## 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

2uM(500uL)=(265.6uM)x

x = 3.76uL in 496.24

1800nM--> 90uL 10uL PBS

1400nM--> 70uL in 30uL

1000nM--> 50uL in 50uL

60000nM--> 30uL in 70uL

200nM--> 10uL in 90uL

8-repeat

142.8uM(10uL) = (x)(500uL)

x= 2.856

1800nM--> 63uL in 37uL PBS

1400nM--> 49uL in 51uL

1000nM--> 35uL in 65uL

600nM--> 21uL in 79uL

200nM--> 7uL in 93uL
