Copper Nanoclusters for Heavy Metal Ions Detection
Heavy metal ions (HMIs) can accumulate in the human body and cause poisoning. They can enter the biological chain from nature in many ways and are difficult to degrade in the body. HMIs can be detected by colorimetric methods, fluorescence methods, and point-of-care testing (POCT). POCT technology based on smartphone has the advantages of on-site diagnosis and portability. However, the technology relies on a wide variety of accessories that can be affected by environmental changes. Colorimetric methods for color evaluation are an important problem, and another problem is the stability of color. The fluorescence method is widely used in HMIs determination because of its advantages of simple operation, low cost, and high sensitivity. In addition, the fluorescence sensor has the characteristics of strong specificity, fast detection speed, and high accuracy. CuNCs are used as sensors to detect HMIs. The low-cost detection method brings convenience to the actual detection.

Citrus Uses in the Food Industry
Citrus fruits occupy an important position in the context of the fruit trade, considering that both fresh fruits and processed products are produced on a large scale. Citrus fruits are recognized as an essential component of the human diet, thanks to their high content of beneficial nutrients such as vitamins, minerals, terpenes, flavonoids, coumarins and dietary fibers. Among these, a wide range of positive biological activities are attributed to terpenes and flavonoids derivatives.

Nanotechnology with Photo- and Radiotherapy for Colorectal Cancer
Colorectal cancer is the third most common cancer worldwide. Despite recent advances in the treatment of this pathology, which include a personalized approach using radio- and chemotherapies in combination with advanced surgical techniques, it is imperative to enhance the performance of these treatments and decrease their detrimental side effects on patients’ health. Nanomedicine is likely the pathway towards solving this challenge by enhancing both the therapeutic and diagnostic capabilities. In particular, plasmonic nanoparticles show remarkable potential due to their dual therapeutic functionalities as photothermal therapy agents and as radiosensitizers in radiotherapy.

Photocatalytic Degradation of Antibiotics
Various methods, including carbon filtration, ozonation, catalytic membranes, Fenton-like catalysis, sorption, and biodegradation have been employed to eliminate such enduring antibiotic substances. As a result, wastewater accumulates effluents from corporations, clinics, and farmland. Sewage treatment is typically regarded as the preferred method for treating these antibiotics. Photocatalysis has gained a lot of interest as an effective method for eliminating antibiotic contaminants since it is inexpensive, effective, and environmentally benign as it eliminates antibiotics in sunlight and under ambient conditions. The reactions endured by a semiconductor and the potential to absorb photons with energies higher than its energy band gap is called “photocatalytic degradation”.

Agricultural Applications of Superabsorbent Polymer Hydrogels
Although natural polymers, such as various polysaccharides, have undoubted advantages related to their biocompatibility, biodegradability, and low cost, they are inferior to synthetic polymers in terms of water absorption and water retention properties. In this regard, the most promising are semi-synthetic polymeric superabsorbents based on natural polymers modified with additives or grafted chains of synthetic polymers, which can combine the advantages of natural and synthetic polymeric hydrogels without their disadvantages. Such semi-synthetic polymers are of great interest for agricultural applications, especially in dry regions, also because they can be used to create systems for the slow release of nutrients into the soil, which are necessary to increase crop yields using environmentally friendly technologies.

Green Chemistry Principles for Cellulose-Based Hydrogels
Hydrogels are 3D structures consisting of hydrophilic polymer networks. They can adsorb water and biological fluids in high quantities (up to 1000 times their dry weight). Cellulose is a hydrophilic material. It has inter- and intramolecular hydrogen bonds and van der Waals forces that cause many problems regarding its dissolution.

Geopolymer Materials for Bone Tissue Applications
Geopolymers (alkali-activated materials) are amorphous inorganic polymeric systems with aluminosilicate bases produced by alkalinising natural or waste substances, such as metallurgical, industrial, urban, and agricultural wastes. There is increasing academic interest in geopolymer materials for biomedical applications.

Prussian Blue and Its Analogues
Prussian blue analogues (PBAs)-based anode materials (oxides, sulfides, selenides, phosphides, borides, and carbides) have been extensively investigated in the field of energy conversion and storage. This is due to PBAs’ unique properties, including high theoretical specific capacity, environmental friendly, and low cost.

Biomedical Application of Carbon Dots
Carbon dots (CDs), which are a new category of carbon nanoparticles that consist of quasi-spherical, discrete fluorescent carbon nanomaterials with a diameter of less than 10 nm, have multiple advantages over semiconductor quantum dots (QDs), including high water solubility, low cost, excellent biocompatibility, chemically inertness, highly tunable photoluminescence and electrochemical luminescence. Because of their unique properties, carbon quantum dots (CQDs) have acquired significance in nano-chemistry, which has resulted in the discovery of CDD applications, especially in biomedical applications.
