To Do

  • Repeat Silica-Coating procedure using water to dilute nanoparticles instead of PBS. PBS is likely the cause of the aggregation we have been observing.[1]
  • Repeat ThT-DNA fluorescence procedure to show that fluorescence increases with increasing number of G-quadruplexes formed.

Silica-Coating Part 1

1) Dilute 23.5nM AuNPs to 9.4nM (2mL AuNPs in 3mL water *NOTE: the water was left to assimilate to room temperature prior to dilution*)

2)

ThT/DNA attachment

1) Prepare 100uL of the following concentrations of 4-strand and 8-strand telomeric DNA (which should generate 1 and 2 G-quadruplexes respectively)

a) 100nM

b) 300nM

c) 500nM

d) 700nM

e) 900nM

      • Original Concentrations of 4 and 8-repeats are 265.6uM and 142.8uM, respectively***

4-repeat

1uM(1mL)=(265.6uM)x

x = 3.77uL in 996.23uL

900nM--> 90uL 1uM in 10uL PBS

700nM--> 70uL in 30uL

500nM--> 50uL in 50uL

300nM--> 30uL in 70uL

100nM--> 10uL in 90uL
