The rapid detection of urine adenosine is of great significance for the screening of tumors and other diseases,but the existing methods have problems such as complex operation and low sensitivity. In this study,a G quadruple tandem labeled aptamer sensor was proposed for the rapid and sensitive detection of adenosine in urine. Firstly,double-stranded nucleic acids containing an adenosine aptamer(Apt) were covalently modified on the electrode surface. Upon the presence of adenosine,it specifically binds to the aptamer,exposing the primer probe(Primer,P). Subsequently,rolling circle amplification(RCA) is initiated using the exposed primer as a template,which rapidly generates single-stranded nucleic acids rich in G-base repetitive sequences. These sequences self-assemble into G4 structures(G4) in the presence of potassium ions,which could immobilize a large amount of methylene blue(MB),thereby enhancing the response current and elevating the detection sensitivity. Electrophoresis,cyclic voltammetry and AC impedance were used to characterize the sensor construction process,and the adenosine detection conditions were optimized. Under the optimal experimental conditions,the linear detection range of the sensor is 1 fmol/L-1 nmol/L,and the detection limit is 0.68 fmol/L. In addition,the sensor exhibits good stability(RSD=5.4%),reproducibility(RSD=4.1%),and selectivity. The recoveries of adenosine in fresh urine samples were 104%-105%,and the RSDs were 1.5%-5.5%. The aptamer biosensor has the characteristics of easy to operate,high sensitivity,good specificity and low cost,which is anticipated to detect adenosine in urine rapidly and sensitively.
