Abstract While photoluminescence printing is a widely applied anticounterfeiting technique, there are still challenges in developing new generation materials with high security. Here we report the construction of photoresponsive supramolecular coordination polyelectrolyte (SCP) through hierarchical self-assembly lanthanide ion, bis-ligand and diarylethene unit, driven by metal-ligand ionic interaction. Owing to conformation-dependent photochromic fluorescence resonance energy transfer...
Photoinduced electron transfer (PET) is one of the most important mechanisms for developing fluorescent probes and biosensors. Quantitative prediction quantum yields these sensors crucial to accelerate rational development novel PET-based functional materials. Herein, we developed a general descriptor (ΔE) predicting yield PET probes, with threshold value ∼0.6 eV. When ΔE < eV, low (mostly <2%) due substantial activation in polar environments; when > high because inhibition PET. This simple...
Viscosity in the intracellular microenvironment shows a significant difference various organelles and is closely related to cellular processes. Such microviscosity live cells often mapped quantified with fluorescent molecular rotors. To enable rational design of viscosity-sensitive rotors, it critical understand their working mechanisms.

Furthermore, sensitively selectively detect infection, not only vitro but using an vivo keratitis mouse model....
Neuroinflammation and the NACHT, LRR, PYD domains-containing protein 3 inflammasome play crucial roles in secondary tissue damage following an initial insult patients with traumatic brain injury (TBI). Maraviroc, a C-C chemokine receptor type 5 antagonist, has been viewed as new therapeutic strategy for many neuroinflammatory diseases. We studied effect of maraviroc on TBI-induced neuroinflammation. A moderate-TBI mouse model was subjected to controlled cortical impact device. Maraviroc or...
Abstract Macrophages play crucial roles in protecting our bodies from infection and cancers. As macrophages are multi-functional immune cells, they have diverse plastic subsets, such as M1 M2, derived naïve M0 cells. Subset-specific macrophage probes essential for deciphering monitoring the various activation of macrophages, but developing has been challenging. Here we report a fluorescent probe, CDr17, which is selective over M2 or M0. The staining mechanism CDr17 explicated Gating-Oriented...
Rationale: Neuroinflammation is a primary feature of Alzheimer's disease (AD), for which an increasing number drugs have been specifically developed. The present study aimed to define the therapeutic impact specific subpopulation T cells that can suppress excessive inflammation in various immune and inflammatory disorders, namely, CD4+CD25+Foxp3+ regulatory (Tregs). Methods: To generate Aβ antigen-specific Tregs (Aβ+ Tregs), 1-42 peptide was applied vivo subsequent vitro splenocyte culture....
Abstract Inorganic boric acid (BA) is generally not considered an efficient afterglow material, and several groups have reported its extremely weak room‐temperature phosphorescence (RTP) in the blue spectral region. It discovered that heat treatment of BA results increased intensity (27‐fold increase) prolonged emission lifetime (from 0.83 to 1.59 s), attributed enhanced through‐space conjugation (TSC) BA. The can be further (≈415 folds) by introducing p‐hydroxybenzoic (PHA), which contains...
Tumor initiating cells (TIC) are resistant to conventional anticancer therapy and associated with metastasis relapse in cancer. Although various TIC markers their antibodies have been proposed, it is limited the use of for vivo imaging or treatment TIC. In this study, we discovered heme oxygenase 2 (HMOX2) as a novel biomarker developed selective small molecule probe TiNIR (tumor cell near infrared). detects enriches functionally active human lung tumors, through photoacoustic property, also...
Since anthrax spores are highly lethal to human beings and animals, also potential biological warfare agents, it is desirable develop simple, robust easy-device sensors that rapid sensitive, can selectively detect the Bacillus biomarker dipicolinic acid (DPA) quantitatively. Herein, we report a ratiometric luminescent "turn-on" sensor via mixing Eu3+ ions, sodium polyacrylate internal luminescence reference in water, which identify quantitatively with outstanding selectivity over aromatic...
Intracellular micro-temperature is closely related to cellular processes. Such local temperature inside cells can be measured by fluorescent thermometers, which are a series of materials that convert the information detectable fluorescence signals. To investigate intracellular fluctuation in various organelles, it essential develop site-specific organelle thermometers. In this study, we new Thermo Greens (TGs), visualize change almost all typical organelles. Through lifetime-based cell...
Mitochondrial inflammation triggered by abnormal mitochondrial division and regulated the Drp1/HK1/NLRP3 pathway is correlated with progression of aging-associated cognitive impairment (AACI). Alpinetin a novel flavonoid derived from Zingiberaceae that has many bioactivities such as antiinflammation anti-oxidation. However, whether alpinetin alleviates AACI suppressing pathway-inhibited still unknown. In present study, D-galactose (D-gal)-induced aging mice BV-2 cells were used, effects on...
