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 ...
Nanoparticles can enhance the effects of traditional antibiotics which a bacterium may have become resistant to, and decrease the overall minimum inhibitory concentration (MIC) required for a drug. Silver nanoparticles improve the activity of amoxicillin , penicillin , and gentamicin in bacteria by altering membrane permeability and improving ...
Inorganic nanoparticles have been largely adopted to biological and medical applications ranging from imaging and diagnoses to drug delivery. [22] Inorganic nanoparticles are usually composed of inert metals such as gold and titanium that form nanospheres, however, iron oxide nanoparticles have also become an option.
Development of solid lipid nanoparticles is one of the emerging fields of lipid nanotechnology (for a review on lipid nanotechnology, see [17]) with several potential applications in drug delivery, clinical medicine and research, as well as in other disciplines. Due to their unique size-dependent properties, lipid nanoparticles can possibly ...
Engineered radioactive nanoparticles are being investigated for therapeutic use combining nuclear medicine with nanomedicine, especially for cancer. [3]: 125–130 Neutron capture therapy is one such potential application. [2] [4] In addition, nanoparticles can help to sequester the toxic daughter nuclides of alpha emitters when used in ...
