Furthermore, the fluorescence probe also showed the satisfactory results in the determination of Hg(II) in human serum. Subsequently, take advantage of the uric acid (UA) to recover the fluorescence of the Si/N-CDs-Hg(II) complex probe, another enzyme-free ways to determine UA was developed. The complex probe can selectively detect the UA content in the 0.5-30 μM range, and its detection limit can reach 0.14 μM, which has successfully detected the UA in total serum, and the results were no significant difference comparing with the controls.

The hull remains are of a large ship that was unable to enter the shallow anchorage. Among the finds were 20 ceramic items, including bowls, cooking–pots, jugs, a juglet, lids and amphoras. The cargo has not yet been found. Pottery typology, coins and 14C tests of organic material date the shipwreck to between the second half of the 6th and the first quarter of the 7th centuries CE. The construction tradition is different from contemporary shipwrecks from Dor. Petrography and chemical composition analyses of the ceramics indicate an eastern Mediterranean origin.
