This study reports an Fe(3+)-functionalized carbon quantum dots (Fe(3+)-functionalized CQDs) for the highly sensitive and selective detection of ascorbic acid (AA) in rat brain microdialysates based on the specific redox reaction between iron(III) ions and AA. The carbon quantum dots (CQDs) were synthesized by one-step pyrolysis of a small organic molecules(More)
Hydroxyl radical (•OH) is an important marker of the progress of heavy metal induced oxidative stress. However, most reported probes and detection methods cannot meet the need of monitoring the •OH concentration within the whole progress because of the limited linear range. Besides, a low detection limit, high sensitivity, and good selectivity were also(More)
Multifunctional nanomaterials for cancer diagnosis and therapy have recently prompted widespread concern. To avoid nanotoxicity, the development of novel degradable functional materials must be our main focus. In this study, we firstly developed ethylenediaminetetraacetic acid calcium disodium salt (EDTA)- and bovine serum albumin (BSA)-capped Mn3O4(More)
Lanthanide-based contrast agents have attracted increasing attention for their unique properties and potential applications in cancer theranostics. To date, many of these agents have been studied extensively in cells and small animal models. However, performance of these theranostic nanoparticles requires further improvement. In this study, a novel(More)
Photothermal treatment, a new approach for inactivation of bacteria and pathogens that does not depend on traditional therapeutic approaches, has recently received much attention. In this study, a new type of nanoplatform (PDA@Fe3O4 + PES) was fabricated by using polydopamine (PDA, a photothermal conversion agent) to encapsulate Fe3O4 (a magnetic(More)
The aim of the study was to compare the efficacy and safety between high-intensity focused ultrasound (HIFU) treatment and uterine artery embolization (UAE) treatment; we retrospectively analyzed 152 cases with cesarean scar pregnancy (CSP). Based on our inclusion and exclusion criteria, 152 patients (average age, 31.8 ± 4.6 years old) with CSP were(More)
