“…Principal component analysis (PCA) is often used for dimensionality reduction of high dimensional variables. Our previous studies suggested that PCA analysis of electrochemical voltammetric data does not have a high interpretative capability . However, as shown in Figure , the three factors extracted within the voltammetric data can reach nearly 90% interpretative capability, suggesting there were significant differences in electrochemical profiles among the plant species studied in this work.…”

Electrochemical profiles of Pueraria bouffordii, P. montana var. lobata, P. montana var. montana, P. montana var. thomsonii, Haymondia wallichii, Teyleria stricta and Toxicopueraria yunnanensis were recorded from leaf tissue after different solvent extractions. The voltammetric data recorded after different solvent extractions can be derived as patterns for species identification. The electrochemical behavior of plant tissue contains its electrochemical active compounds profile. As the distribution of chemical compounds in plants is controlled by genes, these profiles can reflect differences at the genetic level between species. The dendrogram deduced from the electrochemical profile has been used for polyphyly analysis. The result suggests the Teyleria stricta showed very distant relationships with other species. P. montana var. lobata, P. montana var. montana and P. montana var. thomsonii showed a close relationship because they were varietas. Interestingly, H. wallichii showed a close infrageneric relationship within these species, which disagrees with other morphological studies. In addition, the result also provides insight into phylogenetic status of the regionally Toxicopueraria yunnanensis.

“…Our previous studies suggested that PCA analysis of electrochemical voltammetric data does not have a high interpretative capability. [23][24][25][26] Figure 5 shows the PCA result using the electrochemical profiles for all samples. In this case, three factors extracted within the electrochemical profiles can reach 95.2% interpretative capability, indicating that the electrochemical profile between the variety showed significant differences.…”

Electrochemical Profile Recording for Pueraria Variety Identification

The rapid identification of plant variety is valuable in both academic studies and crop production. However, rapid and accurate identification has been difficult because many varieties have very similar morphological characteristics and are susceptible to the effects of the growing environment. In this work, we established an electrochemical method for recording the electro-active profile of compounds in plant tissue. Because the chemical composition of different varieties is largely controlled by their genes, rather than a growing environment, this method has considerable potential for variety identification. Three varieties of Pueraria with sixteen locations were collected for confirming the feasibility of the proposed methodology. Principal component analysis and peak ratio analysis have been used for grouping the sample data. The results indicate the electrochemical profiles of three varieties can be distinguished using their voltammetric data.

“…However, these methods need to be multiplexed. Immunoassay, a common strategy for the quantitative detection of tumor markers, especially in cases of clinical laboratory use [22], remains significantly applicable to fields including biochemical [23,24,25,26,27] and environmental detection [28]. Unfortunately, the traditional methods suffer from having some inner drawbacks, including a lack of precision, requiring a prolonged period of time, and having difficulty in realizing automation.…”

High Sensitive Immunoelectrochemical Measurement of Lung Cancer Tumor Marker ProGRP Based on TiO2-Au Nanocomposite

Progastrin-releasing peptide (ProGRP), which is known to be highly specific and sensitive to small cell lung cancer (SCLC), has been proven to be a valuable substitute for neuron-specific enolase in SCLC diagnostics and monitoring, especially in its early stages. The detection of ProGRP levels also facilitates a selection of therapeutic treatments. For the fabrication of our proposed biosensor, titanium (IV) oxide microparticles were first used, followed by dispersing gold nanoparticles into chitosan and immobilizing them onto a carbon paste electrode (CPE) surface. The developed immunosensor exhibits a much higher biosensing performance in comparison with current methods, when it comes to the detection of ProGRP. Therefore, the proposed CPE/TiO2/(CS+AuNPs)/anti-ProGRP/BSA/ProGRP is excellent for the development of a compact diagnostics apparatus.
