Gold(III)
chloride trihydrate (HAuCl₄·3H₂O), dithiothreitol
(DTT), and triethylamine
(TEA) were purchased from J&K Scientific LTD (Peking, China).
All oligonucleotides (Table S-1) were synthesized
and purified through HPLC by Sangon Biotech Co., Ltd. (Shanghai, China).
NAP-5 columns (Sephadex G-25 Medium, DNA grade) were purchased from
Pharmacia Biotech (GE Healthcare Bio-Sciences, Uppsala, Sweden). ZEN0117-disposable
low volume cuvettes (100 μL) were purchased from Malvern Instruments
Ltd. (Malvern, England). Millipore H₂O purified with a
Millipore ultrapure water system was used throughout the experiments.
The bare AuNPs (13.0 ± 0.4 nm in diameter measured by transmission
electron microscope, Figure S-1) were in-house
prepared following the literature protocols.^{41 (link)} Through the immobilization process, the polydispersity of the DNA/AuNP
conjugates was all in the range from 0.17 to 0.28, indicating their
good quality and narrow distribution for the cumulants analysis.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
