The present application discloses biopolymer-based ink formulations that are useful for inkjet printing and other applications. Related methods are also disclosed.

Biopolymer-based inks and use thereof

The present disclosure relates to paper-based substrates and apparatus comprising such substrates. The apparatus may include a patterned conductive structure coupled to the paper-based substrate, wherein the patterned conductive structure responds to electromagnetic radiation.

Electronic components on paper-based substrates

The present invention provides compositions and methods for printing a predetermined pattern on silk fibroin materials using water based 'inks.' Such technique may be useful for micro- and nano-engineering applications.

Silk water lithography

The invention provides transient devices, including active and passive devices that electrically and/or physically transform upon application of at least one internal and/or external stimulus. Materials, modeling tools, manufacturing approaches, device designs and system level examples of transient electronics are provided.

Transient devices designed to undergo programmable transformations

The invention relates to silk electronic components and methods for fabricating the same. The silk electronic components can be used as novel devices, such as implantable bioelectric and/or biophotonic devices, biosensors, surveillance devices, invisible cloaks, electromagnetic concentrators or antennas.

Silk electronic components

Provided herein are silk fibroin-based photothermal elements and uses thereof. The silk fibroin-based photothermal elements comprise a plurality of plasmonic nanoparticle distributed in a silk fibroin matrix, and can generate heat when the plasmonic nanoparticles are exposed to electromagnetic radiation. The silk fibroin-based photothermal elements can be adapted to be conformable and biodegradable, and can further be integrated with various electronic components, such as a thermo-electric device for conversion of heat into electricity. The invention is useful for various in vivo applications, such as photothermal therapy, controlled drug-delivery devices or wireless powering of implanted micro-devices.

Plasmonic nanoparticle-doped silk materials

An apparatus and method are disclosed for detecting terahertz radiation at room temperature. A detecting pixel includes a sub-wavelength split-ring resonator, and is mechanically coupled to (but thermally decoupled from) a substrate via a cantilever formed from two materials that have a significant mismatch in their thermal expansion coefficients. Incident radiation causes the split-ring resonator to resonate, thereby generating heat that is transferred to the cantilever, causing the cantilever to flex. An optical readout system includes a secondary light source, such as a laser, that shines on a reflective surface on the pixel, whereby a photodiode detects the reflected light and permits calculation of a relative deflection of the pixel in the nanometer range. An exemplary detector has a noise equivalent power rating of approximately 60 pW/&#x221a;Hz.
