Cell-free RNA(cf RNA) allows assessment of health, status, and phenotype of a variety of human organs and is a potential biomarker to non-invasively diagnose numerous diseases. Nevertheless, there is a lack of highly efficient and bias-free cf RNA isolation technologies due to the low abundance and instability of cf ***, we developed a reproducible and high-efficiency isolation technology for different types of cell-free nucleic acids(containing cf RNA and viral RNA) in serum/plasma based on the inclusion of nucleic acids by metal-organic framework(MOF) materials, which greatly improved the isolation efficiency and was able to preserve RNA integrity compared with the most widely used research kit method. Importantly, the quality of cf RNA extracted by the MOF method is about 10-fold that of the kit method, and the MOF method isolates more than three times as many different RNA types as the kit method. The whole transcriptome mapping characteristics of cf RNA in serum from patients with liver cancer was described and a cf RNA signature with six cf RNAs was identified to diagnose liver cancer with high diagnostic efficiency(area under curve = 0.905 in the independent validation cohort) using this MOF method. Thus, this new MOF isolation technique will advance the field of liquid biopsy, with the potential to diagnose liver cancer.

This study examined the effect of Zn2+ ion substitution on ZnxMn(1-x) Fe2O4 nanoparticles (x = 0.2, 0.4, 0.6, 0.8) towards signal Surface Plasmon Resonance (SPR). The co-precipitation method synthesised the nanoparticles at a temperature of 90°C. The X-Ray Diffraction (XRD) results showed a polycrystalline structure with a crystallite size varied from 19.05 nm to 19.77 nm. In addition, as the Zn element increased in the ZnxMn(1-x)Fe2O4 nanoparticles, the degree of crystallinity increased by 21.72%, respectively. The optical properties of the nanoparticles ZnxMn(1-x) Fe2O4 indicate absorbance at wavelengths of 330.36–331.74 nm. The absorbance level increased as the Zn element decreased, resulting a direct optical gap of 3.47 eV and an indirect optical gap of 3.23 eV. The Attenuated Total Reflection (ATR) curve in the SPR biosensor indicated a shift in the reflective angle of the Prism/Au/Air configuration, which is 47.78° on Prisma/Au/nanoparticle of Zn0.8Mn0.2Fe2O4/air by 50.75°, and the prism/Au/nanoparticle of Zn0.2Mn0.8Fe2 O4/air by 51.04°. The substitution of Zn ions in the compound Zn x Mn(1-x)Fe2O4 affects the resulting ATR curve. The shift in the SPR angle is caused by changes in the refractive index in each layer which is influenced by the concentration of each material which has an impact on the absorbance ability and photon reflectance. This research has the potential to continue with the testing of dielectric and magnetic properties, as well as special testing for biological analytes compatible with ZnxMn(1-x)Fe2O4 nanoparticles. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

A series of enantiopure triptycene-based one-handed helical ladder polymers containing π-extended achiral segments with naphthalene, fluorene, and carbazole spacers was synthesized through quantitative and chemoselective ladderization of the corresponding precursor polymers with random-coil conformations. The helical handedness (right- or left-handed) and geometry (loose coil or ribbon) of the resulting ladder polymers were readily modulated by tuning the structure of the achiral spacers despite the incorporation of the same point chirality of the triptycene unit. All the helical secondary structures are stable and robust due to the shape-persistent ladder structures, showing the characteristic and environment-independent chiroptical properties. © 2023.

Modified polysaccharides are widely used as polymers for medical and biomedical purposes. Among them, the products with a crosslinked macromolecular structure occupy an important place. For instance, using N-derivatives of glutamic acid as a crosslinking agent makes it is possible to obtain non-toxic biodegradable polymer materials. In the current work, the results of study on the polysaccharides modification with N-derivatives of glutamic acid via the Steglich esterification reaction are provided. The factors influencing the efficiency of developed synthetic approach were considered, and the structure and composition of the obtained reaction products were investigated. The reaction was shown to proceed successfully by exploiting both carboxyl groups of N-derivatives of glutamic acid, resulting in the cross-linking of polysaccharide molecules under mild conditions. The study of the properties of the obtained products and the NMR study of their structure and composition showed that two fundamentally different polymers were formed—macromolecules with branched and crosslinked structures. The latter, under certain reaction conditions, formed microhydrogels while dispersing in water. Meanwhile, the branched macromolecules were capable of forming self-stabilized aqueous dispersions. Thus, the article presents the research results on the creation of novel polymers for potential medical applications. © 2023, King Abdulaziz City for science and Technology.

Conductive hydrogels with near-infrared(NIR) photothermal effects are a promising class of smart materials. They integrate the unique properties of hydrogels—such as flexibility and biocompatibility—with enhanced electrical conductivity and photothermal responsiveness. These materials use NIR light to induce localized heating through photothermal conversion, enabling precise control over physicochemical properties, including conductivity, mechanical strength, and antibacterial activity. However, comprehensive reviews in this field are limited. This article systematically classifies photothermal materials into four categories: conjugated polymers, carbon-based nanomaterials, inorganic nanomaterials, and metal-phenolic networks, and explains their mechanisms. We highlight recent advancements in applications such as smart wound dressings, soft actuators, and responsive sensors, while addressing challenges like optimizing photothermal efficiency, balancing biocompatibility with conductivity, and scaling up production. By providing a comprehensive analysis of material design strategies and applicationspecific innovations, this review aims to guide future research toward next-generation multifunctional hydrogels for advanced biomedical and technological applications.

Waste generation from food manufacturing facilities poses a serious hazard like environmental degradation, water pollution, and land pollution due to its high nutrient composition. Specifically, solid waste(powder) disposal requires additional energy sources in terms of scientific treatment, structured collection, and disposal packaging according to the safety regulation. Thus, this research discusses the viewpoint of integrating food processing waste as an organic carbon source with BG-11 medium for Chlorella vulgaris(FSP-E) growth. The food processing waste powders investigated in this study were obtained from milk, and biscuit manufacturing facilities. The culture medium was modified by combining both BG-11 and food processing waste powders to identify the optimal algal growth and biochemical *** to the microalgae grown in BG-11 alone(IBG), the combination of biscuit waste and IBG produced higher biomass concentration(44%), with increased lipid(11%), protein(20%), and carbohydrate(57%) contents. Chlorella vulgaris was able to uptake nutrients from the culture medium with combination of food processing waste and IBG thus enhancing its growth. The results obtained also indicate that an integrated culture system using food processing waste and synthetic sources can generate energy out of waste by improving the bio-composition of the microalgae biomass.
