The present invention relates generally to wound closure devices comprising one or more microstructures. The devices are designed such that the microstructures are able to grip the skin or tissue surrounding a wound, optionally closing the wound, or securing the tissue or skin in place. Also provided are wound closure systems that comprise one or more microstructure wound closure devices along with other components, such as protective covers and wound healing therapeutics. A variety of packaging specifications are disclosed, as is a dispenser apparatus configured to enable simple one-handed application of the wound closure devices. Methods described herein provide for the closure of various wounds with the wound closure devices and systems.

Microstructure-based wound closure devices

Methods for forming inorganic nanostructures are provided. The methods create the inorganic nanostructures by positioning a writing electrode (e.g., a conductive 'stamp') spaced nanometers above a substrate such that a precursor is intermediate the two. Applying an electric field, a voltage bias, an ionic current, or an electronic current between the writing electrode and the substrate converts the precursor into an inorganic solid material (e.g., a semiconductor such as silicon or germanium) in the area of the writing electrode.
