  • Manufacture of biosensors by continuous web incorporating enzyme humidification
    Publication number: 20080053321
    Abstract: The present invention is directed to an improvement to the current method of printing test sensors using a continuous web of substrate material. The improved method includes incorporating a means of retaining the high water content of the enzyme print material by maintaining relative humidity levels around the enzyme print station. More particularly, the method according to the present invention involves a method wherein said air in said laminar flow has a relative humidity of approximately 91%.

  • Sensors for detecting an analyte using silver nanoparticles
    Publication number: 20060286684
    Abstract: A sensor comprises silver nanoparticles in which substantially all of the surfaces of the silver nanoparticles are available for interaction with an analyte or for functionalisation with a receptor which is capable of interacting with an analyte. Silver nanoparticles are preparated by forming the nanoparticles in the presence of a polymeric stabiliser such as PVA.

  • Spinal support plates
    Patent number: 5647872
    Abstract: A spinal plate is provided that has two components of curvature in the lower surface that opposes the spinal vertebrae. This lower surface preferrably has the shape of a toroidal segment. A series of plates may be taken from a principal "s"-shaped template of similar shape on its lower surface. For convenience of manufacture, the shape of the curvature of the "S"-shaped template along the sides of the template is circular. A special hole pattern is also disclosed in respect of a tapered thoracic portion of the template.
