Development of Green-Synthesized Carbon-Based Nanoparticle for Prevention of Surface Wound Biofilm
Appl Biochem Biotechnol. 2023 Sep 16. doi: 10.1007/s12010-023-04695-4. Online ahead of print.ABSTRACTThe development of microbial biofilm occurs with the adherence of the microbial cells on biotic and abiotic surfaces with the help of pili and with extracellular polymeric substances. The surfaces on which biofilm formation take place can be inert, abiotic, or biotic. The sessile microbial cells behave differently from their planktonic counterpart. The biofilm developed by Alcaligenes faecalis is responsible for the development of skin and soft-tissue infection. It was observed that green-synthesized carbon nanoparticles (N...

Effects of polyvinylchloride microplastics on the toxicity of nanoparticles and antibiotics to aerobic granular sludge: Nitrogen removal, microbial community and resistance genes
Environ Res. 2023 Sep 14:117151. doi: 10.1016/j.envres.2023.117151. Online ahead of print.ABSTRACTCopper oxide nanoparticles (CuO NPs) and ciprofloxacin (CIP) have ecological risk to humans and ecosystems. Polyvinylchloride microplastics (PVC MPs), as a representative of microplastics, may often coexist with CuO NPs and CIP in wastewater treatment systems due to their widespread application. However, the co-impact of PVC MPs in wastewater systems contained with CuO NPs and CIP on nitrogen removal and ecological risk is not clear. In this work, PVC MPs co-impacts on the toxicity of CuO NPs and CIP to aerobic granular sludge...

Nanoparticles and nanofiltration for wastewater treatment: From polluted to fresh water
Environ Res. 2023 Sep 14;238(Pt 1):117114. doi: 10.1016/j.envres.2023.117114. Online ahead of print.ABSTRACTWater pollution poses significant threats to both ecosystems and human health. Mitigating this issue requires effective treatment of domestic wastewater to convert waste into bio-fertilizers and gas. Neglecting liquid waste treatment carries severe consequences for health and the environment. This review focuses on intelligent technologies for water and wastewater treatment, targeting waterborne diseases. It covers pollution prevention and purification methods, including hydrotherapy, membrane filtration, mechanical ...

The linkage between microRNA and cancer and its delivery as cancer therapy: A mini-review
Cell Mol Biol (Noisy-le-grand). 2023 Jul 31;69(7):7-18. doi: 10.14715/cmb/2023.69.7.2.ABSTRACTThe central dogma of molecular biology was no longer "central" after ground-breaking discoveries conveyed gene expression involves more complex physiological functions in cancer pathogenesis over the last decade. MicroRNAs (miRNAs) are short non-coding RNA that regulate gene expression, affecting key molecular pathways involved in sustaining the proliferative signalling for tumour development, evasion of cellular death, invasion, angiogenesis, as well as metastasis in a plethora of cancer types. MiRNA expression is dysregulated in...

Glucosylated Hybrid TiO2/Polymer Nanomaterials for Actively Targeted Sonodynamic Therapy of Cancer
Researchers introduce a novel anticancer sonodynamic platform, namely glucosylated hybrid ceramic/polymeric nanoparticles. These precisely size-controlled nanoparticles enhance tumor-specific delivery using a surface modification with a glucose analog. When combined with therapeutic ultrasound, these nanoparticles dramatically reduce tumor growth and prolong the survival of rhabdomyosarcoma-bearing mice. This innovative strategy shows great potential for local anticancer treatment. AbstractSonodynamic therapy (SDT) is an anti-cancer therapeutic strategy based on the generation of reactive oxygen species (ROS) upon local ul...

Negatively Charged Hydrophobic Carbon Nano ‐Onion Interfacial Layer Enabling High‐Rate and Ultralong‐Life Zn‐Based Energy Storage
A negatively charged hydrophobic carbon nano-onion (CNO) interfacial layer to realize ultrastable and high-rate Zn anodes is reported, enabling high-performance Zn-based electrochemical energy storage. Its hydrophobicity blocks active water and reduces the Zn2+ desolvation barrier, and the negatively charged CNOs adsorb Zn2+ and repel SO42 − to homogenize Zn2+ flux, accelerate Zn2+ desolvation and suppress the self-corrosion of Zn anodes. AbstractZn-based electrochemical energy storage (EES) systems are attracting more attention, whereas their large-scale application is restricted by the dendrite and parasitic reaction-c...

Carbon Dots: From Synthesis to Unraveling the Fluorescence Mechanism
Emerging carbon-based nanoparticles (e.g., carbon dots) have been proven to be promising materials for biological application. This review focuses on current understanding of fluorescence mechanisms, and also summarizes recent advances in synthesis and functionalization of carbon dots. An in-depth analysis of synthetic precursors, surfaces, defects, and energy states is presented in this review. AbstractCarbon dots (CDs) being a new type of carbon-based nanomaterial have attracted intensive interest from researchers owing to their excellent biophysical properties. CDs are a class of fluorescent carbon nanomaterials that ha...

Brownian Relaxation Shakes and Breaks Magnetic Iron Oxide ‐Polymer Nanocomposites to Release Cargo
Iron oxide nanoparticles larger than ≈15 nm react to alternating magnetic fields by Brownian relaxation resulting in tumbling and shaking. It is shown that this shaking motion partially detaches and cleaves polymer coatings to release cargo molecules. As opposed to typical hyperthermia applications, this release mechanism is heat-fr ee hence broadening the application space of magnetic nanoparticles. AbstractMagnetic nanoparticles (NPs) are widely employed for remote controlled molecular release applications using alternating magnetic fields (AMF). Yet, they intrinsically generate heat in the process by N éel relaxatio...

High-performance Thin-Film Solar Solar Cells Based on AlGaAs/GaAs Heterojunction and Localized Surface Plasmon Oscillations
AbstractTraditional solar cells face the challenges of high cost and limited conversion efficiency, which seriously limits their promotion in practical applications. Therefore, this article proposes a novel GaAs thin-film solar cell based on algae ’s/GaAs heterojunction. It utilizes the finite difference time domain (FDTD) method to simulate the propagation of electromagnetic waves and the process of light absorption in the cell under specific boundary conditions. The simulation experimental results demonstrate that the introduction of indi um tin oxide (ITO) and Ag plasma into solar cell structure significantly enhances...
