Nanoparticles for detecting calcium ions and method for detecting calcium ions using the same

摘要

The present invention for the nano calcium ion detection particles , their preparation and the detection method of the calcium using the same relates . Nanoparticles for detection of calcium ion of the present invention has got a high selectivity for the calcium ion , even in the presence of other metal ions can be detected only as a calcium ion selective , it has a high sensitivity to calcium ions , very small amount of calcium ion can be detected . In addition , calcium ion detection method of the present invention does not require a step of adding a separate salt , not a constraint for the composite material to stabilize the gold nanoparticles , the human eye simply determine whether the calcium ions present in the sample can . ;
