چکیده
They studied how the complex responded to the primary constituents of blood serum: DNA, RNA, proteins and glucose molecules. We found that the sensor was extremely selective towards DNA even in the presence of RNA and proteins. DNA could be detected fluorescently with parts-per-million accuracy. It turns out that only DNA has the ionic strength capable of separating the PNPB dye from the graphene oxide sheets and thus activating its fluorescence, making this non-toxic complex ideal for applications like identifying contaminant DNA in recombinant proteins.

Mechanism studies on the superior optical limiting observed in graphene oxide covalently functionalized with upconversion NaYF₄ :Yb³⁺/Er³⁺ nanoparticles.
The increased utilization of high power laser sources has rendered great challenges for designing effi cient optical limiting (OL) materials to protect human eyes and various delicate optical devices. An ideal optical limiter should greatly attenuate an intense laser beam while exhibiting high transmittance for low-input optical intensity. [ 1 ] Up to now, numerous organic and inorganic materia...
