Hybrid-Based Wound Dressings: Combination of Synthetic and Biopolymers.

Most commercialized wound dressings are polymer-based. Synthetic and natural polymers have been utilized widely for the development of wound dressings. However, the use of natural polymers is limited by their poor mechanical properties, resulting in their combination with synthetic polymers and other materials to enhance their mechanical properties. Natural polymers are mostly affordable, biocompatible, and biodegradable with promising antimicrobial activity. They have been further tailored into unique hybrid wound dressings when combined with synthetic polymers and selected biomaterials. Some

Topological and Multivalent Effects in Glycofullerene Oligomers as EBOLA Virus Inhibitors.

The synthesis of new biocompatible antiviral materials to fight against the development of multidrug resistance is being widely explored. Due to their unique globular structure and excellent properties, [60]fullerene-based antivirals are very promising bioconjugates. In this work, fullerene derivatives with different topologies and number of glycofullerene units were synthesized by using a SPAAC copper free strategy. This procedure allowed the synthesis of compounds 1-3, containing from 20 to 40 mannose units, in a very efficient manner and in short reaction times under MW irradiation. The gly

A polymer index-matched to water enables diverse applications in fluorescence microscopy.

We demonstrate diffraction-limited and super-resolution imaging through thick layers (tens-hundreds of microns) of BIO-133, a biocompatible, UV-curable, commercially available polymer with a refractive index (RI) matched to water. We show that cells can be directly grown on BIO-133 substrates without the need for surface passivation and use this capability to perform extended time-lapse volumetric imaging of cellular dynamics 1) at isotropic resolution using dual-view light-sheet microscopy, and 2) at super-resolution using instant structured illumination microscopy. BIO-133 also enables immob

3D Topology Optimization and Mesh Dependency for Redesigning Locking Compression Plates Aiming to Reduce Stress Shielding.

Current fixation plates for bone fracture treatments are built with biocompatible metallic materials such as stainless steel, titanium, and its alloys (e.g., Ti6Al4V). The stiffness mismatch between the metallic material of the plate and the host bone leads to stress shielding phenomena, bone loss, and healing deficiency. This paper explores the use of three dimensional topology-optimization, based on compliance (i.e., strain energy) minimization, reshaping the design domain of three locking compression plates (four-screw holes, six-screw holes, and eight-screw holes), considering different vo

Gold Nanoparticle-Functionalized Reverse Thermal Gel for Tissue Engineering Applications.

Utilizing polymers in cardiac tissue engineering holds promise for restoring function to the heart following myocardial infarction, which is associated with grave morbidity and mortality. To properly mimic native cardiac tissue, materials must not only support cardiac cell growth but also have inherent conductive properties. Here, we present an injectable reverse thermal gel (RTG)-based cardiac cell scaffold system that is both biocompatible and conductive. Following the synthesis of a highly functionalizable, biomimetic RTG backbone, gold nanoparticles (AuNPs) were chemically conjugated to th

Targeted delivery of silver nanoparticles and alisertib: in vitro and in vivo synergistic effect against glioblastoma.

AIM: Targeted biocompatible nanoplatforms presenting multiple therapeutic functions have great potential for the treatment of cancer. MATERIALS & METHODS: Multifunctional nanocomposites formed by polymeric nanoparticles (PNPs) containing two cytotoxic agents - the drug alisertib and silver nanoparticles - were synthesized. These PNPs have been conjugated with a chlorotoxin, an active targeting 36-amino acid-long peptide that specifically binds to MMP-2, a receptor overexpressed by brain cancer cells. RESULTS: The individual and synergistic activity of these two cytotoxic agents against gliob

Synthetic hydrogel scaffold is an effective vehicle for delivery of INFUSE (rhBMP2) to critical-sized calvaria bone defects in rats.

Medtronic's INFUSE Bone Graft provides surgeons with a potent tool for stimulating bone formation. Current delivery vehicles that rely on Absorbable Collagen Sponges (ACS) require excessive quantities of the active ingredient in INFUSE, recombinant human Bone Morphogenic Protein-2 (rhBMP2), to achieve physiologically relevant concentrations of the growth factor, driving up the cost of the product and increasing the likelihood of undesirable side effects in neighboring tissues. We demonstrate that a simple light-mediated, thiol-ene chemistry can be used to create an effective polymer delivery v

Electrochemical DNA biosensor for the detection of DNA hybridization with the amplification of Au nanoparticles and CdS nanoparticles.

In this article, colloidal gold nanoparticles (Au NPs) and carboxyl group-functionalized CdS Nanoparticles (CdS NPs) were immobilized on the Au electrode surface to fabricate a novel electrochemical DNA biosensor. Both Au NPs and CdS NPs, well known to be good biocompatible and conductive materials, could provide larger surface area and sufficient amount of binding points for DNA immobilization. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) experiments were performed to follow the whole electrode fabrication process. DNA immobilization and hybridization were characte

Prions in dermatology.

