“…Eqn ( 6) is the dissolution-precipitation equilibrium for Cu(OH) 2 , and eqn (7) and ( 8) are the dissolution-precipitation equilibrium for CuS. Eqn (8) is the combination between eqn ( 7) and (4). Further, the combi-nation of dissolution-precipitation equilibrium eqn (6) for Cu (OH) 2 and 7 for CuS produces the precipitation transformation reaction (9).…”

“…[2][3][4] Precipitation and coprecipitation methods, which are based on the K sp theory, are widely applied for material preparation or ionic removal in fields of energy, environment, health, catalysis, sensing, and so on. [5][6][7][8][9][10] Furthermore, the K sp gap between two ionic compounds sharing the same cation or anion can trigger precipitation transformation reactions, which widely exist in nature and daily life. For instance, the deeper ores of sphalerite (ZnS, K sp = 1.6 × 10 −24 ) and galena (PbS, K sp = 8.0 × 10 −28 ) can be converted to covellite (CuS, K sp = 6.3 × 10 −36 ) after being infiltrated by CuSO 4 solution, which are formed by the oxidation and eluviation of the shallower primary copper sulfide ore.…”

Background Heavy metal pollution has become a major source of environmental pollution because of increasing industrialization. Microbial remediation is a promising approach to remediate lead-contaminated environments owing to its cost-effective, environment-friendly, ecologically sustainable, and highly efficient properties. In this study, the growth-promoting functions and lead-adsorption ability of Bacillus cereus SEM-15 were examined, and the functional mechanism of the strain was preliminarily identified using scanning electron microscopy, energy spectrum, infrared spectrum, and genome analyses, providing theoretical support for utilization of B. cereus SEM-15 in heavy metals remediation. Results B. cereus SEM-15 showed strong ability to dissolve inorganic phosphorus and secrete indole-3-acetic acid. The lead adsorption efficiency of the strain at lead ion concentration of 150 mg/L was more than 93%. Single factor analysis revealed the optimal conditions for heavy metal adsorption by B. cereus SEM-15 (adsorption time, initial lead ion concentration, pH, and inoculum amount were 10 min, 50–150 mg/L, 6–7, and 5 g/L, respectively) in nutrient-free environment, with the lead adsorption rate reaching 96.58%. Scanning electron microscopy of B. cereus SEM-15 cells before and after lead adsorption showed adherence of a large number of granular precipitates to the cell surface after lead adsorption. X-Ray photoelectron spectroscopy and Fourier transform infrared spectroscopy results indicated the characteristic peaks of Pb–O, Pb–O-R (R = functional group), and Pb–S bonds after lead adsorption, and a shift in the characteristic peaks of bonds and groups related to C, N, and O. Genome annotation results showed the presence of genes related to heavy metals tolerance and plant growth promotion in B. cereus SEM-15, providing a molecular basis for the strain’s heavy metals tolerance and plant growth promotion functions. Conclusions This study analyzed the lead adsorption characteristics of B. cereus SEM-15 and the associated influencing factors, and discussed the adsorption mechanism and related functional genes, providing a basis for clarifying the underlying molecular mechanism and offering a reference for further research on plant-microorganisms combined remediation of heavy metals polluted environments.

Biosensors-on-chip (BoC), compact and affordable public diagnostic devices, are vital for preventing health crises caused by viral and bacterial mutations, climate change, and poor diets. Clinical, remote, and field use are possible with these devices. BoC is used in food safety, environmental monitoring, and medical diagnosis. The coupling of tunneling magnetoresistance (TMR) sensing elements in chip form with surface functionalized green synthesized iron oxide nanoparticles (GS-IONPs) as a biomarker, known as TMR/GS-IONPs, allows BoC devices to be made. The functional framework of BoC based on TMR/GS-IONPs, the instrument system, and biomolecule immobilization are covered in this review. This review aims to overview the recent research on a biosensor using TMR technology with IONPs biomarkers and discusses its future advances in point-of-care diagnostics. TMR sensor has revolutionized low-magnetic field sensing technologies, yet biosensing faces challenges. Large magnetization of IONPs to generate sufficient stray-field to disturb its magnetic moment, compact and inexpensive instrumentation to sense the low voltage yielded by the TMR/GS-IONPs system, and high-selectivity bio-analyte immobilization to the surface of IONPs to increase sensor sensitivity are the notable issues. Additionally, improving device performance requires creating high-TMR materials. Despite challenges, research and technological advances hold great promise for TMR/GS-IONP bioapplications.
