Nanosilver of 10-nm size was prepared by the NaBH4–sodium citrate procedure, and it was modified by a single-strand DNA (ssDNA) aptamer to fabricate an AgssDNA probe for melamine. The probe was stabile at pH 7.0 Na2HPO4–NaH2PO4 buffer solutions and in the presence of 25.0 mmol/L NaCl. Upon the addition of melamine, it interacted with the probe to aggregate big clusters, which led to the resonance...
The 5nm nanosilver was prepared by the sodium borohydride procedure, using sodium citrate as a stabilizing reagent. The nanosilver particle was combined with the aptamer for K + to form aptamer–nanosilver complex that was stabile in pH 7.0 Na 2 HPO 4 –NaH 2 PO 4 buffer solutions and in the presence of high concentration of NaCl. In 85°C water bath, K + ...
