  • Publication number: 20100261265
    Abstract: This invention provides a method and device for testing cell responses to polymer particles in vitro. Cells and culture medium are added to a 24-well plate and incubated for 24 hours to make the cells adhere to the interior bottom surface of the plate. The old medium is then drained out and fresh medium and polymer particles are added to fill up the wells. The plate was covered with a light and transparent film such as polyvinyl chloride (PVC) with small holes for ventilation and inverted carefully. The polymer particles float and contact with the cells adhered to the interior bottom surface of the plate. Then the cells are incubated for an intended period for further experiments.

  • Publication number: 20070281032
    Abstract: In a method for generating polymeric wear particles for use in animal experiments as polymeric medical implant pre-clinical testing, microfabrication technique is used to design different mask patterns and obtain a uniformly sized and oriented microfabricated surface, which is used with a reciprocating wear tester to conduct an experiment on wear, so as to generate wear particles having specific size and morphology. A large quantity of wear particles could be generated within a shortened time. Separating and filtering procedures are included to produce wear particles having more uniform size, so as to meet the standards of pre-clinical test and satisfy requirements in different clinical tests. The method includes three major steps, namely, producing a microfabricated surface, conducting an experiment on wear, and collecting generated wear particles.
