“…The 2D/2D/1D configuration of GCN/WO 3 /ZnO-NRs facilitated the high adsorption of imidacloprid. The π–π interactions between the aromatic moiety of imidacloprid and GCN as well as coordinate bonding interaction between the metal ions and nitrogen/oxygen containing functional groups of imidacloprid collectively promoted the adsorption process through a pseudo-second-order kinetic model and Freundlich isotherms …”

Heterostructuring the g-C 3 N 4 (GCN) with wide gap oxide photocatalysts is of prominent interest as they can harvest photons spanning the UV−visible region. In this regard, GCN/ZnO have garnered remarkable attention due to their admirable structure, optical, dimensional anisotropy, and electronic properties. The 2D sheet-like structure of GCN can serve as a suitable substrate for the growth of distinct ZnO nanostructures under the multitude of reaction conditions. This review focuses on the progress in the rational design and interface engineering of GCN/ZnO to from Type-II and Z/S-scheme heterojunctions, followed by their relevant photocatalytic applications toward H 2 evolution, CO 2 reduction, pollutant degradation, and bacteria inactivation. The mechanism underlying the crystallization of GCN and ZnO together with their intimate contact in the composite are emphasized under the light of diverse preparation methods. The modification of GCN/ZnO with cocatalysts such as metals, alloy, semiconductors, and carbon materials to form ternary systems to highlight their advancements. The gap analysis and future prospectus of this intricate heterostructure concerning the challenges in synthetic approaches and the charge carrier dynamics are discussed. This review envisages the development of efficient GCN/ZnO-based heterostructures for multiscale applications.

Bladder cancer (BC) is the second most common cancer of the urinary tract in men and the fourth most common cancer in women, and its incidence rises with age. There are many conventional methods for diagnosis and treatment of BC. There are some current biomarkers and clinical tests for the diagnosis and treatment of BC. For example, radiotherapy combined with chemotherapy and surgical, but residual tumor cells mostly cause tumor recurrence. In addition, chemotherapy after transurethral resection causes high side effects, and lack of selectivity, and low sensitivity in sensing. Therefore, it is essential to improve new procedures for the diagnosis and treatment of BC. Nanotechnology has recently sparked an interest in a variety of areas, including medicine, chemistry, physics, and biology. Nanoparticles (NP) have been used in tumor therapies as appropriate tools for enhancing drug delivery efficacy and enabling therapeutic performance. It is noteworthy, nanomaterial could be reduced the limitation of conventional cancer diagnosis and treatments. Since, the major disadvantages of therapeutic drugs are their insolubility in an aqueous solvent, for instance, paclitaxel (PTX) is one of the important therapeutic agents utilized to treating BC, due to its ability to prevent cancer cell growth. However, its major problem is the poor solubility, which has confirmed to be a challenge when improving stable formulations for BC treatment. In order to reduce this challenge, anti-cancer drugs can be loaded into NPs that can improve water solubility. In our review, we state several nanosystem, which can effective and useful for the diagnosis, treatment of BC. We investigate the function of metal NPs, polymeric NPs, liposomes, and exosomes accompanied therapeutic agents for BC Therapy, and then focused on the potential of nanotechnology to improve conventional approaches in sensing.

Herein, cellulose as a natural biomass along with urea was acid-charred to synthesize nitrogen-doped carbon nanoflakes (N-CNF). The as-prepared N-CNF was used to rapidly remove the effluent of agricultural waste containing an Imidacloprid (IMD) insecticide. The adsorption data fit well to nonlinearly in the Sips adsorption model, which is a mixed Langmuir-Freundlich model with an adsorption capacity of ∼104.9 mg g −1 . The adsorption follows pseudo-second-order kinetics linearly and nonlinearly, and thermodynamic parameters reveal that the adsorption process was spontaneous and endothermic. The effect of pH and the interference of ions was also checked. Further, spiking of IMD in different soil, lake, and tap wastewater samples was also done to enhance the practical applicability of removing IMD by N-CNF. The antibacterial properties of N-CNF were checked on both Gram-negative and Gram-positive bacterial strains as Escherichia coli and Bacillus subtilus, respectively, where they showed nontoxic behavior up to the concentration of 2 mg mL −1 .
