Simeon,N.,Myers,R.,Bayle,C.,Nertz,M.,Stewart,J.K.,Couderc,F.Some applications of near-ultraviolet laser-induced fluorescence detection in nanomolar- and subnanomolar-range high-performance liquid chromatography or micro-high-performance liquid chromatography.Journal of Chromatography A. 2001...
This concept allows for the easy fabrication of the electrode, without the need of any conditioning step and presenting a limit of detection in the nanomolar range (i.e. 5 nM Ag+ concentration). Thus, the preparation of the electrode was accomplished on the basis of commercial glassy ...
The SPR signal had a good linear relationship with thrombin concentration in the range of 0.1-75 nM, and the detection limit for thrombin was determined to be as low as 0.1 nM. It was found that aptamer functionalized AuNPs enhanced the signal of SPR response and thus increased the limit ...
At HPPD was identified to be the first subnanomolar-range At HPPD inhibitor ( K _(i) = 0.86 nM), which significantly outperformed that of the lead compound MBQ ( K _(i) = 8.2 nM). Further determination of the crystal structure of At HPPD in complex with compound 60 (1.85 ?) ...

Under optimum conditions and accumulation time of 60s, linear dynamic range was 0.1–10ng/ml (8.7×1010 to 8.7×108M) with a limit of detection of 0.03ng/ml (2.6×1010M); at accumulation time of 5min, linear dynamic range was 0.04–10ng/ml (3.4×1010 to 8.7×108M) with a limit ...
The electrode exhibits a Nernstian response toward Be(II) ions over a very wide concentration range (1.0 × 10 4 –1.0 × 10 10 M), with a detection limit of 3.5 × 10 11 M (350 pg/L). In fact, the electrode presents a fast response time in the whole concentration range (6 s)...
trifolii are fully capable of eliciting various symbiosis-related responses in white clover in the same concentration range as extracellular CLOSs of other rhizobia on their respective legume hosts. These results and our earlier studies indicate that membrane CLOSs represent one of many different classes...
On the addition of OTA in the concentration range of 0.1鈥 10 nM, the SERS signals appeared to decrease by 40%, since OTA's aptamer could not adsorb onto the surface of AgNPs due to binding with OTA. We verified our results against a control experiment with warfarin, which did not ...
Thanks to the modular design of the antibody library, one anti-ED-B antibody could easily be affinity-matured, yielding a binder with dissociation constant in the picomolar range (Kd = 54 pm). EXPERIMENTAL PROCEDURES Library Construction and Cloning The antibody library was cloned using single VH...
