Mesoporous silica materials (MSM) have a great surface area and a high pore volume, meaning that they consequently have a large loading capacity, and have been demonstrated to be unique candidates for the treatment of different pathologies, including bacterial infection. In this text, we review the multiple ways of action in which MSM can be used to fight bacterial infection, including early detection, drug release, targeting bacteria or biofilm, antifouling surfaces, and adjuvant capacity. This review focus mainly on those that act as a drug delivery system, and therefore that have an essential characteristic, which is their great loading capacity. Since MSM have advantages in all stages of combatting bacterial infection; its prevention, detection and finally in its treatment, we can venture to talk about them as the “nightmare of bacteria”.

Gold nanoparticles (AuNPs) are extremely promising objects for solving a wide range of biomedical problems. The gold nanoparticles production by biological method (“green synthesis”) is eco-friendly and allows minimization of the amount of harmful chemical and toxic byproducts. This review is devoted to the AuNPs biosynthesis peculiarities using various living organisms (bacteria, fungi, algae, and plants). The participation of various biomolecules in the AuNPs synthesis and the influence of size, shapes, and capping agents on the functionalities are described. The proposed action mechanisms on target cells are highlighted. The biological activities of “green” AuNPs (antimicrobial, anticancer, antiviral, etc.) and the possibilities of their further biomedical application are also discussed.

AbstractNanotechnology is a growing area of research. For example, gold nanoparticles have a wide variety of applications, including optical, electronic, and medical; they are also used as catalysts in biosensor applications and can be used for scanning, carrier, heat source, and sensors. Therefore, nanoparticle synthesis is of great importance to the country’s economy and to scientific development. Nanoparticle synthesis involves using chemical methods, physical methods, or both chemical and physical methods. The synthesis is performed at high pressures or high temperatures and severe conditions, both of which have a high cost in terms of energy. In our investigation, we used a green synthesis method, which used quail eggs that required more moderate conditions and less energy. The yolk from quail eggs has a high protein and vitamin content. Using quail egg yolks, the reaction conditions were optimized in terms of pH, temperature, and concentration. The morphological properties of the obtained gold nanoparticles were characterized using an ultraviolet-visible spectrophotometer, a scanning electron microscope, and an X-ray diffraction analysis.

The field of nanotechnology is advancing rapidly due to its extensive applications in distinct fields of science and technology. Several methods have been used for the production of nanoparticles due to their immense functions in various fields. The limitations of the traditional methods and their toxic nature of the chemicals used during the synthesis or in their application hinder their usage in the biomedical field. This led to the development of the green synthesis of nanoparticles. Researchers have focused on developing simple, cost-effective, clean, non-toxic and eco-friendly procedures for synthesis of nanoparticles. Various biological agents like bacteria, fungi, plant extracts, etc. are used for the green synthesis of metal nanoparticles due to their biocompatibility. The dissolved metals ions are reduced into nano-metals by bio-agent in the green process. The manners and protocols of the green synthesis of gold nanoparticles are presented in this review. Recent literature on green synthesis of noble gold nanoparticles with their various applications in biomedical, antifungal/antibacterial, drug delivery, sensors and photocatalytic have also been discussed.

Due to its excellent characteristics, zeolitic imidazole framework-L (ZIF-L) is widely used in various applications, such as drug delivery, wastewater treatments and energy storage. In the synthesis of ZIF-L, the molar ratio of ligand to metal, the reaction time and the temperature are essential parameters to produce excellent ZIF-L. In this work, ZIF-L was synthesized using a facile and green synthesis method. It was statistically investigated and optimized to obtain the best operating conditions. The optimization was carried out toward the amount of adsorbed crystal violet (CV) dye (q) as the response in the statistics. The optimal ZIF-L was obtained using a molar ratio of ligand to metal of 8.2220 for 97 min at 29 °C, where the q value of the CV adsorption onto this optimal ZIF-L reached 823.02 mg/g. The obtained ZIF-L was characterized using SEM, XRD, FTIR and TGA analyses to ensure its excellent characteristics.
