The need to recover the graphene properties in terms of electrical and thermal conductivity calls for application reduction processes leading removal oxygen atoms from oxide sheet surface. recombination carbon–carbon double bonds causes a partial recovery original mainly limited by presence residual lattice defects. However, loss polar oxygen-based functional groups renders material dispersibility rather complicated. In addition, oxygen-containing are reaction sites useful further bind...
Inspired by mussel bioadhesion in nature, dopamine is extensively used for biomaterial surface modification. In this study, we coated on demineralized enamel and dentin surfaces to evaluate the effect of polydopamine coating dental remineralization. Dental slices containing were first etched with 37% phosphoric acid 2 min, followed immersion a mg/mL freshly prepared solution (10 mM Tris buffer, pH 8.5) approximately 24 h at room temperature dark obtain coating. Then, without immersed...
The research on complicated kinomics and kinase-target drug discovery requires the development of simple, cost-effective, multiplex kinase assays. Herein, we propose a novel versatile biosensing platform for detection protein activity based graphene oxide (GO)-peptide nanocomplex phosphorylation-induced suppression carboxypeptidase Y (CPY) cleavage. Kinase-catalyzed phosphorylation protects fluorophore-labeled peptide probe against CPY digestion induces formation GO/peptide resulting in...
Effective bone tissue engineering is important to overcome the unmet clinical challenges as more than 1.6 million grafts are done annually in United States. Successful needs minimally three critical constituents: osteoprogenitor cells, osteogenic factors, and osteoinductive/osteoconductive scaffolds. Osteogenic progenitors derived from multipotent mesenchymal stem cells (MSCs), which can be prepared numerous sources, including adipose tissue. We previously showed that BMP9 most BMP induces...
Carboxylated poly(vinyl alcohol) (PVA-COOH) is prepared by modifying PVA with succinic anhydride. Then, poly(hexamethylene guanidine (PHMG) as a cross-linker and gallic acid (GA) an antioxidant are added to obtain PVA-based composite hydrogel films (PVA-COOH-PHMG/GA). The as-prepared show hydrophilic surfaces, high swelling ratios of 600–700%, low water solubility for PVA-COOH-PHMG samples (about 10%), good mechanical properties. Importantly, when the initial bacterial concentration 107...
A safe and efficient nanocomposite hydrogel for colon cancer drug delivery was synthesized using pH-sensitive biocompatible graphene oxide (GO) containing azoaromatic crosslinks as well poly (vinyl alcohol) (PVA) (GO–N=N–GO/PVA composite hydrogels). Curcumin (CUR), an anti-cancer drug, encapsulated successfully into the through a freezing thawing process. Fourier transform infrared spectroscopy, scanning electron microscopy Raman spectroscopy were performed to confirm formation morphological...
Combined targeted drug delivery and sustained release, through the application of nanomedicine, show great potential in cancer therapy diagnostics. Systems based on folic acid conjugated with graphene oxide-based magnetic nanoparticles (NPs) distinct advantages for such chemotherapeutic applications. Herein, we prepared FA-Fe3O4@nGO-DOX (MNPs) a uniform size distribution nanoscale oxide (nGO) encapsulated Fe3O4, which was (FA) loaded doxorubicin (DOX). The MNPs were characterized by various...
ABSTRACT Objectives To investigate the prevalence and severity of external apical root resorption (EARR) volumetrically with clear aligner therapy using cone-beam computed tomography (CBCT) as well determine possible risk factors develop a prediction model for EARR. Materials Methods In this retrospective study, 320 incisors from 40 Class II patients treated aligners (Invisalign) were included in study. CBCT images obtained at pretreatment (T0) posttreatment (T1). Root volume was calculated...
Electrospinning was used to make activated carbon nanofibers with polyacrylonitrile (PAN) as the precursor. The applied voltage found be more influential on electrospun PAN fiber diameters than flow rate and needle tip-collector distance. Tensile load tear strength of membranes increased thickness, accompanied a decrease in air permeability; however, burst not significantly influenced by thickness. Electrospun nanofiber were stabilized then at 800°C KOH activating agent nanofibers....
Chain-extended poly(lactic acid) /clay nanocomposites were prepared through extrusion process. The effects of the content and dispersion morphology clay on molecular weight distribution rheological behavior chain extended discussed. extender/clay ratio would strongly affect gelation degree acid), thus affecting melt strength elasticity. increased with increasing content, reaching a maximum value, after which it decreased. Then foamed supercritical CO 2 , cellular structure, cell size,...
Abstract Polylactic‐co‐glycolic acid (PLGA) is one of the most promising synthetic materials for tissue engineering due to its excellent biocompatibility, good mechanical properties, and tunable biodegradation time. However, accumulation PLGA degradative products could cause significant host inflammatory response, a microenvironment favoring fibrosis that mainly mediated by M1 subtype macrophage. Drug loading an emerging technology modify electrospun nanofibers, asiaticoside (AS) was...
Epoxy-based chain extended high-melt-strength poly (lactic acid) (PLA) was prepared. Rheological properties and the thermal behaviours of PLA were studied. The rheological indicated that melt elasticity strength samples gradually improved by increasing content extender (CE). Moreover, results showed crystallinity spheruilite morphology greatly influenced due to introduction CE. effect CE contents on foam also Adding resulted in higher expansion ratio smaller cell size foams.
Bone tissue engineering has emerged as a promising restorative strategy for bone reconstruction and defect repair.

We report a facile means to engineer oriented surface topology of poly(ε-caprolactone) (PCL) via homoepitaxial crystallization. It involved uniaxially stretching the PCL substrate, immersing uniaxial substrate in nutrient solution that could dissolve small amount solute and meanwhile ensure integrity as well evaporating solvent. Morphology observations demonstrated uniform edge-on lamellae were aligned parallelly on where orientation epitaxial strongly correlated with strain substrate. By...
