Abstract: Systems and methods which provide anti-counterfeiting patterns tagged with multi-mode nanotaggants, such as may comprise single-mode nanoparticles, multi-mode nanoparticles, or a combination thereof, are described. The multi-mode nanotaggants of embodiments are configured to exhibit prescribed emissions by excitation at distinct stimulus wavelengths. Decryption of anti-counterfeiting patterns tagged with multi-mode nanotaggants of embodiments of the invention may be achieved by examining temporal color responses of the pattern to varying illuminations. In addition to the various color codes that may be encrypted into an anti-counterfeiting pattern using nanotaggants, embodiments provide various graphic codes that may be encrypted into anti-counterfeiting patterns. Such graphic codes may not only comprise the graphic pattern of the anti-counterfeiting pattern itself, but one or more graphic patterns of nanotaggants of the anti-counterfeiting pattern.

Abstract: An array of magnetic nanoparticle (MNP) spin torque oscillators (STOs) is described. Each STO is comprised of a uniform, chemically synthesized, spherical nanoparticle which couples to current flowing along a surface. The particles are organized into an array by a self-assembly technique with uniform spacing and close proximity to allow strong electrical and magnetic coupling between particles. The coupling of the nanoparticles to the surface current drives the oscillations by spin-torque, and for phase locking and data input. The uniform, spherical shape of the particles allows the oscillations to be achieved at low currents and with low power dissipation. The MNP-STOs may be used as a basis for massively parallel computing, microwave oscillators, or other applications.

Abstract: The present invention generally relates to microfluidics and labeled nucleic acids. For example, certain aspects are generally directed to systems and methods for labeling nucleic acids within microfluidic droplets. In one set of embodiments, the nucleic acids may include “barcodes” or unique sequences that can be used to distinguish nucleic acids in a droplet from those in another droplet, for instance, even after the nucleic acids are pooled together. In some cases, the unique sequences may be incorporated into individual droplets using particles and attached to nucleic acids contained within the droplets (for example, released from lysed cells). In some cases, the barcodes may be used to distinguish tens, hundreds, or even thousands of nucleic acids, e.g., arising from different cells or other sources.

Abstract: A pluggable trust architecture addresses the problem of establishing trust in hardware. The architecture has low impact on system performance and comprises a simple, user-supplied, and pluggable hardware element. The hardware element physically separates the untrusted components of a system from peripheral components that communicate with the external world. The invention only allows results of correct execution of software to be communicated externally.

Abstract: A polymerizable unit that yields an electrochemically responsive polymer (advantageously pyrrole) is anchored by polymerization within a polycaprolactone matrix to form an electroactive scaffold upon which cells can be cultured and in which the micro- and nano-topological features of the polycaprolactone matrix are preserved. A scaffold manufactured in accordance with the preferred embodiment can support Schwann cells, which produce nerve growth factor when electrically stimulated. Nerve growth factor has been demonstrated to promote the regeneration of nerve tissue. By implanting the scaffold on which Schwann cells have been cultured into damaged nerve tissue and applying a voltage across the scaffold, nerve growth factor is produced, thereby promoting repair of the damaged nerve tissue.
