    Abstract: Microstrip patch antenna (46), feed structure (48), and matching circuit (50) designs for an RFID tag (10). A balanced feed design using balanced feeds coupled by a shorting stub (56) to create a virtual short between the two feeds so as to eliminate the need for physically connecting the substrate to the ground plane. A dual feed structure design using a four-terminal IC can be connected to two antennas (46a,46b) resonating at different frequencies so as to provide directional and polarization diversity. A combined near-field/far-field design using a microstrip antenna providing electromagnetic coupling for far-field operation, and a looping matching circuit providing inductive coupling for near-field operation. A dual-antenna design using first and second microstrip antennas providing directional diversity when affixed to a cylindrical or conical object, and a protective superstrate (66). An annular antenna (46c) design for application to the top of a metal cylinder around a stem.

    Abstract: Commercially feasible methods for synthesizing various epothilones precursors needed for the preparation of final epothilones are provided, including techniques for the synthesis of epothilone segment A and C precursors. Segment C precursors are prepared using starting nitriles, which can alternately be oxidized to ketones and converted, or reacted to form the diol with subsequent conversion to the segment. Segment A precursors are prepared by reacting a starting enone with a chiral catalyst to give an intermediate alcohol in high enantomeric excess, followed by conversion of the alcohol to the desired Segment A precursor.

    Abstract: A capture device for capturing a biological substance can include: a substrate; a graphene-oxide layer on the substrate; at least one polydopamine polymer coupled with the graphene-oxide; and at least one targeting receptor coupled to the polydopamine(s), wherein the targeting receptor is capable of targeting/binding with a target biological substance. The graphene-oxide may be covalently coupled with the substrate and polydopamine, and the polydopamine may be covalently coupled with the targeting receptor. The targeting receptor can be an antibody or fragment thereof. The target biological substance can be an exosome. The substrate can be a particle (e.g., magnetic, such as magnetically responsive) or a surface in a microfluidic channel. The surface can be a top surface of a post, the post having a Y-shaped cross-sectional profile. In one aspect, the substrate is a particle. The capture device can include the target biological substance bound to the targeting receptor.
