Fluorescent Silica Beads for Detection of Cervical Cancer

摘要

We present the use of self-assembled fluorescent silica (glass) beads for detection of cervical cancer. The cells from three different individuals (3 normal and 3 tumor) were tested for affinity by using the beads, a few microns glass nanoporous particles which contain florescent dyes sealed inside the pores. We have developed two different methods for detecting the affinity in a Petri-dish. After simple precipitation of the beads onto the cells, the unbounded beads removed by washing. The next method involved using centrifugation for the removal of the unbounded beads. Both methods show unambiguous identification between the normal and tumor cells.
