Abstract
This paper describes a reduced graphene oxide (RGO)-based resonance light-scattering (RLS) method for thrombin detection by using double strand DNA (dsDNA) as a binding element. dsDNA is obtained by hybridizing DNA1 and DNA2, which respectively consist of one aptamer of thrombin and the complementary strand of the other aptamer of thrombin. When thrombin is added, the specific binding of two aptamers to thrombin results in a complex (DNA1-thrombin-DNA2) and triggers the release of the complementary strand of two aptamers from dsDNA. The released ssDNA can be self-assembled on the surface of RGO to form a stable DNA1-thrombin-DNA2-RGO complex, which increases RLS signals. This simple and rapid method has enabled the detection of thrombin in the picomolar level in buffer and human serum samples. This study is the first to use RGO as a platform in RLS sensor, which can extend the application of RGO.

Abstract
A MoS2-based electrochemical aptasensor has been developed for the simultaneous detection of thrombin and adenosine triphosphate (ATP) based on gold nanoparticles-decorated MoS2 (AuNPs-MoS2) nanocomposites. Two different aptamer probes labeled with redox tags were simultaneously immobilized on an AuNPs-MoS2 film modified electrode via Au-S bonds. The aptamers presented structural switches with the addition of target molecules (thrombin and ATP), resulting in methylene blue (MB) far from or ferrocene (Fc) close to the electrode surface. Therefore, a dual signaling detection strategy was developed, which featured both "signal-on" and "signal-off" elements in the detection system because of the target-induced structure switching. This proposed aptasensor could simultaneously determine ATP and thrombin as low as 0.74 nM ATP and 0.0012 nM thrombin with high selectivity, respectively. In addition, thrombin and ATP could act as inputs to activate an AND logic gate.
