Pressure
Sensitive Adhesives in Medical, In-Vitro, and Molecular
Diagnostic Devices
Pressure
Sensitive Adhesives (PSA) and functional coatings are increasing
being used in the assembly of devices and components.
Additionally, the adhesives are becoming sophisticated where
these also play an active role in the actual functioning of the
device.
Adhesives
Research Inc. is a leading developer and manufacturer of
high-performance pressure-sensitive adhesive tapes, specialty
coatings, films and laminates.

 These products
find uses in a variety of medical device applications including
membrane based IVD and molecular diagnostic testing, advanced
wound care, lab-on-a-chip, microplate sealing, molecular
technology, and transdermal drug delivery. Special requirements
of some of these markets have forced us develop designer
adhesives where not only the strength and quality of the bond is
important but also where it adds value to the performance of the
final device.
Ease of
handling, allowing for a roll-to-roll continuous process in
manufacturing, formation of well defined bond line, achieving an
instant bond, wide choice of available chemistries and
constructions are some of the advantages PSAs provide. This
presentation will discuss the basic attributes of PSAs. Then the
presentation will transition to the applications. Examples
include electrically conductive adhesives as an active electrode
in electrochemical biosensors. Hydrophilic coatings assist in
the flow and filling of channels in microfluidic devices. Porous
adhesives for high end woundcare applications, lateral flow,
vertical flow and flow-through assays. Hydrogel systems to meet
the needs of advanced woundcare and active transdermal drug
delivery systems. Dissolvable films are being explored as a
means of delivering reagents to in-vitro diagnostic devices.
Special adhesives are targeted for sealing of microplates used
in molecular diagnostics such as high throughput screening,
RT-PCR, protein crystallization, drug discovery, cell culture
and compound storage. These exhibit superior optical clarity,
low autofluorescence, low birefringence, excellent solvent and
temperature resistance. |