Prion diseases are uncommon fatal neurodegenerative disorders that have gained scientific importance as a result of the emergence of new forms of these diseases in both animals and humans. Prions appear to be composed principally or entirely of abnormal isoforms of a host-encoded glycoprotein. There is substantial scientific evidence to support the notion that bovine spongiform encephalopathy ("mad cow disease") has affected humans. Recent studies have demonstrated that prions can adhere easily to metal surfaces, and normal sterilization procedures are not likely to completely inactivate them.

Stimulation of calvarial bone healing with human bone marrow stromal cells versus inhibition with adipose-tissue stromal cells on nanostructured β-TCP-collagen.

UNLABELLED: Bioactive functional scaffolds are essential for support of cell-based strategies to improve bone regeneration. Adipose-tissue-derived-stromal cells (ASC) are more accessible multipotent cells with faster proliferation than bone-marrow-derived-stromal-cells (BMSC) having potential to replace BMSC for therapeutic stimulation of bone-defect healing. Their osteogenic potential is, however, lower compared to BMSC, a deficit that may be overcome in growth factor-rich orthotopic bone defects with enhanced bone-conductive scaffolds. Objective of this study was to compare the therapeutic p

Device Insertion Versus Material: Drivers of Inflammation in Diabetes Device Interfaces.

BACKGROUND: Automated insulin delivery (AID) systems are limited by the short wear time of insulin infusion sets, which typically need repla … CONCLUSION: These findings underscore the importance of minimizing insertion trauma and selecting biocompatible materials to promote device-tissue integration, prolong wear time, and enhance AID system performance.

Synergistically enhanced aspirin loading and pH-triggered controlled release via a ZIF-L/ZIF-8 hierarchical coating on titanium.

To address the challenge of preventing peri-implantitis, the present study developed a pH-responsive drug delivery coating on titanium (Ti) implants for controlled aspirin release. A hierarchical metal-organic framework coating was constructed on alkali- and heat-treated titanium by sequentially synthesizing Zeolitic imidazolate framework-L (ZIF-L) and ZIF-8 (denoted AHTL8). Material characterization confirmed the successful fabrication of a hierarchical micro-nano structure, which significantly enhanced surface hydrophilicity. The AHTL8 system exhibited a remarkably high aspirin-loading capac

Microfluidic GelMA/Bone-Derived Extracellular Matrix Microgels for Enhanced Stem Cell-Based Bone Regeneration.

Critical-sized bone defects caused by trauma or surgery exceed the innate regenerative capacity of bone, posing significant clinical challenges. Tissue engineering strategies based on injectable hydrogels and mesenchymal stem cells (MSCs) offer promise due to their adaptability to irregular defects. However, most current systems lack modular regenerative architecture and hierarchical biochemical cues needed to mimic native bone microenvironments, thereby limiting regenerative efficacy. In this study, we engineered modular, cell-laden microgels composed of bone-derived decellularized extracellu

In situ Grown Curcumin-Loaded MOFs on SrCO3 Functionalized Scaffold for Enhanced Osteogenic Differentiation via Antioxidant and Anti-inflammatory Activities.

To address the challenges posed by excessive inflammatory responses and reactive oxygen species (ROS) in the complex microenvironment during pathological bone defect repair, this study developed a composite scaffold. First, zeolitic imidazolate framework-8 (ZIF-8) loaded with curcumin (CCM) was grown in situ on the surface of strontium carbonate (SrCO3) to form SrCO3@CZIF-8 composite particles with a core-shell structure. Subsequently, these particles were integrated into a poly-l-lactic acid (PLLA) matrix using selective laser sintering technology. Experimental results indicate that the CCM a

PURPOSE: To evaluate the inflammatory response, fibrotic encapsulation, tissue integration, and antibacterial effectiveness of silicone implants coated with decellularized bovine pericardium membranes, with or without vancomycin impregnation. METHODS: Seventy-two Wistar rats received subcutaneous silicone implants and were allocated to six groups: uncoated silicone under aseptic conditions; uncoated silicone under infected conditions; silicone coated with decellularized bovine pericardium under aseptic conditions; silicone coated with decellularized bovine pericardium under infected condition

Engineering injectable alginate hydrogels for mesenchymal stem cell delivery: comparative evaluation of ionic crosslinking strategies and earlyin vitrooutcomes.

Injectable hydrogels are widely investigated as carriers for mesenchymal stem cells (MSCs); however, the influence of ionic crosslinking strategy on injectability-relevant properties and earlyin vitrocell responses remains insufficiently defined from a design perspective. In this study, alginate-based hydrogels were prepared using three ionic crosslinking approaches-internal (CaCO3/ glucono-delta-lactone (GDL)), external (CaCl2), and combined gelation-and comparatively evaluated as delivery matrices for human adipose-derived MSCs. The hydrogels were characterized in terms of microstructural fe
