How does Neutral red assay enters a cell?
Viable cells will take up the dye by active transport and incorporate the dye into lysosomes, whereas non-viable cells will not take up the dye. After the cells have been allowed to incorporate the dye they are briefly washed or fixed. The incorporated dye is then liberated from the cells in an acidified ethanol solution. An increase or decrease in the number of cells or their physiological state results in a concomitant change in the amount of dye incorporated by the cells in the culture. This indicates the degree of cytotoxicity caused by the test material.
Asked in Nanotechnology
How can nanotechnology help detect diseases?
Nanotechnology can use to develop bio indicators a type of molecules which will attached to infected cells, they also can be detected from scanning. let say nanotechnology can be used to develop a dye to indicate cancer cells and when a patient given that, the dye molecules will selectively attached to the cancer cells and the dye concentration will increase around the cancer. And once the scanning is done dye can be identified hence the cancer.
