“…is a mixture of two sugar alcohols: gluco-mannitol and gluco-sorbitol. It has relatively low solubility in water at low temperatures (25 g/100 g at 25°C) with a high tendency to crystallize [46]. However, AA (C 6 H 8 O 6 ) is a polar organic molecule that has high water solubility (290 g/L at 20°C) [47], forming more homogenous structure.…”

In this paper we present a compact microfluidic platform for selective detection of ascorbic acid. The microfluidic chip was fabricated by xurography technique with microfluidic channel placed between the silver electrodes. To increase the conductivity of the platform and enhance electron transfer process, a graphene sheet was deposited in the gap between the electrodes. The suspension of tablets with ascorbic acid and a mixture of ascorbic acid and isomalt, a sugar substitute, were injected into the microfluidic channel. Measuring electrical parameters at the silver contacts, it was possible to successfully differentiate ascorbic acid from isomalt. The sensing mechanism of the developed microfluidic platform is based on the increase of the overall conductivity with the increase of the concentration of AA, resulting in the decrease of the resistive parameters and increase of the capacitive parameters of the proposed equivalent electrical circuit. The addition of graphene was found to improve the response linearity by 5.28% and lower the limit of detection and quantification by 12%, compared to the reference structure without graphene.

“…Ester type of surfactants are less toxic than the ethers and are biodegradable by esterase enzymes. Amongst the most widely used alkyl esters we can distinguish Span® and Tween® esters, which are respectively fatty acid esters of sorbitan or of a multi-PEGylated version of sorbitan [115,124]. As in the case of phospholipidic supramolecular assemblies, modification with PEG can enhance the half-life of niosomes by reducing their uptake from the MPS [125][126][127].…”

Molecular bionics – engineering biomaterials at the molecular level using biological principles

et al. 2019

Life and biological units are the result of the supramolecular arrangement of many different types of molecules, all of them combined with exquisite precision to achieve specific functions. Taking inspiration from the design principles of nature allows engineering more efficient and compatible biomaterials. Indeed, bionic (from bion-, unit of life and -ic, like) materials have gained increasing attention in the last decades due to their ability to mimic some of the characteristics of nature systems, such as dynamism, selectivity, or signalling. However, there are still many challenges when it comes to their interaction with the human body, which hinder their further clinical development. Here we review some of the recent progress in the field of molecular bionics with the final aim of providing with design rules to ensure their stability in biological media as well as to engineer novel functionalities which enable navigating the human body.

“…Respecto a los efectos benéficos para la salud, el manitol es parcialmente absorbido en el intestino delgado y puede llegar hasta el colon y ser degradado por bacterias produciendo ácidos grasos de cadena corta confiriendo efectos beneficiosos en la salud del huésped. Por ello, la adición de manitol a los alimentos da lugar a productos con valor nutricional adicional (alimentos funcionales) (Munster y Nagengast, 1993;Schiweck H, 1994;Liong y Shah, 2005). Sin embargo, su ingesta diaria no debe exceder los 20 g por persona ya que posee un bajo umbral laxante pudiendo provocar la producción de gas y diarrea.…”

Polyols such as mannitol, erythritol, sorbitol, and xylitol are naturally found in fruits and vegetables and are produced by certain bacteria, fungi, yeasts, and algae. These sugar alcohols are widely used in food and pharmaceutical industries and in medicine because of their interesting physicochemical properties. In the food industry, polyols are employed as natural sweeteners applicable in light and diabetic food products. In the last decade, biotechnological production of polyols by lactic acid bacteria (LAB) has been investigated as an alternative to their current industrial production. While heterofermentative LAB may naturally produce mannitol and erythritol under certain culture conditions, sorbitol and xylitol have been only synthesized through metabolic engineering processes. This review deals with the spontaneous formation of mannitol and erythritol in fermented foods and their biotechnological production by heterofermentative LAB and briefly presented the metabolic engineering processes applied for polyol formation.
