Patent ID: 8354222

Claim:
A method for detecting cancer, comprising: providing a biomedical sample suspected of being cancerous; performing a first adsorption step comprising immersing the biomedical sample into a first detection reagent comprising a first adsorbent that adsorbs onto the biomedical sample, wherein a concentration of the first adsorbent is between 5% to 10% w/w and the first adsorbent comprises a long-chain ester containing 16-46 carbon atoms or a long-chain alkane containing 21-30 carbon atoms; performing a first desorption step comprising immersing the biomedical sample into a first desorption reagent for a first period of time; performing a first discrimination step comprising measuring an amount of residual of first adsorbent adsorbed onto the biomedical sample in comparison to an amount of residual of first adsorbent adsorbed onto a normal biomedical sample or a cancerous biomedical sample to determine if cancer cells are distributed within the biomedical sample being tested; performing a second adsorption step comprising immersing the biomedical sample into a second detection reagent comprising a second adsorbent that adsorbs onto the biomedical sample; performing a second desorption step comprising immersing the biomedical sample into a second desorption reagent for a second period of time; and performing a second discrimination step comprising measuring an amount of residual of second adsorbent adsorbed onto the biomedical sample to determine if the cancer cells are distributed within the biomedical sample being tested; wherein the second adsorbent comprises a long-chain alkane containing 21-30 carbon atoms.
