The resulting biosensor exhibits ultrasensitivity towards BPA at low concentration (5 fM) without any labeling, modification, immobilization, or washing procedure.
This U.S.D.A. document lists dozens of chemicals that processors can apply to meat without any labeling requirement.
These results indicate that the 3D ePD image clearly captures morphological changes of PSC colonies during reprogramming and differentiation without any labeling of cells.
On this basis, without any labeling and additional coreactants, an accurate and reliable sensing system based on the dual-potential ECL of NGQDs toward Co2+ ion was fabricated with excellent sensitivity and selectivity against other interferential metal ions.
Another sore point in the public discussion of AquaBounty's salmon has been the possibility that the fish, like all modified crops grown in the country, could be sold on store shelves without any labeling.
Even without any labeling, however, the PD imaging system produces a series of ePD images of a PSC colony along the z-axis, which can be overlaid to reconstruct a 3D image of the colony (Figs 1d and 6a and Supplementary Videos S1, S2).
Furthermore, since the proposed electrochemical virus sensor is designed for direct determination without any labeling structure, the electrochemical communication between redox target and electrode surface will reduce interference reactions and simplifies the detection system with small amount of reagent and better stability.
Utilizing this phenomenon, antigen-antibody reactions at the cells' surfaces have been detected without any labeling onto the antibody molecules in a microchannel [18], [19].
Finally, we performed in vivo SHG imaging of rat corneas and achieved structural imaging of corneal stroma without any labeling.
There is a need for a noninvasive technique to monitor living pluripotent stem cell condition without any labeling.
SPR enables rapid detection in real time without any labeling of samples and can be utilised for concentration determination, kinetics studies and epitope mapping.
