Inorganic and organic nanoparticles employed in creams, implants, drug carriers or as contrast agents need biocompatibility studies to test their potential cytotoxicity
Gold nanoprisms could be appropriate candidates for in vitro cellular thermoablation due to their efficient internalization and heating capacity
Advances in nanophotonics have shown the potential of colloidal metal particles with sharp tips, such as nanostars, to focalize the plasmonic electromagnetic fields.
Silver ions have been shown to be an effective bactericide. These particles, as an antibacterial component, have been used in the formulation of dental resin composites and ion exchange fibers and in coatings of medical devices.
MagneticHyperthermia: magneticnanoparticles heated by an alternating magnetic field could be used to treat cancers, either alone or in combination with radiotherapy or chemotherapy.
Heatsens biosensor technologycan be used to detect very quickly the presence, at ultralow concentrations, of animportant tumoral marker like CEA.
A key challenge for many applications is to control the organization of antibodies on surfaces whilst retaining their biological activity.
The application of AuNPsto the commercially available ELISA test can be useful to improve important immunoanalysis procedures where a more confident result is needed.
