Abstract: The invention encompasses hydrogels, monomer precursors of the hydrogels, methods for the preparation thereof, and methods of use therefor. The linking of monomers can take place using non-radical, bioorthogonal reactions such as copper-free click-chemistry.

Abstract: The invention provides a method for preparing an expanded cell or tissue sample suitable for microscopic analysis. Expanding the sample can be achieved by binding, e.g., anchoring, key biomolecules to a DMAA-TF polymer network and swelling, or expanding, the polymer network, thereby moving the biomolecules apart as further described herein. As the biomolecules are anchored to the polymer network isotropic expansion of the polymer network retains the spatial orientation of the biomolecules resulting in an expanded, or enlarged, sample.

Abstract: An asset tracking device and method for detecting the presence of an intermodal shipping container and responsively selecting a preferred location determination. The device may include a controller, a sensor coupled to the controller, a global navigation satellite system chip, and a cellular signal transceiver. While not detecting a container, the controller obtains location data via a global satellite system chip. While a container is detected, the sensor sends a detection signal to the controller and, responsive to the detection signal, the controller obtains location data from a cellular signal transceiver and not from the global satellite system chip.

Abstract: Apparatus and methods for imaging and tracking of nano- and micro-scale objects with acceptable latency for relevant medical procedures, such as delivery of therapeutic payload or minimally invasive surgery are disclosed, including the capability to superimpose accurate anatomical data over a tracking image. Software applications are provided for data logging via a remote-control station; and software interface with remote motion control mechanism, controlling the motion of internal device.
