AbstractThe development of two-dimensional (2D) monoelemental nanomaterials (Xenes) for biomedical applications has generated intensive interest over these years. In this paper, the biomedical applications using Xene-based 2D nanomaterials formed by group VA (e.g., BP, As, Sb, Bi) and VIA (e.g., Se, Te) are elaborated. These 2D Xene-based theranostic nanoplatforms confer some advantages over conventional nanoparticle-based systems, including better photothermal conversion, excellent electrical conductivity, and large surface area. Their versatile and remarkable features allow their implementation for bioimaging and theranostic purposes. This concise review is focused on the current developments in 2D Xenes formed by Group VA and VIA, covering the synthetic methods and various biomedical applications. Lastly, the challenges and future perspectives of 2D Xenes are provided to help us better exploit their excellent performance and use them in practice.

More recently, 2-D graphene oxide (GO)/reduced graphene (rGO) have altered the direction of modern science with material chemistry and physics by research as they offer different key advantages. These are (i) atomically thin 2-D nanosheets (NSs) provide a large surface area (ii) presence of maximum chemically reactive sites, and (iii) higher mechanical strength and flexibility. Considering the progresses of graphene research, we broadly and crucially discuss the formation of the growing family of 2-D GO/rGO in this review paper. Synthesis methodologies are compared, focusing to offer signs for emerging novel and adaptable synthetic methods. Their advantage use in the fields of supercapacitor are highlighted in this review.

An experimental technique is presented for fabricating large surface area semitransparent monocrystalline Si solar cells. The semitransparency is achieved by laser-cutting two-dimensional periodic lattices of ellipses through industrially manufactured Si cells. A novel two-level metal base was invented for minimizing cell breakages during laser cutting. The periodic lattices consist of a large number of ellipses, so as to achieve uniform distribution of the transmitted solar radiation. High efficiencies over 13% are deduced from the I–V curves, recorded under physical sunlight, for all fabricated cells with a 5% transparency.
