Engineering of efficient functionalization in a zirconium-hydroxyl-based metal–organic framework for an ultra-high adsorption of Pb2+ ions from an aqueous medium: an elucidated uptake mechanism

“…Recently, metal-organic frameworks (MOFs) have attracted numerous studies in the efficient purging of heavy metal ions from wastewater due to their extraordinary properties, such as high specific surface area, versatile structure with high crystallinity, and easy post-synthetic modification. 23,24 To date, MOFs have been reported with potential applications in many fields, including catalysis, [25][26][27][28] separation, 29,30 sensor, 31,32 energy storage, 33,34 and adsorption. [35][36][37][38] Noteworthily, the MOF architecture can be adjusted by functional groups to enhance the interactions between the adsorption sites and guest moieties, driving new promising approaches with respect to adsorption.…”

A surface molecularly imprinted electrochemical biosensor for the detection of SARS-CoV-2 spike protein by using Cu7S4-Au as built-in probe

“…For instance, Ratautaite et al [12] proposed molecularly imprinted polypyrrole, which acted as the MIPs and was successfully used in the detection of SARS-CoV-2 S protein by pulsed amperometric detection (PAD). However, conventional bulk imprinting is usually difficult to be applied for protein templates owing to the conformational change of proteins during the bulk imprinting process [14] , [15] . Surface imprinting, in which the templates are attached to the surface before polymerization, is especially suitable for protein templates, because it can minimize the aggregation of the templates and provide more accessible binding sites than bulk imprinting [16] , [17] .…”
