PROTOCELLS TO TREAT MICROBIAL INFECTION AND FOR SYNERGISTIC DELIVERY
The present disclosure relates to protocells that are useful in the treatment and prevention of viral infections, including but not limited to infections caused by a Hendra virus and Nipah virus (NiV). The present disclosure relates to protocells that are useful in the treatment of bacterial infections, including antibiotic-resistant bacterial infections. The protocells are coated with a lipid bi- or multilayer comprising at least one moiety that targets a viral cellular receptor and at least one moiety that ruptures a virally-infected cell membrane. The present disclosure further relates to novel mesoporous metal oxide nanoparticles and related protocells that are useful in the treatment and/or prevention of a wide variety of disorders, including a cancer or a bacterial or viral infection. Such nanoparticles and protocells can be functionalized to allow for synergistic loading of a wide variety of active ingredients.
DETECTING AN ANALYTE
Provided herein is a method for detecting an analyte in a sample, which includes contacting the analyte with a nanoparticle having a core, a pore extending radially from said core, a binding agent for binding the analyte and a detection agent immobilized within the pore. A kit including such a nanoparticle and a method of generating a nanoparticle displaying an anchoring group is also provided. In addition, provided herein is a composition including a nanoparticle having a core and a radially extending pore having quantum dots immobilized therein that is dispersed in and/or on a substrate. Also provided are products, such as a display device, a LED device and a solar cell, that include the composition as well as methods of using and making said composition.
Concentration-dependent self-interaction assay
Methods for producing high concentration protein formulations having high stability are provided. Assays for selecting proteins and formulation conditions that have high self-repulsive attributes are used as an early step in the manufacturing process. Specifically, a protein concentration-dependent self-interaction nanoparticle spectroscopy method is employed as a protein colloidal interaction assay.
Nanocomposite and uses thereof
Disclosed herein is a nanocomposite comprising a core-shell nanoparticle and a core-shell quantum dot. The core-shell nanoparticle comprises a phosphor core, a shell layer, and a cleavable peptide. The core-shell quantum dot comprises a center core, an intermediate layer, an outer layer, a silica layer, and an arginylglycylaspartic acid (RGD) peptide. The core-shell nanoparticle and the core-shell quantum dot are linked to each other via forming a peptide bond between the cleavable peptide and the RGD peptide. Also disclosed are the uses of the nanocomposite in making a diagnosis of tumors.
Near-infrared fluorescent nanoprobe
A fluorescent probe having a capsule of nanometric size and an aggregate of fluorogenic molecules coupled to the capsule is provided. The aggregate emits a fluorescent signal at one or more wavelengths within the fluorescence spectral range when the probe is illuminated by an excitation light beam at one or more wavelengths within the excitation spectral range. Preferably, the fluorescent spectral range is in the near-infrared region of the spectrum. In some embodiments, the capsule is a boron nitride (BN) nanotube and the aggregate comprise 3,6-Bis[2,2]bithiophenyl-5-yl-2,5-di-n-octylpyrrolo[3,4-c]pyrrole-1,4-dione as fluorogenic molecules. In some embodiments, the 3,6-Bis[2,2]bithiophenyl-5-yl-2,5-di-n-octylpyrrolo[3,4-c]pyrrole-1,4-dione fluorogenic molecules are in a J-aggregation state.
Rotors for immunoassays
The present invention provides an analyte detection system for detecting target analytes in a sample. In particular, the invention provides a detection system in a rotor or disc format that utilizes a centrifugal force to move the sample through the detection system. Methods of using the rotor detection system to detect analytes in samples, particularly biological samples, and kits comprising the rotor detection system are also disclosed.
