“…Los bionanosensores pueden ser clasificados de acuerdo con el tipo de mecanismo de transducción usado para la generación de señales como, electroquímicos, piezoeléctricos y ópticos. Estos últimos poseen la capacidad de detectar variaciones en las propiedades relacionadas con la radiación electromagnética como la longitud de onda, el tiempo de decaimiento, la intensidad de emisión o luz esparcida tanto elástica como inelástica (Raman) y la polarización de la luz (Kneipp et al, 2008;Li et al, 2015;Shao et al, 2010;Sun et al, 2019;Srivastava et al, 2017).

In this work, the optical and electronic properties of nanomaterials are discussed, its fundamental characteristics and its application in the design of devices and techniques for detection, imaging and therapy, especially in cancer problems, are analyzed. Some recent results obtained in our laboratory where we have been able to measure concentrations of the order of 10 -22 moles of complexes of interest are discussed. We report the detection of residues in blood of medications of the order of 10 -8 and 10 -9 molar (M), which opens the way for drug monitoring with a focus on the implementation of a personalized medicine. We discuss results of therapy techniques with the use of nanomaterials that have allowed us to reduce cell viability below 10%. These results show that nanotechnology is changing the health paradigm to preventive medicine, personalized and available to everyone.

“…ENMs are rapidly being used in pharmaceuticals as carriers ( 57 , 58 ) and as nano-formulations of drugs ( 59 – 61 ) and for electro-analysis of pharmaceuticals ( 62 , 63 ). ENMs also find diverse applications in agriculture ( 64 ) to increase the productivity by providing nano-scaled solutions primarily as pesticides ( 65 ), fertilizers ( 65 ), and biosensors ( 66 ). A fraction of these ENMs may also make their way into soil and water ecosystems, and therefore into drinking water and food products ( 67 – 69 ).…”

Role of Endocrine-Disrupting Engineered Nanomaterials in the Pathogenesis of Type 2 Diabetes Mellitus

Nanotechnology has enabled the development of innovative technologies and products for several industrial sectors. Their unique physicochemical and size-dependent properties make the engineered nanomaterials (ENMs) superior for devising solutions for various research and development sectors, which are otherwise unachievable by their bulk forms. However, the remarkable advantages mediated by ENMs and their applications have also raised concerns regarding their possible toxicological impacts on human health. The actual issue stems from the absence of systematic data on ENM exposure-mediated health hazards. In this direction, a comprehensive exploration on the health-related consequences, especially with respect to endocrine disruption-related metabolic disorders, is largely lacking. The reasons for the rapid increase in diabetes and obesity in the modern world remain largely unclear, and epidemiological studies indicate that the increased presence of endocrine disrupting chemicals (EDCs) in the environment may influence the incidence of metabolic diseases. Functional similarities, such as mimicking natural hormonal actions, have been observed between the endocrine-disrupting chemicals (EDCs) and ENMs, which supports the view that different types of NMs may be capable of altering the physiological activity of the endocrine system. Disruption of the endocrine system leads to hormonal imbalance, which may influence the development and pathogenesis of metabolic disorders, particularly type 2 diabetes mellitus (T2DM). Evidence from many in vitro, in vivo and epidemiological studies, suggests that ENMs generally exert deleterious effects on the molecular/hormonal pathways and the organ systems involved in the pathogenesis of T2DM. However, the available data from several such studies are not congruent, especially because of discrepancies in study design, and therefore need to be carefully examined before drawing meaningful inferences. In this review, we discuss the outcomes of ENM exposure in correlation with the development of T2DM. In particular, the review focuses on the following sub-topics: (1) an overview of the sources of human exposure to NMs, (2) systems involved in the uptake of ENMs into human body, (3) endocrine disrupting engineered nanomaterials (EDENMs) and mechanisms underlying the pathogenesis of T2DM, (4) evidence of the role of EDENMs in the pathogenesis of T2DM from in vitro, in vivo and epidemiological studies, and (5) conclusions and perspectives.

The Pros and Cons of the Use of Laser Ablation Synthesis for the Production of Silver Nano-Antimicrobials

Silver nanoparticles (AgNPs) are well-known for their antimicrobial effects and several groups are proposing them as active agents to fight antimicrobial resistance. A wide variety of methods is available for nanoparticle synthesis, affording a broad spectrum of chemical and physical properties. In this work, we report on AgNPs produced by laser ablation synthesis in solution (LASiS), discussing the major features of this approach. Laser ablation synthesis is one of the best candidates, as compared to wet-chemical syntheses, for preparing Ag nano-antimicrobials. In fact, this method allows the preparation of stable Ag colloids in pure solvents without using either capping and stabilizing agents or reductants. LASiS produces AgNPs, which can be more suitable for medical and food-related applications where it is important to use non-toxic chemicals and materials for humans. In addition, laser ablation allows for achieving nanoparticles with different properties according to experimental laser parameters, thus influencing antibacterial mechanisms. However, the concentration obtained by laser-generated AgNP colloids is often low, and it is hard to implement them on an industrial scale. To obtain interesting concentrations for final applications, it is necessary to exploit high-energy lasers, which are quite expensive. In this review, we discuss the pros and cons of the use of laser ablation synthesis for the production of Ag antimicrobial colloids, taking into account applications in the food packaging field.
