The development of biosafe nanoplatforms with diagnostic and therapeutic multifunction is extremely demanded for designing cancer theranostic medicines. Here, a facile methodology is developed to construct a multifunctional nanotheranostic that gathers five functions, upconversion luminescence (UCL) imaging, T1-weighted magnetic resonance imaging (MRI),(More)
Because magnetic resonance imaging (MRI) contrast agents play a vital role in diagnosing diseases, demand for new MRI contrast agents, with an enhanced sensitivity and advanced functionalities, is very high. During the past decade, various inorganic nanoparticles have been used as MRI contrast agents due to their unique properties, such as large surface(More)
An ultrasmall hydrodynamic diameter is a critical factor for the renal clearance of nanoparticles from the body within a reasonable timescale. However, the integration of diagnostic and therapeutic components into a single ultrasmall nanoparticle remains challenging. In this study, pH-activated nanodots (termed Fe-CPNDs) composed of coordination polymers(More)
Here, a two-step method has been developed for synthesizing carboxy-terminated NaYF(4): Yb(3+), Er(3+)@SiO(2) core@shell nanoparticles (UCNP@SiO(2)) with ultrathin shell (1.5 nm). First, the NaYF(4): Yb(3+), Er(3+) upconverting nanoparticles (UCNPs) were prepared using solvothermal technology; then, silica shells (SiO(2)) were deposited on the nanocrystals(More)
Herein, a three-dimensional carbohydrate modified polyacrylamide hydrogel microarray (3D carbohydrate hydrogel microarray) has been fabricated and employed as micro-reactor for capturing Escherichia coli (E. coli) by multivalent binding of concanavalin A (Con A) with O-antigen on the cellular surface of E. coli and immobilized monosaccharides on hydrogel(More)
Hydrophobic ultrasmall nanoparticles synthesized in nonpolar solvents exhibit great potential in biomedical applications. However, a major challenge when applying these nanomaterials in biomedical research is the lack of a versatile strategy to render them water dispersible while preserving the hydrodynamic diameter (HD) to be less than 8 nm for efficient(More)
A novel 4,4'-bipyridine linked dinuclear copper(II) complex, [Cu2L2(bipy)](NO3)2·bipy (L = 2-[2-(2-hydroxyethylamino) ethylimino]methyl-6-methylphenol; bipy = 4,4'-bipyridine), was prepared and characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction. The Cu···Cu distance is 11.129(2) Å. The CuII atom is coordinated by one(More)
The effective delivery of bioimaging probes to a selected cancerous tissue has extensive significance for biological studies and clinical investigations. Herein, the peptide functionalized NaGdF4 nanodots (termed as, pPeptide-NaGdF4 nanodots) have been prepared for highly efficient magnetic resonance imaging (MRI) of tumor by formation of Gd-phosphonate(More)
BACKGROUND This retrospective study aims to investigate the efficacy and safety of a combined posterior lateral and anteromedial approach in the treatment of terrible triad of the elbow (TTE). METHODS TTE patients who received a combination of posterior lateral and anteromedial approach or other conservative treatments were included in the present study.(More)
