Synthesis of dna-ag2sqds DNA modified silver sulfide Ag2S quantum dots

DNA-Ag2SQDs Deoxyribonucleic acid DNA Modified silver sulfide Ag2S Synthesis of quantum dots

DNA Its chemical composition includes phosphoric acid (P)、 Deoxyribose (S) And four nitrogenous bases : Adenine deoxynucleotides (dAmp)、 Guanine deoxynucleotides (dGmp)、 Cytosine deoxynucleotides (dCmp)、 Thymine deoxynucleotides (dTmp).DNA Its molecular structure is two parallel but opposite polymerized long chains of nucleoside backacid , It rotates relatively around a central axis into a double helix .

DNA（ Deoxyribonucleic acid ） The complex structure of molecules has three important characteristics :

1. People are different ;
2. Life is the same ;
3. Cells in different parts of the same human body DNA Structure is the same .
