Abstract: The present invention relates to methods and compositions for detecting analytes, including proteins, polysaccharides, viruses, nucleic acids and cells. The methods and compositions utilize a reporter probe, suitably a multivalent reporter probe, to detect the presence of the analytes. In embodiments, the methods and compositions can be used for non-enzymatic detection of nucleic acids.

Abstract: Engineered protein coatings are provided for medical implants to promote bone regeneration. The coating is an engineered protein containing an elastin-like structural domain (SEQ ID No: 2) and a cell-adhesive domain derived from an extended fibronectin RGD sequence. The surface of the medical implant is covalently and directly bonded to the coating via photoreactive crosslinking through an insertion and/or addition reaction. The engineered protein coating can be applied directly upon fabrication of the implant, which would eliminate applying the coating in the operating room. The engineered protein coating is also customizable and can include biologics to improve performance. Furthermore, the engineered protein coating could also be spatially patterned on the implant surface.

Abstract: Disclosed are methods and compositions for detecting analytes, including proteins, polysaccharides, viruses, nucleic acids and cells. The methods and compositions utilize a reporter probe, suitably a multivalent reporter probe, to detect the presence of the analytes. The methods and compositions can be used for non-enzymatic detection of nucleic acids.
