Cell-laden hydrogels are widely used in tissue engineering and regenerative medicine. However, many of these not optimized for use the oral environment, where they exposed to blood saliva. To address challenges, we engineered an alginate-based adhesive, photocrosslinkable, osteoconductive hydrogel biomaterial (AdhHG) with tunable mechanical properties. The was as injectable mesenchymal stem cell (MSC) delivery vehicle craniofacial bone applications. Subcutaneous implantation mice confirmed...
We present a microfluidic platform for the synthesis of monodisperse chitosan based nanoparticles via self-assembly at physiological pH. The resultant are shown to encapsulate hydrophobic anticancer drugs while providing sustainable release profile with high tunability.
Periodontitis is a common chronic inflammatory disease that affects tooth-supporting tissues. We engineer multifunctional periodontal membrane for the guided tissue regeneration of lost The major drawback current membranes lack properties. Here, series nanofibrous based on poly(ε-caprolactone) with tunable biochemical and biophysical properties were developed regeneration. engineered surface coated using biomimetic polydopamine to promote adhesion therapeutic proteins cells. demonstrate...
The use of solvent‐free microfluidics to fine‐tune the physical and chemical properties chitosan nanoparticles for drug delivery is demonstrated. Nanoparticle self‐assembly driven by pH changes in a water environment, which increases biocompatibility avoiding organic solvent contamination common with traditional techniques. Controlling time mixing (2.5–75 ms) during nanoparticle enables us adjust size surface potential order maximize cellular uptake, turn dramatically effectiveness. compact...
Alginate is a biopolymer with favorable pH-sensitive properties for oral delivery of peptides and proteins. However, conventional alginate nanogels have limitations such as low encapsulation efficiency because drug leaching during bead preparation burst release in high pH values. These shortcomings originate from large pore size the nanogels. In this work, we proposed an on-chip hydrodynamic flow focusing approach synthesis adjustable to achieve fine-tunable profile encapsulated bioactive...
Abstract Intramyocardial injection of hydrogels offers great potential for treating myocardial infarction (MI) in a minimally invasive manner. However, traditional bulk generally lack microporous structures to support rapid tissue ingrowth and biochemical signals prevent fibrotic remodeling toward heart failure. To address such challenges, novel drug‐releasing annealed particle (drugMAP) system is developed by encapsulating hydrophobic drug‐loaded nanoparticles into microgel building blocks...
A microfluidic platform is developed for the synthesis of monodisperse, 100 nm, chitosan based nanoparticles using nanogelation with ATP. The resulting tuned and enhanced transport electrochemical properties Nafion nanocomposite membranes, which highly favorable fuel cell applications.
A microfluidics approach to synthesize core-shell nanocarriers with high pH tunability is described. The sacrificial shell protects the core layer drugs and prevents their release in severe conditions of gastrointestinal tract, while allowing for drug proximity a tumor. proposed nanoparticulate drug-delivery system designed oral administration cancer therapeutics.
Montmorillonite nanolayers were treated with chitosan sulfate, as a functional biocompatibilizer, and then exfoliated in matrix to design nanohybrid membranes for potential wound dressing applications enhanced physical, mechanical antibacterial properties.
Serotonin-based nanoparticles represent a class of previously unexplored multifunctional nanoplatforms with potential biomedical applications. Serotonin, under basic conditions, self-assembles into monodisperse via autoxidation serotonin monomers. To demonstrate applications polyserotonin for cancer therapeutics, we show that these particles are biocompatible, exhibit photothermal effects when exposed to near-infrared radiation, and load the chemotherapeutic drug doxorubicin, releasing it...
Periodontal disease begins as an inflammatory response to a bacterial biofilm deposited around the teeth, which over time leads destruction of tooth-supporting structures and consequently tooth loss. Conventional treatment strategies show limited efficacy in promoting regeneration damaged periodontal tissues. Here, delivery platform is developed for small extracellular vesicles (sEVs) derived from gingival mesenchymal stem cells (GMSCs) treat periodontitis. EVs can achieve comparable...
Poly(ether ether ketone) (PEEK) was sulfonated at various degrees with sulfuric acid and dissolved in N, N-dimethylacetamide (DMAc). Montmorillonite (MMT) clay mixed this solution solvent-casted on a glass plate. A Fourier transfer infrared (FTIR) experiment of samples showed O−H vibration 3490 cm −1 SO peaks 1085 1100−1300 −1. Thermogravimetry analyzer (TGA) experiments revealed thermal degradation above 240 °C. X-ray diffraction (XRD) confirmed almost zero crystallinity for PEEK/MMT. When...
Abstract In the present study, a series of bioresource polyelectrolytes based on chitosan were synthesized and assessed for applicability in direct methanol fuel cells (DMFCs). A binary cross‐linking agent (sulfosuccinic acid/glutaraldehyde) was used structural modification membranes comprising various amounts sulfosuccinic acid (0, 8, 12, 16 wt% SSA/wt chitosan) prepared. It found that by increasing sulfonate groups' content up to wt%, proton conductivity permeability properties reach...
