Abstract A direct‐current, cold‐atmospheric‐pressure air plasma microjet (PMJ) sustained in a quasi‐steady gas cavity liquid medium is used to inactivate Staphylococcus aureus ( S. ) suspended the liquid. The temperature and pH value of change steady‐state values about 40 °C 3.0–4.5, respectively, after 10 min treatment. decrease attributed reaction NO x produced with water at gas–liquid interface. concentrations are measured be 37 mg · L −1 21 , 20 Effective inactivation found start...
Nanohydroxyapatite (HA) synthesized by biomimetic strategy is a promising nanomaterial as bone substitute due to its physicochemical features similar those of natural nanocrystal in tissue. Inspired mussel adhesive chemistry, novel nano-HA was our work employing polydopamine (pDA) template under weak alkaline condition. Subsequently, the as-prepared pDA-templated HA (tHA) introduced into polycaprolactone (PCL) matrix via coelectrospinning, and bioactive tHA/PCL composite nanofiber scaffold...
Abstract Gelatin hydrogel with excellent biodegradability and biocompatibility is widely used in drug delivery, electronic devices, flexible sensors. However, it prone to dehydration, which severely restricts its applications. The incorporation of hydrated ions, for example choline chloride (ChCl), can not only improve water retention capacity but also keep biocompatibility. Unfortunately, the improvement realized at expense mechanical properties because ChCl suppress crystallization...
Magnesium calcium phosphate biocement (MCPB) with rapid-setting characteristics was fabricated by using the mixed powders of magnesium oxide (MgO) and dihydrogen (Ca(H 2 PO 4 ) ·H O). The results revealed that MCPB hardened after mixing water for about 7 min, compressive strength reached 43 MPa setting 1 h, indicating had a short time high initial mechanical strength. After acid–base reaction containing MgO Ca(H O in molar ratio : 1, final hydrated products were Mg 3 (PO Ca . degradable...
The design and development of functional biomimetic systems for programmed stem cell response is a field topical interest. To mimic bone extracellular matrix, we present an innovative strategy constructing drug-loaded composite nanofibrous scaffolds in this study, which could integrate multiple cues from calcium phosphate mineral, bioactive molecule, highly ordered fiber topography the control fate. Briefly, inspired by mussel adhesion mechanism, polydopamine (pDA)-templated...
Fully bio-based ion-conductive organo-hydrogels with multi-functionalities such as high mechanical properties, self-healing, anti-freezing, and non-drying capabilities are still extremely rare so far, achieving it remains a great challenge. In this work, starch/natural rubber composite hydrogel is first obtained by simple one-pot method, then an organo-hydrogel composed of starch, natural rubber, lithium chloride, glycerol adjustable properties (ultimate tensile stress 0.15-2.33 MPa failure...
Gelatin hydrogels, a kind of ideal biobased material with excellent biodegradability and biocompatibility, are weak easy to dehydrate in an ambient environment, which greatly hinders their practical application. In this study, we have developed simple strategy fabricate robust, nondrying, elastic gelatin hydrogels through introducing choline chloride (ChCl) hydrogel networks. Benefiting from the hydrated ions ChCl, water content can be simply controlled by adjusting amount ChCl; as result,...
For the first time we observed well-resolved Ca(i) and Ca(ii) signal changes in fluorohydroxyapatites with different fluorine contents by solid state NMR. The experiment results show that ions perturb chemical environment of OH- more than phosphorus tetrahedra ions.
Abstract Bio‐scaffolds designed to mimic endogenous niches have been used extensively in stem cell therapy and tissue regeneration. However, limited entry of nutrients cells inside the scaffold can lead poor survival proliferation, implantation require an invasive surgical approach. Here, a noninvasive method using injectable 3D porous micro‐scaffolds with bio‐engine is developed for transplantation A liquid nitrogen flash‐frozen immediately smashed prepare nanocarriers‐alginate composite...

Bone implants of polyetheretherketone (PEEK) have become increasingly popular in the orthopedic field but its bioinertness and poor osteogenic properties significantly limit applications for bone regeneration osseointegration with host bone. In this study, by incorporation mesoporous diopside (MD) into PEEK matrix, macro-mesoporous PEEK/MD (PM) composites as interconnected macropores 300-400 μm were fabricated using method cold press-sintering salt-leaching. The results showed that...
