我们提出了DNA稳定的银纳米团簇（Ag-N-DNAs）与近红外（NIR）发射的生物组织透明窗口的化学合成策略。升高的温度可以显著增加近红外纳米团簇的化学产率。在大多数情况下，碱性pH有利于近红外纳米团簇，而微摩尔量的NaCl抑制它们的形成。
We present chemical synthesis strategies for DNA-stabilized silver nanoclusters (Ag-N-DNAs) with near-infrared (NIR) emission in the biological tissue transparency windows. Elevated temperatures can significantly increase chemical yield of near-infrared nanoclusters. In most cases, basic pH favors near-infrared nanoclusters while micromolar amounts of NaCl inhibit their formation.
