“…In addition, the industrial applications (e.g. oxide thin films, oxide nanoparticles, oxide nanotubes, and dopant for optical, magnetic, and electronic materials) are increasing remarkably in the last decade, because beryllium and its oxide possess high thermal conductivity, high melting point, high mechanical strength, high insulation nature, and high chemical and thermal stabilities . However, beryllium is unfortunately associated with severe respiratory diseases; thus, the detailed complexation behavior of beryllium ion will be very useful to detect the beryllium in environmental pollution.…”

The complexation behaviors of Be²⁺ with cyclo-μ-imido triphosphate anions, cP₃O₉-n(NH)n(3-)n= 1, 2),have been investigated by both ⁹Be and ³¹P NMR techniques at -2.3 °C in order to clarify the coordination structures of the complexes. The spectra showed that cP₃O₉n(NH)n (n = 1, 2) ligands form ML, ML₂, and M₂L complexes with Be²⁺ ions, and the formation of complexes coordinating with nitrogen atoms of the cyclic framework in the ligand molecule has been excluded. These complexation trends are very similar to those of Be²⁺-cP₃O₆(NH)⁻³₃system, which has been reported by us. The peak deconvolution of ⁹BeNMR spectra made these beryllium complexes amenable to stability constant determinations. The stability constants of the complexes increase with an increase in the protonation constants of the ligands as the number of imino groups, which constitute the ligand molecules, is ascended. This increase is primarily attributable to the lower electronegativity of nitrogen atoms than oxygen atoms, which are directly bonded to central phosphorus atoms; moreover, tautomerism equilibrium in the entire of the imidopolyphosphate molecule is also responsible to the higher basicity. ³¹P NMR spectra measured concurrently have verified the formation of the complexes estimated by the ⁹Be NMR measurement. Intrinsic ³¹P NMR chemical shift values of the phosphorus atoms belonging to ligand molecules complexed with Be²⁺ cations have been determined. Not only the protonation constants but also the stability constants of all Be²⁺ complexes increase approximately linearly with an increase in the number of imino groups.

“…However, more enhancement of the microcantilevers' surface properties is possible. In addition to the above, a Be 2+ optode optical sensor was crafted by Beiraghi A et al In this, the membrane was prepared by adding 1,8-dihydroxy anthrone and sodium tetraphenyl borate (NaTPB) to a plasticized poly-vinyl chloride membrane using ortho-nitrophenyl octyl ether (o-NPOE) as a plasticizer (Beiraghi et al, 2011). When exposed to Be 2+ ions at pH 10.5, the detecting membrane's color changed rapidly from orange to red.…”

Studies at the molecular, systemic, and epidemiological levels have shown that chronic metal exposure is linked to significant health consequences, including cancer, affecting hundreds of millions worldwide. Subtle and convoluted mechanisms underline metals' toxicity and carcinogenicity. The use of sensors for carcinogenic metals' trace detection is on the rise due to their selectivity, simplicity, and affordability. Biotechnology and microelectronics in the development of sensors have grown complementarily in recent years. This study offers a comprehensive overview of current research and advancements in developing sensors for detecting carcinogenic metals. Here, we have focussed on the developed biosensor platforms for group 1 carcinogens, i.e., arsenic, nickel, cadmium, chromium, and beryllium, along with their brief roles in human carcinogenesis. This review also looks at the importance of sensing such metal exposure in humans from a larger perspective, hoping to influence future research toward early prevention and treatment of illnesses like cancer.
