Particles for Delivery of Proteins and Peptides
The present application provides a method of making a particle comprising (i) obtaining a first solution comprising a negatively charged polysaccharide; (ii) obtaining a second solution comprising a positively charged polysaccharide; and (iii) mixing the first solution and the second solution to obtain a suspension comprising the particle. The present application also provides a method of making a therapeutic particle, comprising: (i) obtaining a solution comprising a therapeutic protein; (ii) obtaining a first suspension comprising the particle comprising a negatively charged polysaccharide and a positively charged polysaccharide, and (iii) mixing the solution of the therapeutic protein and the first suspension to obtain a second suspension comprising the therapeutic particle. The present application also provides particles (e.g., therapeutic particles) prepared by any one of the disclosed methods, as well as the compositions comprising such particles, and methods of treating a disease or condition using such particles and compositions.
MULTI-COMPONENT NANOCHAINS
A multi-component nanochain for use in diagnostic and therapeutic applications includes at least three nanoparticles linked together to form the nanochain. At least one nanoparticle of the nanochain has an asymmetric surface chemistry defined by asymmetrically disposed first linkers and second linkers. The nanoparticles are linked to form the nanochain by linking first linkers and/or second linkers disposed on separate nanoparticles.
Magnetic particle control and visualization
Some embodiments provide a system for external manipulation of magnetic nanoparticles in vasculature using a remotely placed magnetic field-generating stator. In one aspect, the systems and methods relate to the control of magnetic nanoparticles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow.
Virus-PCION complex having enhanced antitumor effect by using electromagnetic field
The present disclosure relates to a composition for transduction of a virus in a cell by using a crosslinked product of PEGylated magnetic nanoparticles and catechol grafted poly-L-lysine by application of an external magnetic field. When the composition is used, a virus may be delivered into cells more rapidly and efficiently than in intracellular uptake of a virus by CAR-mediated endocytosis.

NOVEL BSH COMPLEX FOR BORON NEUTRON CAPTURE THERAPY
The present invention provides: a complex of a mercaptoundecahydrodecaborate (BSH) and a peptide, the complex for boron neutron capture therapy (BNCT); a method for producing the complex; and a cancer therapy using the complex.
Nanostructured carriers for guided and targeted on-demand substance delivery
Methods, systems, and devices are disclosed for fabricating and implementing nanoscale and microscale structured carriers to provide guided, targeted, and on-demand delivery of molecules and biochemical substances for a variety of applications including diagnosis and/or treatment (theranostics) of diseases in humans and animals. In some aspects, a nanostructure carrier can be synthesized in the form of a nanobowl, which may include an actuatable capping particle that can be opened (and in some implementations, closed) on demand. In some aspects, a nanostructure carrier can be synthesized in the form of a hollow porous nanoparticle with a functionalized interior and/or exterior to attach payload substances and substances for magnetically guided delivery and controlled release of substance payloads.
Devices for controlling magnetic nanoparticles to treat fluid obstructions
A system for the physical manipulation of free magnetic rotors in a circulatory system using a remotely placed magnetic field-generating stator is provided. In one embodiment, the invention relates to the control of magnetic particles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow. Examples of vascular occlusions targeted by the system include, but are not limited to, atherosclerotic plaques, including fibrous caps, fatty buildup, coronary occlusions, arterial stenosis, restenosis, vein thrombi, arterial thrombi, cerebral thrombi, embolisms, hemorrhages, other blood clots, and very small vessels.
Targeted shell for use in drug delivery system utilizing carbosilane dendrimer
The present invention is related to a targeted type shell for drug delivery system. The object of the present invention is to provide the targeted type shell for DDS, which comprises a carbosilane dendrimer containing a silole produced by which is formed by utilizing the reaction between thiol group and alkyl halide, and a targeted protein containing a labeled proteins such as green fluorescent protein with a target recognition site. The shell may incorporate compounds having a variety of molecular weight and biopolymers, and selectively deliver them into targeted cells.
