Interest in cancer biomarker study has reached a high point with optimism that such assays may eventually take the place of more invasive approaches to cancer diagnosis. However, most methods for cancer biomarker detection are complex and time-consuming. In this study, several cancer biomarker proteins (HSP90, AFP, and CEA) were analyzed in vitro using a simple and fast quantum dots-based biosensing method. In less than 20 minutes of total sampling time, the cancer biomarker proteins were detected to distinguish between healthy and tumorigenic levels. The results have potential applications for fast, early-stage cancer diagnosis in a portable platform.
