  • Patent number: 11883536
    Abstract: A method of preparing polylactic acid (PLA) microsphere and polylactic-co-glycolic acid (PLGA) microsphere is provided, including the following steps. A first solution is provided, including polylactic acid or polylactic-co-glycolic acid and an organic solvent. A second solution is provided, including polyvinyl alcohol, sodium carboxymethyl cellulose and an aqueous solution. The first solution is added to the second solution and, at the same time, the second solution is agitated until polylactic acid is solidified to form a plurality of polylactic acid microspheres, or until polylactic-co-glycolic acid is solidified to form a plurality of polylactic-co-glycolic acid microspheres. The polylactic acid microspheres or polylactic-co-glycolic acid microspheres are collected.

  • Publication number: 20210199652
    Abstract: The present disclosure provides a test kit for simultaneously detecting a plurality of analytes, in which the test kit includes a lysis solution and a test strip. The lysis solution includes a salt, a surfactant, a stabilizer, and a buffer solution. The test strip includes a sample pad, a conjugation pad, a cellulose membrane, and a water-absorbing pad sequentially arranged on a support plate. The conjugation pad includes a conjugation pad solution and a plurality of antibody-conjugated microspheres, and the antibody-conjugated microspheres recognize plurality of analytes. The test kit of the present disclosure achieves an effect of simultaneously detecting more than or equal to four analytes even though the conjugation pad has a limited capacity of the antibody by preparing the lysis solution with appropriate ingredients and improving a formulation of the solution contained in the test strip.
