Abstract: Fluorescent bimetallic nanocomposites (M1@M2-NCs) of silver-gold (Ag@Au-NC) and silver-platinum (Ag@Pt-NC) are prepared by reducing silver nitrate (AgNO3) on gold nanoparticles (AuNPs) and platinum nanoparticles (PtNPs) using sodium borohydride (NaBH4) at alkaline pH=11, in the presence of a lysozyme that acts as a template, and in the presence of a capping and stabilizing agent. The biocompatible bimetallic nanocomposites (M1@M2-NCs) have promising multifunctional applications (cell imaging, bio-sensing, therapeutics) observed by both in vitro as well as in vivo experiments. The fluorescent bimetallic nanocomposites (M1@M2-NCs) of silver-gold (Ag@Au-NC) and silver-platinum (Ag@Pt-NC) may be useful as an alternative nanomedicine in cancer theranostics applications.

Abstract: Provided herein are high-throughput methods for genetic barcoding and analysis, e.g., for tagging each biomaterial apsule with a barcode cell. These barcode cells are derived from patient samples, and thus embody natural human genetic variation. Also provided are SNP panels that can be used as genetic barcodes to identify the identity of a cell.

Abstract: The present disclosure relates to implantable constructs designed to deliver antigenic therapeutic reagents to a subject while providing protection from host immune responses. In certain aspects, the constructs are designed to degrade over time or upon a particular signal, thereby providing control of the length of time the therapeutic agent is delivered to the subject.

Abstract: The disclosure describes new devices and methods for vascularizing devices and methods for implanted diagnostics and therapeutics. The present disclosure provides, in certain embodiments, a device containing a degradable shell and a non-degradable core. In certain embodiments, the non-degradable core can include encapsulated therapeutic cells and/or biosensors, wherein the degradable shell serves as a scaffold for blood vessel growth, resulting in enhanced blood flow to the cells and/or biosensors.

Abstract: The current invention relates to development of new formulation containing gold nanoparticles (AuNPs) with bi-functional recombinant fusion proteins TRAF(C) for the delivery of anticancer drugs and nucleic acids to HER2+ cancers. Using the combinatorial approach, we designed gold nanoparticle-based targeted drug delivery system (TDDS) or (Au-TR-DX-si) by combining AuNPs with bi-functional recombinant fusion protein TRAF(C) (TR), doxorubicin (DX) and siRNA (si). The recombinant protein based gold nanoparticles formulations are stable and homogenous as revealed by several physicochemical studies. In addition, the engineered fusion protein TRAF (C) has the ability to target selectively to HER2+ receptors overexpressed in ovarian cancer cells (SK-OV-3).

Abstract: The present invention relates to highly biocompatible or nontoxic PVP (poly(n-vinyl-2-pyrrolidone) coated silver prussian blue nanoparticles (SPB-NPS: Ag3[Fe(CN)6] where PVP acts as stabilizing or capping agent. The as-synthesized nanoparticles (SPB-NPs) have been thoroughly characterized by several analytical tools. The SPB-NPs are highly stable for more than two weeks towards different physiological buffers or solutions with different pH (pH=6, ?7.4 & ?8). These nanoparticles (SPB-NPs) exhibit biocompatibility towards various normal cells (HUVEC, CHO, & ECV304) but show significant inhibition of proliferation of different cancer cells in vitro and tumor growth in C57/BL6/J mice model (aggressive murine melanoma cancer model: B16F10). Additionally, the SPB-NPs show excellent antibacterial activity towards gram-negative (E. coli) and gram-positive (B. subtilis) bacteria.

The composite dielectric material is doped with nano-crystalline rare metal oxide which is embedded in silicon dioxide glass matrix, and the composite dielectric material of the nano-crystalline rare metal oxide and the silicon dioxide glass matrix is synthesized by the manufacturing method using sol-gel route. The dielectric value of the glass composite dielectric material is greater than that of pure rare metal oxide or that of silicon dioxide. In presence of magnetic field, the dielectric value of the composite dielectric material is substantially enhanced compared with that of the composite dielectric material at zero field.
