“…The cooper metal framework (Cu-MOF) was synthesized according to the previously reported method by [61] and [48]. Briefly, copper nitrate trihydrate (0.493 g), 1.4-H 2 BDC (0.453g) and TED (0.32 g) were dissolved in 100 mL of DMF, and the mixture was sonicated to obtain a homogenous solution.…”

“…They have been applied to numerous areas of study, like catalysis, separation, biomedical imaging, clean energy, drug delivery and gas storage and separation [45,46]. In biosensing applications, these materials play a the role as biomimetic components [47], offering improved sensitivities for detection of certain analytes [48]. Gamero et al reported an electrochemical biosensor based on three-dimensional ordered macroporous gold film electrodes, using covalently immobilized lactate oxidase, to obtain an increased conductivity and stability for lactate sensing [49].…”

Lactate concentration is studied as an indicator of physical performance in sports activities, and is also analyzed in health care applications, as well as in the food and cosmetic industries. This organic acid is routinely determined in different concentration ranges, depending on the type of samples for analysis. This paper describes the development of a screen-printed lactate oxidase (LO) based biosensor to determine lactate in broad concentration range. The Cu-MOF (copper metallic framework) crosslinking of 0.25U LO in a chitosan layer, allows to determine the enzymatic product generated on a platinum modified working electrode, at 0.15 V (vs SPE Ag/AgCl). The biosensor responds linearly in two different concentration ranges: a first catalysis range of 14.65 µA mM, from 0.75 µM to 1 mM, followed by a saturation zone from 1 to 4 mM, after which a substrate enzymatic inhibition of 0.207 µA mM, is observed up to 50 mM. These two ranges of analysis would allow the biosensor to be used for the determination of lactate in different types of samples, with low and high content of lactate. The method reproducibility was kept below 7% and a limit of detection of 0.75 µM was obtained. The device was successfully used in the determination of lactate in sweat and saliva, as a low cost noninvasive analysis, and also in wine samples.

“…For example, single enzyme nanogels of glucose oxidase are able to assemble into ordered and highly stable films by means of coordination polymers and divalent metals (Rodriguez-Abetxuko et al, 2019b). Also, Cu 2+ -based tyrosinase MOFs can be used to fabricate a bisphenol A biosensor (Wang et al, 2015;Lu et al, 2016).…”

The number of methodologies for the immobilization of enzymes using polymeric supports is continuously growing due to the developments in the fields of biotechnology, polymer chemistry, and nanotechnology in the last years. Despite being excellent catalysts, enzymes are very sensitive molecules and can undergo denaturation beyond their natural environment. For overcoming this issue, polymer chemistry offers a wealth of opportunities for the successful combination of enzymes with versatile natural or synthetic polymers. The fabrication of functional, stable, and robust biocatalytic hybrid materials (nanoparticles, capsules, hydrogels, or films) has been proven advantageous for several applications such as biomedicine, organic synthesis, biosensing, and bioremediation. In this review, supported with recent examples of enzyme-protein hybrids, we provide an overview of the methods used to combine both macromolecules, as well as the future directions and the main challenges that are currently being tackled in this field.

“…Because of these properties, MOF-199 is a very potential candidate for gas storage [4], catalysis [5] and sensing applications [6,7]. Especially, MOF-199 has been employed as an electrode modifier to detect glucose [8], to simultaneously determine hydroquinone and catechol [9], and to detect bisphenol A rapidly [10].…”

In the present paper, a comparative study on the synthesis of the metal-organic framework-199 (MOF-199) using the microwave and solvothermal method was demonstrated. The obtained materials were characterized using X-ray diffraction, scanning electron microscope, nitrogen adsorption/desorption isotherms and thermal gravity. The microwave synthesis of MOF-199 was compared with the conventional hydrothermal synthesis. The results showed that MOF-199 could be obtained in a much shorter time with improved yield and textural properties under the microwave irradiation. It is supposed that the microwave energy emitted fast and uniformly, creating nuclei through the solution which quickly grew to crystals, and both the nucleation and crystallization were accelerated. This made the microwave synthesis advantageous over the solvothermal synthesis.
