Abstract null null Solution acidification exists under some physiological conditions (e.g. lysosomes in cells) and diseases (e.g. atherosclerosis, tumors, etc.). It is poorly understood whether and how acidification influences the size and biomechanical (stiffness and stickiness) properties of native Low-density lipoprotein (LDL) and its oxidized form (oxLDL) which plays a vital role in atherogenesis and tumorigenesis. Atomic force microscopy (AFM) evaluated that gradient acidification from pH 7...
Abstract null null Mineral coatings manipulate surface properties such as roughness, porosity, wettability and surface energy. Properties that are known to determine cell behaviour. Therefore, mineral coatings can potentially be used to manipulate cell fate. This paper studies mineral-cell interactions through coatings in a stacked cell culture platform. Minerals were chosen according to their influence on Human Dermal Fibroblasts (HDFs): calcium carbonate, calcium sulphates, and kaolin. Mineral...

Abstract null null Recently, increased attention has been focused on antibacterial photodynamic therapy (APDT) to treat multidrug-resistant bacterial infection due to the antibiotic abuse. Methylene blue has been used as a kind of efficient and cheap commercial photosensitizer in APDT. However, due to high hydrophilicity, methylene blue is not able to be transcellular intaken and accumulated efficiently. To promote accumulation and APDT efficiency of methylene blue, lipopeptide surfactin-methyle...

The increasing need for agricultural production on the one hand, and requirements for greener and more sustainable agricultural practices on the other, have led to a growing demand for efficient and eco-friendly materials for the delivery of agrochemicals. Here we describe, the use of layered double hydroxide (LDH) particles as a carrier for a plant hormone. Magnesium-aluminum LDH intercalated with indole-3-acetic acid (IAA) was synthesized by co-precipitation method, characterized, and examined...

Abstract null null Small organic molecules have been extensively applied to achieve enzymatic inhibition. Although numerous efforts have been made to deliver efficient inhibitors, small inhibitors applications are hindered by many drawbacks. Moreover, reporters comprising nanoparticle inhibitory activity against enzymes are very scarce in the literature. In this scenario, carbon nanodots (CDs) emerge as promising candidates for efficient enzyme inhibition due to their unique properties. Here, CD...
Abstract null null Featured with a three-dimensional network structure, electrostatic spinning nanofibrous membranes can maintain the hygroscopic balance in the wound place and promote the wound healing, thus have been extensively studied as a promising wound healing dressing. In this study, amoxicillin (AMX), MXene, and polyvinyl alcohol (PVA) were mixed and electrospun into an antibacterial nanofibrous membrane (MXene-AMX-PVA nanofibrous membrane). In the composite nanofibrous membrane, the PV...
Abstract null null Presently, multifunctional silver nanoparticles (AgNPs) show a rapid growth in various commercial applications, leading to increasing demand for new eco-friendly manufacturing technologies. An array of genetic engineering tools can be used to increase the yield in the production of AgNPs using various biological systems. The present study reports a green chemistry approach for the biological synthesis of AgNPs using extracts from non-transformed callus, rolC-transgenic callus ...

Abstract null null Macrophages perform multiple functions in both inflammation and wound healing, and are one of the fore front cells during implant osseointegration that influence subsequent process. Essential trace element modification may effectively modulate titanium implant surface biological properties. In this work, strontium (Sr) incorporated micro/nano rough titanium surfaces (Sr-SLA) was fabricated by hydrothermal treatment, and immunoreaction of macrophages was further investigated. I...
Titanium and titanium alloys have broad applications in orthopedic implants due to their excellent mechanical properties and biocompatibility. The biological activity of the metallic implants can be improved by implementing a nano-hydroxyapatite (nano-HA) coating, while it is still challenging to synthesize uniform and stable nano-HA on the metallic materials. The characterization results confirmed that the nanotube array with a diameter of 87 ± 21 nm and a length of 8.1 ± 1.3 μm is achieved by ...

Abstract null null Sophorolipids (SLs) constitute a group of unique biosurfactants (BS) in the light of their outstanding properties, among which their antimicrobial activities stand out. SLs can exist mainly in an acidic and a lactonic form, both of which display inhibitory activity. Given the amphipathic nature of SLs it is feasible that these antimicrobial actions are the result of the perturbation of the physicochemical properties of targeted membranes. Thus, in this work we have carried out...
