The fish (scales and bones), snail shells, bovine bones, horse bones, egg shells, cuttlefish bones and crab shells are composed by crystals of calcium carbonate (94%), organic matter (4%), calcium phosphate (1%) and magnesium carbonate (1%). EDX data for derived HAp from natural sources at 600°C, 800°C, 900°C and 1100 °C, respectively. Based on the EDX signatures, the Ca/P weight ratio for derived HAp was calculated and was found to be 1.67 at 600°C, 800°C, 900°C and 1100 °C, respectively. In the present work, it was found that XRD 2θ positions of the (bones, scales and shells) samples calcined at 600 °C and 1100 °C shifted by total error of 0.056 and 0.031, respectively, thus indicating that the HAp lattice has contracted due to loss of OH radicals. The peak at 1026-1049 cm-1 (ν3) was attributed to triply degenerate asymmetric ν3(PO) stretching. The tetrahedral PO4 3− internal mode (ν1) observed at 960 cm-1 represents the symmetric stretching of the P-O bond. The position of this peak represents the degree of crystallinity of the material and confirmed that the prepared HAp had highly crystallized nature.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49067317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ultrasensitive detection was attained using a specific ssDNA (thiolated aptamer at the 5′ end) as a recognition element. The aptamer was fastened onto GCE/rGO/Au surface via the Au-S bond for determining the impedance of charge mobility by means of [Fe(CN)6] 3-/4as a redox gauge. The function of aptasensor based on the specific interaction between the aptamer and specific surface antigen HBsAg induced [HBsAg-aptamer] complex formation which impeded electron movability between a [Fe(CN)6] 3-/4redox probe solution and sensing interface. HBsAgbinding aptamer events can be easily monitored by the signal switch through cyclic voltammetry technique (CV), square wave voltammetry (SWV), and electrochemical impedance spectroscopy (EIS) measurements. Under the optimized conditions, the aptasensor can detect HBsAg in the 0.25 fg/mL to 1.5 fg/mL concentration range and limit of detection of 0.018, 0.0016 and 0.001 fg/mL for CV, SWV and EIS respectively. The recovery of 88-109.6% was obtained. Moreover, the selectivity of the aptasensor was tested using other biological interfering substances. This developed aptasensor provided one of the lowest limits of detection for HBsAg recently reported in the literature, satisfying stability and good reproducibility, consequently could be applied for revealing HBsAg in real samples.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43522107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
