| 20110165022 | HYDROPHILIC DIAGNOSTIC DEVICES FOR USE IN THE ASSAYING OF BIOLOGICAL FLUIDS - Diagnostic in-vitro devices for use in the assaying of biological fluids are provided which include cover plates or backing strips which exhibit hydrophilic properties to assist in transport of the biological fluid or retention of same within the device. Exemplary diagnostic devices include lateral flow devices, microfluidic devices and microtiter plates. The devices may also be comprised of low fluorescent material in order to facilitate any diagnostic determination by use of fluorescent emissions. Hydrophilic properties may be imparted to the cover plates or backing strips by physical or chemical treatment thereof. The cover plates or backing strips may exhibit heat sealable or pressure sensitive properties. | 07-07-2011 |
| 20110111240 | ACRYLIC BASED PRESSURE SENSITIVE ADHESIVE FORMULATION - An adhesive formulation is disclosed that includes (a) a pre-polymerized cross-linkable non-water soluble acrylic based pressure sensitive adhesive, (b) a cross-linking agent selected from the group consisting of metal chelates, silanes, epoxy-functional compounds, aziridine compounds, multifunctional amines, alkyl halide compounds, multifunctional acids, multifunctional mercaptans, multifunctional epoxy compounds, polyols in the presence of a catalyst, and combinations thereof and (c) a polyol having a weight average molecular weight in the range from 1,000 g/mol to 10,000 g/mol. When cured, the adhesive formulation is self-wetting and has a peel strength less than 20 oz/in. | 05-12-2011 |
| 20100068820 | MOLECULARLY IMPRINTED POLYMER AND USE THEREOF IN DIAGNOSTIC DEVICES - An adhesive is provided containing at least one synthetic polymer with receptor sites that enable the selective capture or release of a target molecule. A polymer is synthesized by polymerizing and cross-linking a functional monomer or functional copolymers in the presence of a target or template molecule allowing for reversible interactions between the polymer and the target molecule. The target molecule may be extracted from the polymer creating receptor sites complimentary to the target molecule. Alternatively, the target molecule may remain in the polymer network and be controllably released. The molecularly imprinted polymer is formulated into an adhesive. The adhesive can be used as a component in an in-vitro diagnostic device to release template molecules or to capture target molecules in vacated receptor sites in the synthetic polymer. | 03-18-2010 |
| 20090092819 | POROUS PRESSURE SENSITIVE ADHESIVE AND TAPES - A pressure sensitive adhesive includes a substantially continuous polymer phase having pressure sensitive adhesive properties, and a plurality of pores arranged within the substantially continuous polymer phase and disposed to permit fluid to pass from a first side through at least a portion of the plurality of pores to a second side. The plurality of pores is substantially resistant to cold flow. A method of forming a porous pressure sensitive adhesive tape includes providing a solution for forming an adhesive having pressure sensitive adhesive properties, the solution including a pore forming material, casting a film comprising the solution, laminating a liner on the film, and exposing the adhesive to an energy source to form pores in the adhesive and cure the adhesive to form the pressure sensitive adhesive tape. | 04-09-2009 |

| 20090029100 | METHOD FOR PRODUCING RIGID LAMINATES FOR OPTICAL APPLICATIONS - A method for fabricating a rigid lamination. The method includes providing a first rigid substrate, disposing an adhesive on a surface of the first rigid substrate and disposing a second rigid substrate on at least a portion of the adhesive. The second rigid substrate has a first end and a second end. The second rigid substrate is heated to a substantially uniform temperature, where the temperature is sufficient to melt the adhesive. A non-uniform pressure is applied to a surface of the second rigid substrate. The non-uniform pressure includes a lesser pressure and a greater pressure, where the greater pressure is applied at the first end of the second rigid substrate and is sufficient to impart adhesive flow in a direction toward the second end. The pressure is controllably increased along at least a portion of the surface between the first end and the second end, where the increase is controlled to drive the adhesive flow in the direction toward the second end until the pressure applied is substantially uniform across the surface and the adhesive between the first rigid substrate and the second rigid substrate is substantially free of entrained gas bubbles. The adhesive is cooled to form a rigid lamination having adhesive substantially free of entrained gas bubbles. | 01-29-2009 |
