“…The convoluted XPS spectra for S 2p peaks indicates the presence of FeS (161.55 eV) and CoS (162.73 eV). The reported values for FeS (161.6 ± 0.1 eV) [32] and for CoS (162.6 ± 0.2 eV) [33] are in agreement with binding energies obtained. The peak around 165 eV can be attributed to the presence of sulfur in the form of sulfate.…”

“…The XPS peaks were assigned [24] using the references available on the online NIMS database for XPS spectra. The curve-fitted XPS spectra in Figure 2, identify the presence of GeS 2 [25] and In 2 S 3 [26] along with In 2 O 3 [27] on the surface. Thus, the surface layer of the chalcogenide glass structure consisted of sulfides [28] along with minor presence of In 2 O 3 .…”

The research in electrochemical reduction of CO 2 is shifting towards the discovery of new and novel materials. This study shows a new class of material, that of Ge-SIn chalcogenide glass, to be active for reduction of CO 2 in aqueous solutions. Experiments were conducted with bulk and particle form of the material, yielding different product for each structural form. Faradaic efficiency of upto 15% was observed in bulk form for CO production while formic acid with up to 26.1 % faradaic efficiency was measured in powder form. Chalcogenide studies have focused primarily on the photoelectrochemical reduction however these results provide a strong merit for introducing metal in chalcogenide glass structures for electrochemical reduction of CO 2. The activity for CO 2 reduction and the change in product selectivity reflects that further efforts to improve the glass structures can be undertaken in order to increase the faradaic efficiency and selectivity of the products.

“…For the ITO surface coated with BSA, the peak area decreases to 1.68% and the SiO 2 peak is not present in the spectra of the ITO surface coated with antibody-spiked BSA. In the 2p detailed scan for sulfur, the peak at 162.4 eV corresponds to the thiol bond to metals [43]. The peaks observed at 163.3 and 163.5 eV are assigned to thiol bonds that are not bound to metals.…”

Catalysis on Nanostructured Indium Tin Oxide Surface for Fast and Inexpensive Probing of Antibodies during Pandemics

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global threat to human health and the economy. Society needs inexpensive, fast, and accurate quantitative diagnostic tools. Here, we report a new approach using a solid-state biosensor to measure antibodies, which does not require functionalization, unlike conventional biosensors. A nanostructured semiconductor surface with catalytic properties was used as a transducer for rapid immobilization and measurement of the antibody. The transducer response was based on solid-state electronics properties. The changes on the surface of the semiconductor induced changes in the direct current (DC) surface resistivity. This was a result of a catalytic chemical reaction on that surface. This new low-cost approach reduced the response time of the measurement significantly, and it required only a very small amount of sample on the microliter scale.
