“…Reducing the carbonic footprint, the scientific interest is increased in two-dimensional (2D) materials hosting intriguing properties and features beyond graphene [1], featuring many families including transition metal dichalogenides [2], transition metal carbides and carbonitrides under the family of MXenes [3,4], emerging Xene-based 2D members [5][6][7][8][9], to the youngest member in family of transition metal borides as MBenes [10][11][12]. Attributed to the quantum effects, such distinct 2D materials shows intriguing properties like high near-IR absorption, high surface area, nano-thin width, indirect to direct transitions and fascinating science [13,14].…”

Borophene gathered large interest owing to its polymorphism and intriguing properties such as Dirac point, inherent metallicity, etc. but oxidation limits its capabilities. Hydrogenated borophene was recently synthesized experimentally to harness its applications. Motivated by experimental work, in this paper, using ﬁrst-principles calculations and Boltzmann transport theory, we study the freestanding β12 borophene nanosheet doped and functionalized with hydrogen (H), lithium (Li), beryllium (Be), and carbon (C) atoms at different β12 lattice sites. Amongst all possible conﬁgurations, we screen two stable candidates, pristine and hydrogenated β12 borophene nanosheets. Both nanosheets possess dynamic and mechanical stability while the hydrogenated sheet has different anisotropic metallicity compared to pristine sheet leading to enhancement in brittle behaviour. Electronic structure calculations reveal that both nanosheets host dirac cones, while hydrogenation leads to shift and enhancement in tilt of the dirac cones. Further hydrogenation leads to the appearance of additional fermi pockets in the fermi surface. Transport calculations reveals that the lattice thermal conductivity changes from 12.51 to 0.22 Wm-1K-1 (along armchair direction) and from 4.42 to 0.07 Wm-1K-1 (along zigzag direction) upon hydrogenation at room temperature (300 K), demonstrating a large reduction by two orders of magnitude. Such reduction is mainly attributed to decreased phonon mean free path and relaxation time alongwith the enhanced phonon scattering rates stemming from high frequency phonon ﬂat modes in hydrogenated nanosheet. Comparatively larger weighted phase space leads to increased anharmonic scattering in hydrogenated nanosheet contributing to ultra-low lattice thermal conductivity. Consequently, hydrogenated β12 nanosheet exhibits a comparatively higher thermoelectric ﬁgure of merit (∼0.75) at room temperature along armchair direction. Our study demonstrates the effects of functionalization on transport properties of freestanding β12 borophene nanosheets which can be utilized to enhance the thermoelectric performance in two-dimensional systems and expand the applications of boron-based two-dimensional materials.

“…[3][4][5] Numerous 2D nanomaterials have been employed in biomedicine, such as graphene, transition metal dichalcogenides (TMDs), transition metal carbides, nitrides and carbonitrides (MXenes), monoelemental nanosheets like black phosphorus (BP) and graphdiyne, layer like double hydroxides (LDHs), 2D metal-organic frameworks (MOFs), etc. [6][7][8][9][10][11][12][13][14][15][16] Among them, metal-containing 2D materials have become a research frontier in nano-medicine, benefiting from their strong near-infrared (NIR) light absorption, ultrasonic responsiveness and the capacity to produce reactive oxygen species (ROS). [17][18][19][20] Currently, there are mainly two types of metal-containing 2D materials, depending on whether metal species are decorated on the surface of 2D materials or take up the skeleton structures.…”

In recent years, metal-containing two-dimensional (2D) nanomaterials, among various 2D nanomaterials have attracted widespread attention because of their unique physical and chemical properties, especially in the fields of biomedical applications. Firstly, the review provides a brief introduction to two types of metal-containing 2D nanomaterials, based on whether metal species take up the major skeleton of the 2D nanomaterials. After this, the synthetical approaches are summarized, focusing on two strategies similar to other 2D nanomaterials, top-down and bottom-up methods. Then, the performance and evaluation of these 2D nanomaterials when applied to cancer therapy are discussed in detail. The specificity of metal-containing 2D nanomaterials in physics and optics makes them capable of killing cancer cells in a variety of ways, such as photodynamic therapy, photothermal therapy, sonodynamic therapy, chemodynamic therapy and so on. Besides, the integrated platform of diagnosis and treatment and the clinical translatability through metal-containing 2D nanomaterials is also introduced in this review. In the summary and perspective section, advanced rational design, challenges and promising clinical contributions to cancer therapy of these emerging metal-containing 2D nanomaterials are discussed.

Artificial intelligence (AI) has recently emerged as a unique developmental influence that is playing an important role in the development of medicine. The AI medium is showing the potential in unprecedented advancements in truth and efficiency. The intersection of AI has the potential to revolutionize drug discovery. However, AI also has limitations and experts should be aware of these data access and ethical issues. The use of AI techniques for drug discovery applications has increased considerably over the past few years, including combinatorial QSAR and QSPR, virtual screening, and denovo drug design. The purpose of this survey is to give a general overview of drug discovery based on artificial intelligence, and associated applications. We also highlighted the gaps present in the traditional method for drug designing. In addition, potential strategies and approaches to overcome current challenges are discussed to address the constraints of AI within this field. We hope that this survey plays a comprehensive role in understanding the potential of AI in drug discovery.
