Anti-biofouling strategies for implantable biosensors of continuous glucose monitoring systems

《化学科学与工程前沿（英文）》 2023年 第17卷 第12期   页码 1866-1878 doi: 10.1007/s11705-023-2340-x

摘要： Continuous glucose monitoring (CGM) systems play an increasingly vital role in the glycemic control of patients with diabetes mellitus. However, the immune responses triggered by the implantation of poorly biocompatible sensors have a significant impact on the accuracy and lifetime of CGM systems. In this review, research efforts over the past few years to mitigate the immune responses by enhancing the anti-biofouling ability of sensors are summarized. This review divided these works into active immune engaging strategy and passive immune escape strategy based on their respective mechanisms. In each strategy, the various biocompatible layers on the biosensor surface, such as drug-releasing membranes, hydrogels, hydrophilic membranes, anti-biofouling membranes based on zwitterionic polymers, and bio-mimicking membranes, are described in detail. This review, therefore, provides researchers working on implantable biosensors for CGM systems with vital information, which is likely to aid in the research and development of novel CGM systems with profound anti-biofouling properties.

Enhanced permeability and biofouling mitigation of forward osmosis membranes via grafting graphene quantum

《化学科学与工程前沿（英文）》 2023年 第17卷 第10期   页码 1470-1483 doi: 10.1007/s11705-023-2329-5

摘要： In this paper, graphene oxide quantum dots with amino groups (NH2-GOQDs) were tailored to the surface of a thin-film composite (TFC) membrane surface for optimizing forward osmosis (FO) membrane performance using the amide coupling reaction. The results jointly demonstrated hydrophilicity and surface roughness of the membrane enhanced after grafting NH2-GOQDs, leading to the optimized affinity and the contact area between the membrane and water molecules. Therefore, grafting of the membrane with a concentration of 100 ppm (TFC-100) exhibited excellent permeability performance (58.32 L·m–2·h–1) compared with TFC membrane (16.94 L·m–2·h–1). In the evaluation of static antibacterial properties of membranes, TFC-100 membrane destroyed the cell morphology of Escherichia coli (E. coli) and reduced the degree of bacterial adsorption. In the dynamic biofouling experiment, TFC-100 membrane showed a lower flux decline than TFC membrane. After the physical cleaning, the flux of TFC-100 membrane could recover to 96% of the initial flux, which was notably better than that of TFC membrane (63%). Additionally, the extended Derjaguin–Landau–Verwey–Overbeek analysis of the affinity between pollutants and membrane surface verified that NH2-GOQDs alleviates E. coli contamination of membrane. This work highlights the potential applications of NH2-GOQDs for optimizing permeability and biofouling mitigation of FO membranes.

摘要： Composite biological and inorganic fouling occurs in plate heat exchangers (PHEs) using treated sewage as heat transfer medium, which lowers the heat transfer coefficient and increases the frictional resistance. In order to optimize the heat exchange process and improve the anti-fouling strategies, the dynamic behavior of composite fouling at a vertical surface of stainless steel (ANSI 316L) was investigated under typical conditions of PHEs. The growth curves of composite fouling were obtained. The evolution of composite fouling was characterized by means of environmental scanning electron microscopy (ESEM). Backscattered Electron Image (BEI) and energy dispersive X-ray spectrometry (EDS) were used as aids in interpreting the results. The experimental results show that a preliminary stage of a 6-day period with a low fouling growth rate exists during the composite fouling development. A significant change of the fouling growth rate happens after the preliminary stage during which the bacterial behaviors at the surface could be recorded clearly. After the preliminary stage, a space net-shape, mainly consisting of bacteria, extracellular products (EPS) and inorganic particles, could be established on the surface of the fouling layer. The change of fouling growth rate occurs synchronously with the evolution.

氯化水与地表水导致的膜污染对比解析——生物污染特性和微生物探究 Article

摘要：

氯在城市水处理过程中通常用于灭活病原体和预防水媒疾病，但是目前尚不清楚其作为一种预处理技术是否能够有效地缓解超滤过程中产生的膜污染。在本研究中，我们探究了自来水在重力驱动膜过滤系统中对生物膜的形成及生物污染的影响。同时，未处理的地表水（湖水）所形成的生物膜/生物污染也进行了对比研究。研究表明，自来水过滤系统产生了比湖水更严重的膜污染，而且多糖和eDNA的含量更高。其生物膜形态致密，但是湖水形成的生物膜是多孔、类似蜘蛛网状的结构，猜测可能与生物膜中的细菌有关。16S rRNA测序结果表明，Xanthobacter在自来水形成的生物膜中占据优势地位。此外，研究发现膜的亲、疏水性对膜污染特性和微生物群落的影响较小。本研究揭示了耐氯细菌在膜污染形成中的重要作用，更深入地认识了膜污染，可为寻求有效的膜污染控制方法提供帮助。

摘要：

OsMFC can simultaneously recover electricity and water from wastewater.

Membrane fouling played an important role in flux decline of FO membrane in OsMFCs.

Biofouling was the major fouling of the FO membrane in OsMFCs.

The growth of biofouling layer on the FO membrane can be divided into three stages.

Microorganisms were the dominant biofoulant in the biofouling layer.

Assessment of oxidative and UV-C treatments for inactivating bacterial biofilms from groundwater wells

摘要： Microorganisms are ubiquitous in natural environments and in water supply infrastructure including groundwater wells. Sessile-state microorganisms may build up on well surfaces as biofilms and, if excessive, cause biofouling that reduces well productivity and water quality. Conditions can be improved using biocides and other traditional well rehabilitation measures; however, biofilm regrowth is inevitable given the continuous introduction of microorganisms from the surrounding environment. Alternative and less invasive well maintenance approaches are desirable for reducing biofilm densities while also minimizing harmful disinfection-by-products. The primary objective of this research was to evaluate effectiveness of alternative treatments for inactivating microorganisms comprising biofilms. A novel approach was designed for in situ growth of biofilms on steel coupons suspended from ‘chandeliers’. After more than 100 days of in situ growth, biofilms were harvested, sampled, and baseline biofilm densities quantified through cultivation. Ultraviolet-C (UV-C) and oxidative treatments including hydrogen peroxide (H O ), ozone (O ) and mixed oxidants were then applied to the biofilms in laboratory-scale treatments. Microbial inactivation was assessed by comparing treated versus baseline biofilm densities. H O was the most effective treatment, and decreased density below baseline by as much as 3.1 orders of magnitude. Mixed oxidants were effective for the well having a lower density biofilm, decreasing density below baseline by as much as 1.4 orders of magnitude. Disparity in the response to treatment was apparent in the wells despite their spatial proximity and common aquifer source, which suggests that microbiological communities are more heterogeneous than the natural media from which they originate.
