The present disclosure relates to PEGylated surface, in particular nano-sized carriers with such surface, in medical applications, such as a drug delivery system. Particularly, the PEGylated nano-sized carriers may solve the immunological issues caused by or related to polyethylene glycol-containing substances.

Described herein are nanoparticle-based compositions, kits and methods and platforms for delivering one or more nucleic acids to a cell.

The present invention relates to the field of nanotechnology, in particular, to the production of biodegradable polymeric nanoparticles. The present invention provides a biodegradable polymeric nanoparticle made up of a block copolymer and a process for producing the same. The nanoparticles are produced without the use of any emulsifiers and have a size ranging from 30-120 nm. The methods of controlling the drug loading capacity are disclosed along with the process of producing entity-loaded nanoparticles. Compositions comprising the nanoparticles and their use in therapeutics, diagnostics and theranostics are also disclosed.

The invention relates to polymer nanoparticle and DNA nanostructure delivery compositions for non-viral delivery, and methods therefor. More particularly, the invention relates to polymer nanoparticle delivery compositions, such as reversible addition-fragmentation chain transfer (RAFT) polymer compositions, and DNA nanostructure delivery compositions, such as DNA origami compositions, for the delivery of more than one payload, or for the delivery of a nucleic acid construct payload of 3 kB or more, and methods therefor.

A composition comprising an amphiphilic polymeric material that is both hydrogen peroxide- and hypoxia-sensitive is described. The composition can further include a glucose-oxidizing enzyme and insulin, a bioactive derivative thereof, and/or another therapeutic agent (e.g., another diabetes treatment agent). The polymeric material can form vesicles that comprise single or multiple layers of the polymeric material that enclose the glucose-oxidizing enzyme and the insulin, bioactive derivative and/or other therapeutic agent. The vesicles can be loaded into microneedles to, for example, prepare microneedle arrays for skin patches. Methods of delivering insulin to a subject using the compositions, vesicles, microneedles, and/or microneedle array skin patches are also described.

Described herein are hybrid nanoparticles that are exosomes loaded with one or more nanoparticle dendrimers. Also included are pharmaceutical compositions including the hybrid nanoparticles and methods of making the hybrid nanoparticles. Also described is a method of treating a human subject by administering to the human subject the above-described hybrid nanoparticles.

Described herein is a nanoparticle system including a multivalent nanoparticle core having a plurality of β-hairpin peptides conjugated thereto. Also included are pharmaceutical compositions and methods of making the nanoparticle system. Further included are immunotherapy methods including administering the nanoparticle system to a subject in need thereof, such as a human cancer patient.

A combination therapy involving different therapeutic molecules can enhance and improve the therapeutic potentials. An effective therapeutic strategy conjugates silica (SiO.sub.2) nanoparticles with, e.g., 3-glycidyloxypropyl, trimethoxysilane and azoles, e.g., 1,2,4-triazole (Tri), 3-aminotriazole (ATri), 5-aminetetrazole (Atet), imidazole (Imi). These exemplary materials—classified as SiO.sub.2-3GPS-Tri (Conj. 1), SiO.sub.2-3GPS-Atri (Conj. 2), SiO.sub.2-3GPS-Atet (Conj. 3), SiO.sub.2-3GPS-Btri (Conj. 4), and SiO.sub.2-3GPS-Imi (Conj. 5)—can amplify targeting of therepeutics for human colorectal carcinoma cells (HCT-116), enhancing anti-cancer effects.

In an embodiment, the present disclosure relates to a targeting platform that includes a targeted delivery system including an agent. In some embodiments, the targeted delivery system is modified by fluorination. In some embodiments, the targeted delivery system is electrically charge neutral. In a further embodiment, the present disclosure relates to a method that includes fluorinating a targeting compound with a fluorinating reagent and loading an agent with the fluorinated targeting compound to thereby form a micelle. In an additional embodiment, the present disclosure relates to a targeting platform that includes a fluorinated polymeric system including an agent. In another embodiment, the present disclosure relates to a method that includes fluorinating a targeting compound with a fluorinating reagent and loading an agent with the fluorinated targeting compound to thereby form a micelle. Additionally, the method can include administering the fluorinated targeting compound to a subject.

Provided herein are compositions comprising nanoparticles, wherein the nanoparticles comprise at least one payload, wherein the nanoparticles further comprise at least one surface bound functional group and method of their use.
