We found that the ratio of L. casei cell numbers to auric acid concentration was important in terms of nanoparticle synthesis. Excess auric acid inhibited L. casei metabolism, and an excessive number of L. casei cells resulted in the production of large amounts of reducing agents, which may ...
In the samples where HPβCD was added, the mass ratio between Au3 and the added HPβCD was 1:50. Multi-photon bio-imaging tests E. coli and J774A.1 were chosen as the typical cells for bio-imaging tests. J774A.1 cell line was bought from American Type Culture Collection (ATCC). ...
(5 nm, British BioCell International) at the equivalent molar ratio to DNA. Before conjugation with DNA, the AuNS coated with bis(p-sulfonatophenyl)phenylphosphine dihydrate dipotassium (BSPP, 100 ml of AuNS solution mixed with 100 mg BSPP) was purified three times by Microsep ...
The AuNPs provide additional features such as excellent electrical properties, large surface-to-volume ratio, and high surface reaction activity, resulting in a high-performance electrode surface [27]. In this work, we propose a CME for simultaneous detection of HQ, CC, and RS using an ErGO-c...
