Nanobiosensors in Therapeutic Drug Monitoring
Due to the high bacterial resistance to antibiotics (AB), it has become necessary to adjust the dose aimed at personalized medicine by means of therapeutic drug monitoring (TDM). TDM is a fundamental tool for measuring the concentration of drugs that have a limited or highly toxic dose in different body fluids, such as blood, plasma, serum, and urine, among others. Using different techniques that allow for the pharmacokinetic (PK) and pharmacodynamic (PD) analysis of the drug, TDM can reduce the risks inherent in treatment. Among these techniques, nanotechnology focused on biosensors, which are relevant due to their versatility, sensitivity, specificity, and low cost. They provide results in real time, using an element for biological recognition coupled to a signal transducer.

Applications of Carbon Dots
Although there is significant progress in the research of carbon dots (CDs), some challenges such as difficulty in large-scale synthesis, complicated purification, low quantum yield, ambiguity in structure-property correlation, electronic structures, and photophysics are still major obstacles that hinder the commercial use of CDs. The unique properties of CDs, such as good biocompatibility, high photostability, excellent light-harvesting, up-conversion, effective electron transfer, and bandgap narrowing, make the CDs promising nanomaterials for applications in many fields.

Using CNSL for the Synthesis of Surfactants
Cashew Nut Shell Liquid (CNSL) is a promising non-edible renewable resource, directly extracted from the shell of the cashew nut. The interesting structure of CNSL and its components (cardanol, anacardic acid and cardol) lead to the synthesis of biobased surfactants.

Imidazoline Surfactants
Imidazoline surfactants are a class of surfactants with a hydrophobic tail and an imidazoline hydrophilic head. They are commonly used as emulsifiers, wetting agents, and cleaning agents in a variety of applications, including personal care, industrial cleaning, and agriculture. Imidazoline surfactants are known for their stability in acidic and alkaline conditions, making them a popular choice for many industrial processes. Imidazoline surfactants are mainly the cationic surfactants that contain an imidazoline ring in their chemical structure. They are commonly used as emulsifiers, corrosion inhibitors, and wetting agents in a variety of industrial and household applications. Imidazoline surfactants are typically synthesized by reacting a fatty acid or fatty amine with an imidazole or imidazoline compound. The resulting surfactants have a unique combination of properties, including excellent emulsification, wetting, and corrosion inhibition abilities.

Antimicrobial photodynamic therapy (aPDT)
Photodynamic inactivation is known as a new antimicrobial photodynamic therapy (aPDT). It is based on the administration of a photosensitizer located in the bacterial/viral cell followed by exposure to light radiations (with a proper wavelength corresponding with the maximum value of absorption of the photosensitizer) that generate singlet oxygen or reactive oxygen species, which lead to the death of different microorganisms. This review will present an overview beyond the state-of-the-art of the photosensitizer types (based on tetra-p-sulphonated-phenyl porphyrin—TSPP, which is able to form cationic and J-aggregates forms at different pH values ((1–4) and concentrations around 10−5 M) and their applications of PDT for viruses, especially.

Natural sulfur containing compounds
The present review aims to characterize the general characteristics, physicochemical properties,and health-related studies of onion, garlic, and cruciferous vegetable consumption, as well as theinfluence of food processing on their content of active substances. The review combines distinctchapters where information relevant for nutraceutical and functional food engineers, medical doctors,as well as consumers can be obtained. We believe that the review will stimulate further studies relatedto the implementation of the most accurate sources of sulfur compounds from chosen plants whichcould support the therapy of cancer patients. Moreover, the review aims to present cost-e ectiveanti-tumor means that would include the implementation in the diet of sulfur-based compoundsin foods.

Synthesis of MoS2
Molybdenum disulfide (MoS2), with a two-dimensional (2D) structure, has attracted huge research interest due to its unique electrical, optical, and physicochemical properties. MoS2 has been used as a co-catalyst for the synthesis of novel heterojunction composites with enhanced photocatalytic hydrogen production under solar light irradiation. Nanostructured MoS2 can be fabricated via both top-down and bottom-up approaches.

Magnesia as Alternative Binder
Magnesia, or Magnesium oxide (MgO),  is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium. It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic bonding. Magnesia is mainly produced by the calcination of magnesium carbonate. Calcining at different temperatures produces magnesia of different reactivity. The use of reactive MgO as binder in cementitious materials has its advantages and disadvantages.

LPCS for Metal-Ceramic/Ceramic Coatings
Based on the recent analysis of various databases, cold spray (CS), the newest method among thermal spraying technologies, has received the unabated attention of hundreds of researchers continuously since its invention in the 1980s. The significance of CS lies in the low process temperature, which usually ensures compressive residual stresses and allows for the formation of coatings on a thermally sensitive substrate.
