Development of reinforced starch-hyaluronic acid-based nanocomposite films containing halloysite nanotubes-allantoin for biomedical application.

Polymer-based nanocomposite films have recently gained attention for their potential in tissue engineering and wound dressing applications. This study focuses on developing nanocomposite films using starch (S) and hyaluronic acid (HA), enhanced with halloysite nanotubes (HNTs) loaded with allantoin (S-HA-HNTs-Aln), and incorporating carbon quantum dots (QDs) as softeners and crosslinkers. Tensile testing revealed that biofilms containing 100 mg of HNTs exhibited the highest tensile strength.

Ultrasound-assisted encapsulating folic acid-based carbon quantum dots within breast cancer cell-derived exosomes as a co-receptors-mediated anticancer nanocarrier for enhanced breast cancer therapy.

The nonspecific nature of cancer drug delivery often results in substantial toxic side effects during treatments for breast cancer. To mitigate these negative outcomes, our approach involves loading methotrexate (MTX) within carbon quantum dots (CQDs) synthesized from folic acid, which are then enveloped in exosomal membranes obtained from breast cancer cells (Ex@MTX-CQDs). Analysis utilizing nanoparticle tracking techniques has demonstrated that these Ex@MTX-CQDs maintain the physical and biochemical properties of their exosomal precursors.

A review on the impacts of metal/metal nanoparticles on characteristics of hydrogels: Special focus on carbohydrate polymers.

Hydrogels with very interesting properties such as high water content, porosity, swelling, and mimicking the structure of the extracellular matrix (ECM) are promising candidates for a variety of applications. Recently, great efforts are being made to improve the shape and functionality of three-dimensional (3D) hydrogels. One of the most promising approaches is the incorporation of metal or metal nanoparticles (NPs) into hydrogels made of natural and synthetic polymers such as proteins, carbohydrates (i.

Recent progress in tannic acid based approaches as a natural polyphenolic biomaterial for cancer therapy: A review.

Significant advancements have been noticed in cancer therapy for decades. Despite this, there are still many critical challenges ahead, including multidrug resistance, drug instability, and side effects. To overcome obstacles of these problems, various types of materials in biomedical research have been explored.

Matricaria chamomilla essential oil-loaded hybrid electrospun nanofibers based on polycaprolactone/sulfonated chitosan/ZIF-8 nanoparticles for wound healing acceleration.

Recently, developing antibacterial wound dressings based on biomaterials display good biocompatibility and the potential to accelerate wound healing. For this aim, we prepared eco-friendly and biodegradable nanofibers (NFs) based on N-(3-sulfopropyl)chitosan/ poly (ε-caprolactone) incorporated by zeolite imidazolate framework-8 nanoparticles (ZIF-8 NPs) and chamomile essential oil (MCEO) via the electrospinning technique for their efficacy as wound dressing scaffolds. Fabricated NFs were characterized and studied for their structural, morphological, mechanical, hydrophilic, and thermal stability properties.

Review of Physical Layer Security in Molecular Internet of Nano-Things.

Molecular networking has been identified as a key enabling technology for Internet-of-Nano-Things (IoNT): microscopic devices that can monitor, process information, and take action in a wide range of medical applications. As the research matures into prototypes, the cybersecurity challenges of molecular networking are now being researched on at both the cryptographic and physical layer level. Due to the limited computation capabilities of IoNT devices, physical layer security (PLS) is of particular interest.
