Abstract: This disclosure pertains to a testing method for a target pathogen. The method uses biosensors with particular fluorescence characteristics, such that when the biosensor binds to a target pathogen, a fluorophore may emit light if excited. The biosensor may be an aptamer-based biosensor with a fluorophore reporter and a quencher. The excitation of the fluorophore and the detection of fluorescence may be made through the use of a flashlight source and a camera from a mobile device, such as a smartphone.

Abstract: The invention is concerned with a support prosthesis for a natural human heart valve having an annulus of generally oval configuration with a major axis and a minor axis and at least two leaflets stemming from the annulus and each moving along a naturally preordained path during systolic contraction or diastolic expansion. The support prosthesis according to the invention consists of an oblong, annular flexible member of a size and shape to fit against the annulus, the member having a longitudinal axis and being made of a biocompatible material exhibiting elasticity only along the longitudinal axis so as to permit dilatation of the annulus along the major axis thereof, in response to heamodynamic and functional changes, while preventing dilatation of said annulus along the minor axis thereof so that the path along which each said leaflet travels remains unaltered. Because of its pliable nature, the support prosthesis of the invention does not produce a systolic anterior motion of the mitral valve.
