Abstract: The disclosure provides, inter alia, compositions including cell-nanoparticle constructs and drug loaded nanoparticles, and methods for their use in the treatment of cancer. Also provided are unmodified cisplatin molecules encapsulated by silica nanoparticles, and their use in the treatment of cancer.

Abstract: Disclosed herein, inter alia, are compositions and methods of modulating macrophage activity. Provided is a method of treating a disease (e.g., a macrophage-associated disease, autoimmune disease, inflammatory disease, or a cancer of an organ in the intraperitoneal cavity), the method including intraperitoneally administering to a subject in need thereof a therapeutically effective amount of a nanoparticle composition or pharmaceutical composition. Provided is a silica nanoparticle non-covalently bound to a plurality of nucleic acids, wherein the silica nanoparticle has a net positive charge in the absence of the plurality of nucleic acids. Provided is a pharmaceutical composition including a nanoparticle composition as described herein, and a pharmaceutically acceptable excipient.

Abstract: Provided herein are functionalized nanoparticle compositions and methods of using the same. The functionalized nanoparticles provided include a nuclease cleavage site and are, inter alia, useful for the formation of nanoparticle aggregates and detection of nuclease activity through nanoparticle aggregate formation.

Abstract: Provided herein are encoded split pool libraries useful, inter alia, for forming highly diverse and dense arrays for screening and detection of a variety of molecules.

Abstract: Disclosed herein, inter alia, are methods for detecting cancer using nanoparticles.

Abstract: Disclosed herein, inter alia, are nanoparticle compositions (e.g., silica nanoparticles) including insoluble drug nanocrystals and methods of using the same for treating cancer.

Abstract: A magnetic field controlled guidestar for focusing light deep inside scattering media using optical phase conjugation. Compared with the optical and ultrasonic field, the magnetic field has an exceptional penetration depth. The magnetic particle guidestar has a high light-tagging efficiency, good biocompatibility, and a small diameter which enables a sharp and bright focusing deep inside biological tissue. This new method can benefit a wide range of biomedical applications including deep-tissue imaging, neural modulation, and targeted photothermal and photodynamic therapies.
