*Oligo D samples were run for 300s, the 60pM and 80pM samples are still inconsistent with the trend of the other concentrations | |||
*The first round of MB/DNA samples were run for 300s, results had lots of noise and inconsistencies | |||
*The second round of MB/DNA samples were run for 700s to eliminate noise, only the 25pM sample lied outside the trend of the other concentrations | |||
*Future work: | |||
**Always align laser with 10000x diluted green fluorescent beads, include spectra for comparison | |||
**Create more samples for MB/DNA with 100pM intervals from 1nM to 100pM, and a 75pM sample | |||
**Create more samples for Oligo D at 50, 30, and 10pM concentrations | |||
**Make samples by serial dilutions after hybridization (?) | |||
**For pM concentrations increase time to 700s to eliminate noise from spectra | |||
***Increase time even further for concentrations lower than 25pM (?) | |||
**Attach AuNPs in proper ratio at successfully run concentrations of MB/DNA | |||
