摘要:
The present invention is directed to compositions and methods of delivering a chemotherapeutic agent via a polynueleotide-functionalized nanoparticle (PN-NP).
摘要:
Disclosed are drug delivery compositions comprising an oligonucleotide-modified nanoparticle and a therapeutic agent. Specifically, disclosed are compositions comprising a number of oligonucleotide molecules in a ratio to therapeutic agent molecules to allow a sufficient transportation of the therapeutic agent molecules into a cell. The therapeutic agents include both hydrophobic and hydrophilic. Different attachments of therapeutic agents in a composition are also described.
摘要:
Materials and methods for modulating cellular uptake of functionalized nanoparticles are provided. Also provided are materials and methods for modulating the effectiveness of a therapeutic agent with a functionalized nanoparticle.
摘要:
The present invention concerns nanoparticles functionalized with an oligonucleotide and a domain for a variety of uses, including but not limited to gene regulation. More specifically, the disclosure provides a nanoparticle that is taken up by a cell at an efficiency different than a nanoparticle functionalized with the same oligonucleotide but does not contain a domain.
摘要:
The present invention provides structures formed from crosslinked polynucleotides, where a subset of the polynucleotides binds to a target under physiological conditions, where the signal group detectably changes upon binding.
摘要:
Disclosed are nanostructures having nanoprisms and agents, such as diagnostic and/or therapeutic agents. Nanoprisms with a surface plasmon resonance in the near-infrared convert irradiation, such as from a laser into heat selectively to allow the dissociation, such as dehybridization of oligonucleotide duplexes, of agents associated with the nanoprism surface. These nanostructures show morphological, chemical, and functional stability under hours of irradiation. Further disclosed are methods of selectively releasing agents from nanostructures after directed surface plasmon resonance mediated heating of the nanoprisms. Released agents, such as oligonucleotides, are unharmed by this process and can be repeatedly released and sequestered under spatiotemporal control.
