Different classes of nanoparticles (NPs) have been developed for controlling and improving the systemic administration of therapeutic and contrast agents.
The samples were then sonicated for 6 8 h in toluene, obtaining a suspension composed by two classes of nanoparticles.
Among the various classes of nanoparticles, metal nanoparticles are receiving much attention due to their application in various fields of science and technology.
The potential to deliver active chemotherapeutic drugs in the vicinity or directly within specific tumors via receptor mediated pathways, and to image tumors through the use of nanoparticles has been conceptually and experimentally shown for several classes of nanoparticles.
However, in this work, we show that certain classes of nanoparticles, namely lipid-coated liquid perfluorocarbon emulsions, undergo unique interactions with cells to deliver lipophilic substances to target cells without the need for entire nanoparticle internalization.
Encouraging breakthroughs, however, have been made in the last few years towards the development of new classes of nanoparticles that can respond to tumor microenvironmental conditions and successfully deliver therapeutic agents to cancer cells.
The ability of Br MSN to digest tumor ECM was assessed using matrigel and evaluated by following the release of an incorporated fluorescent dye (FITC) after treatment with the various classes of nanoparticles.
Different classes of nanoparticles, including metals, oxides, and carbon nanotubes (SiO2, TiO2, Al2O3, Al, Cu, carbon-coated copper, multiwalled carbon nanotubes, and single-walled carbon nanotubes), showed high affinity for AChE.
One unique class of nanoparticles is designed to do both, providing this way the theragnostic nanoparticles (therapy and diagnosis).
The modification and control of shape and size of this class of nanoparticles create new horizon for fascinating new applications.
