A soft conductive composition can include: a crosslinked silicone composition; and single-walled or multi-walled carbon nanotubes in the silicone composition. A neural probe or other implant can include the soft conducive composition on a least a portion of the implant body. A method of making an implant can include: selecting PDMS precursors; cross-linking the PDMS precursor to obtain an elastic modulus of about 3-9 kPa or +/&#x2212;1%, 5%, 10%, 20%, or 50%; selecting the carbon nanotubes; introducing the carbon nanotubes into the crosslinked PDMS to form a soft conductive composite composition; and coating the soft conductive composite composition onto at least a portion of an implant. A method of measuring properties at a neural interface can include: providing a neural probe having a soft conductive composition; implanting the neural probe having the soft conductive composition at a neural interface; and measuring a property with the neural probe.

Ultra-soft coatings for interfaces with brain and other soft tissues

Described herein are methods and compositions for high efficiency transfection of siRNA into a cell population. Such methods and compositions utilize a low voltage pre-conditioning pulse to modulate the efficiency of siRNA transfection. In some embodiments, the methods and compositions permit spatial and temporal control of siRNA transfection efficiency within a population of cells. The disclosed methods and compositions, in some embodiments, are amenable to high throughput applications such as siRNA library-based phenotypic screening.
