The construction of intelligent stimuli-responsive nanosystems can substantially improve the sensitivity/resolution/specificity of diagnostic imaging and enhance the therapeutic efficiency of chemotherapy for cancer treatment. This work reports on a generic construction strategy to achieve a multiple stimuli-responsive theranostic system for cancer simply… (More)
In this paper, a new nanostructured Au-TiO(2) particle was synthesised and employed for the construction of a label-free amperometric immunosensor for carcinoembryonic antigen (CEA) determination. The spherical Au-TiO(2) nanoparticles provided a good microenvironment for the immobilization of biomolecules, enhanced the surface coverage of protein, had large… (More)
The development of visual tumor theranostic nanoparticles has become a great challenge. In this study, d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) was conjugated to acid-sensitive cis-aconitic anhydride-modified doxorubicin (CAD) to obtain pH-sensitive anti-tumor prodrug nanoparticles (TCAD NPs) via self-assembling. Subsequently, the… (More)
Reagentless, sensitive and multiplexed analysis of gyrB and K-ras gene biomarkers is achieved based on the proximity changes of two different redox-tags to the electrode surface upon DNA hybridizations, and the presence of the two gene biomarkers also acts as inputs and activates the logic gate.
We present an ultrasensitive aptasensor for the electronic monitoring of proteins through a dual amplified strategy in this paper. The target protein thrombin is sandwiched between an electrode surface confined aptamer and an aptamer-enzyme-carbon nanotube bioconjugate. The analytical signal amplification is achieved by coupling the signal amplification… (More)
This study attempts to characterize the clinical features of various subtypes of juvenile idiopathic arthritis (JIA) and try to investigate the prognostic factors. Patients with JIA hospitalized in Nanjing Children Hospital during April 2005 to April 2010 were enrolled. Clinical manifestations and laboratory parameters were retrospectively reviewed. A total… (More)
A unique matrix metalloproteinase 2-targeted photosensitizer delivery platform was developed in this study for tumor-targeting imaging and photodynamic therapy. The model photosensitizer therapeutic agent chlorin e6 (Ce6) was first covalently conjugated with matrix metalloproteinase 2-cleavable polypeptide and then modified with polyethylene glycol via a… (More)
One-spot signal-on and simultaneous electronic detection of lysozyme and adenosine is achieved based on target-induced release of aptamers and back-filling hybridization of the resulting single stranded DNAs with redox-tags conjugated aptamers.
The construction of a reagentless, sensitive, disposable and multiplexed electronic sensing platform for one-spot simultaneous determination of biomolecules with significant difference in size (proteins and small molecules) is described. The sensing surface is fabricated by the hybridization of two types of redox-tags conjugated aptamers with the… (More)
