Publication number: 20060251880Abstract: The invention provides an absorbent material or article comprising an absorbent hydrogel composite sheet. The sheet includes an absorbent layer part having two major faces which comprises a flexible plasticised hydrophilic polymer matrix having an internal cellular structure, and a second part which comprises a flexible plasticised hydrophilic polymer matrix having a relatively continuous internal structure. The second part may be associated with the layer part such that the second part infiltrates some but not all of the cellular voids of the absorbent layer part over a major face of the absorbent layer part. Alternatively, the second part may be associated with the layer part such that the second part overlies a major face of the absorbent layer part. By this arrangement, some but not all of the absorbent layer part is effectively exposed for absorption of external water or other fluid through the side of the sheet corresponding to that said major face of the absorbent layer.Type: ApplicationFiled: November 23, 2005Publication date: November 9, 2006Inventors: Hugh Munro, Philip Andrews, Susana Sainz Garcia

Patent number: 6127120Abstract: The invention relates to the detection of target nucleic acids or nucleic acid units in a sample, by obtaining a SER(R)S spectrum for a SER(R)S-active complex containing, or derived directly from, the target. The complex includes at least a SER(R)S-active label, and optionally a target binding species containing a nucleic acid or nucleic acid unit. In this detection method, the concentration of the target present in the SER(R)S-active complex, or of the nucleic acid or unit contained in the target binding species in the SER(R)S-active complex, is no higher than 10.sup.-10 moles per liter. Additionally or alternatively, one or more of the following features may be used with the method: i) the introduction of a polyamine; ii) modification of the target, and/or of the nucleic acid or nucleic acid unit contained in the target binding species, in a manner that promotes or facilitates its chemi-sorption onto a SER(R)S-active surface; iii) inclusion of a chemi-sorptive functional group in the SER(R)S-active label.Type: GrantFiled: April 21, 1998Date of Patent: October 3, 2000Assignee: University of StrathclydeInventors: Duncan Graham, Adrian Matthew Thornton Linacre, Callum Hugh Munro, William Ewan Smith, Nigel Dean Watson, Peter Cyril White
