Abstract
AbstractIn the present study, a simple molecular imprinting technique for the quantitative measurement of lysophosphatidic acid (LPA) is reported for the first time through colorimetry. LPA is a phospholipid bioactive involved in many physiological and pathological processes like stimulating DNA synthesis, proliferating ovarian cancer and inducing cell migration. It is reported that the concentration of LPA in patients with gynecological cancers like ovarian cancer is considerably higher than in the control. The early diagnosis of ovarian cancer may exceed the survival rate of patients. There is a need for an analytical tool for point of care detection of ovarian cancer at an early stage. Herein, molecular imprinting technique is used to develop an imprinted β‐Cyclodextrin (β‐CD) polymer using LPA as a template. This MIP prepared was imprinted with an LPA cavity, which has been extended for colorimetry assay. The colorimetric LPA assay was conducted in the spiked blood serum sample. The detection limit of LPA in spiked serum samples is calculated as 0.078 μmol/L.
