Methods of synthesizing gold nanodendrites (AuNDs) using amines, such as long chain amines, as a structural directing agent are disclosed. Degree of branching (DB) of the AuNDs can be tuned by adjusting certain synthetic parameters, such as solvent type, and the type and concentration of the long chain amines. DB control results in dramatic tunability of the optical properties of the AuNDs in the near infrared (NIR) range enabling improved performance, for example as a photothermal cancer therapeutic.

A photocaged DNA nano-tweezer and methods of using said photocaged DNA nano-tweezer are described. In particular, provided herein is a DNA nano-tweezer comprising a hairpin with a single-stranded loop that comprises a first arm and a second arm; and a trigger strand complementary to the single-stranded loop and comprising at least one photocaged residue with a protecting group.

The present disclosure relates to quantum dot nanoparticles useful for targeting and manipulating mitochondrial function, and to methods of targeting and manipulating mitochondrial function using such quantum dot nanoparticles.

An intracellular delivery system and method are provided. The intracellular delivery system comprises a laser-activated surface and cells positioned at a distance from the laser-activated surface. A laser provided a laser pulse that is used to porate membranes of the cells to deliver or extract cargo from the cells into a liquid surrounding the cells. The method of intracellular delivery comprises positioning a laser-activated surface at a distance from cells and applying a laser pulse from the laser to the surface to porate membranes of the cells to deliver or extract cargo from the cells into a liquid surrounding the cells.

A targetable nanoconstruct capable of simultaneously serving as a therapeutic platform for photodynamic therapy as well as an MR molecular imaging agent, free of heavy metal atoms. F3-cys targeting agent nanoconstructs, including 8PEGA-Ce6 NCs. A label-free 8PEGA nanoconstruct that can be directly and selectively imaged by MRI, using standard spin-echo imaging sequences with large diffusion magnetic field gradients to suppress the water signal.

Antibodies and meditopes that bind to the antibodies are provided, as well as complexes, compositions and combinations containing the meditopes and antibodies, and methods of producing, using, testing, and screening the same, including therapeutic and diagnostic methods and uses.
