A rapid fluorometric method is described for the determination of lactate and cholesterol by using ZnO nanowires (ZnO NWs). The assay is based on the detection of the hydrogen peroxide generated during the enzymatic reactions of the oxidation of lact

The authors describe an aptasensor for the detection of the gonadal hormone progesterone (P4) in aqueous solution. Gold nanoparticles (AuNPs) were coated with a P4-specific aptamer, and such particles do not aggregate in presence of NaCl due to the p

Using rolling circle amplification (RCA) and two different ways of signal readout, we developed analytical methods to detect the receptor-binding domain (RBD) of SARS-CoV-2 spike protein (S protein). We modified streptavidin-coated magnetic beads wit

Molybdenum disulfide (MoS2) surface functionalization was performed with a catechol-containing polymer sodium alginate (SA) and dopamine (DA) through simultaneous MoS2 exfoliation and self-polymerization of DA. The MoS2/SA-PDA nanocomposite was chara

A short ssDNA (Apt-21) rationally truncated from the parent 100 nt As(III) aptamer was used for colorimetric determination of As(III). Apt-21 serves dual functions, i.e., recognition of trace As(III) and regulation of AuNPs dispersion by surface atta

A chloramphenicol (CAP)-binding aptamer of 80 nucleotides (nt) was reported in 2011. In 2014, it was truncated to 40 nt and has since been used by most researchers, although a careful binding study is still lacking. In this work, binding assays using

As a first of its kind, we developed a highly sensitive colorimetric nanoprobe for phytic acid (PA) and Fe(III) ion detection based on 4-mercaptophenol (4MP) and thioglycolic acid (TGA)-functionalized gold nanoparticles {AuNPs@(4MP-TGA)}. AuNPs were
