Phosphorene and other layered pnictogens as a new source of 2D materials for electrochemical sensors

Single-atom catalytic growth of crystals using graphene as a case study

“…Indeed, the need for precision manufacturing at the atomic scale is ever more pertinent as we discover and develop new nanomaterials such as clusters (quantum dots), nanowires with variable properties and, of course, the rapidly developing 2D materials. All of these hold great promise for a number of applications ranging from bio-medicine, energy and electronics [12][13][14] . The need for atom precise control for materials fabrication is epitomized by the need for atom precise structuring of 2D materials for device fabrication.…”

Peptide-Based Sensing, Logic Computing, and Information Security on the Antimonene Platform

“…Two-dimensional (2D) materials represented by graphene have set off an extensive research boom and have been used in biosensing, biomedicine, energy, and catalysis . The unique fluorescence quenching ability of 2D materials (graphene, graphene oxide, MoS 2 , and WS 2 ) makes them possible to construct nanosensing platforms in combination with biomolecules (DNA and peptide). , Antimonene, as an emerging 2D material, has great potential for practical applications in electrochemical or surface plasmon resonance (SPR) sensing, biomedicine and energy, due to its optical and electronic properties superior to those of typical 2D materials (like graphene, MoS 2 ). − Moreover, antimonene has strong spin–orbit coupling, tremendous stability, hydrophilicity, and better biomolecule (DNA) sensing sensitivity, which are significantly better than those of graphene. , For example, because of its stronger interaction with single-stranded nucleic acids (ssDNAs or ssRNAs), antimonene can be combined with nucleic acids to develop the sensing systems for electrochemical and SPR detection of microRNA and DNA . However, the interaction between peptide and antimonene and its application in optical sensing, information processing, and security remain elusive.…”

Antimony Nanomaterials Modified Screen-Printed Electrodes for the Voltammetric Determination of Metal Ions

“…In this context, both bismuth and antimony may be developed in a 2D layer structure, typically in a rhombohedral arrangement [9]. However, although the implementation of bismuthene and antimonene as voltammetric sensors presents a great potential, scarce literature is found on the subject [11]. Our group recently reported an exfoliated layered bismuth (2D Bi) based screen-printed electrode (SPE) for the stripping determination of cadmium(II) and lead(II), which demonstrated a superior analytical performance than typical bismuth-based electrodes by providing limits of detection as low as 0.06 and 0.07 μg L − 1 for Pb (II) and Cd(II), respectively [12].…”

“…The 2D layered gray, β-phase or rhombohedral arsenic, antimony, and bismuth occur naturally, thus being the most commonly used in research [11]. Similarly, antimony chalcogenides Sb 2 X 3 (X = S, Se, or Te) have also emerged as nontoxic, highly stable, and low-cost layered materials [14,15].…”
