With the springing up of face synthesis techniques, it is prominent in need to develop powerful forgery detection methods due security concerns. Some existing attempt employ auxiliary frequency-aware information combined with CNN backbones discover forged clues. Due inadequate interaction image content, extracted frequency features are thus spatially irrelavant, struggling generalize well on increasingly realistic counterfeit types. To address this issue, we propose a Spatial-Frequency...

The use of cyclic perfluoroalkyl acids as anticorrosive agents in hydraulic fluids remains a poorly characterized source organofluorine compounds to the environment. Here, we investigated presence perfluoroethylenecyclohexanesulfonate (PFECHS) isomers environmental samples for first time using combination high resolution and tandem mass spectrometry. Five distinct peaks attributed different PFECHS perfluoropropylcyclopentanesulfonate (PFPCPeS) were identified samples. sum PFPCPeS displayed...
We report a new molecular design for optically triggered nm-scale translation of submolecular component relative to another.
We report here an ultrasensitive ratiometric fluorescent thermometer (RFT) based on the frustrated static excimers (FSEs) of DEH-PDI (<italic>N</italic>,<italic>N</italic>′-di(2-ethylhexyl)-3,4,9,10-perylenetetracarboxylic diimide) in physiological temperature range.
DNA-templated silver nanoclusters (DNA-AgNCs) have attracted significant attention due to their unique fluorescence properties. However, so far, the relatively low quantum yields of DNA-AgNCs and complex design DNA-AgNC-based sensors limited application in biosensing or bioimaging. Herein, we report a novel enhancement method. The β-Amyloid Oligomer (AβO) aptamer (AptAβO) with A10/T10 at its 3' end can be directly used as template fabricate AgNCs. When AgNCs were hybridized complementary...
To realize a real-time thermal feedback, monitoring the temperature of treated tissue is critical for photothermal therapy (PTT). The poor spatial resolution and low accuracy current methods detection limits application PTT. Herein, by assembling temperature-responsive DNA stem-loop marked with Texas red (TR) onto surface gold nanobipyramids (AuNBPs), bifunctional reagent (AuNBPs-DNA-TR) was fabricated PTT synchronously temperature. In this configuration, AuNBPs not only have high efficiency...
Detecting the temperature of intracellular mitochondria with high sensitivity and stability is crucial to understanding cellular metabolism revealing processes mitochondria-related physiology. In this paper, employing long fluorescence lifetime modified Au nanoclusters (mAuNCs) by 4-(carboxybutyl) triphenylphosphonium bromide, we developed a thermometer for mitochondria. A relative 2.8% excellent photostability were achieved from present thermometer. After incubation L929 cells, mAuNCs could...
3D facial landmark detection is extensively used in many research fields such as face registration, shape analysis, and recognition. Most existing methods involve traditional features models for the of landmarks, their performances are limited by hand-crafted intermediate process. In this paper, we propose a novel method, which directly locates coordinates landmarks from point cloud with well-customized graph convolutional network. The network learns geometric adaptively assistance...
A silicon nanowire-based fluorescence lifetime thermometer (NWFLT) was fabricated for the simultaneous measurement of intra- and extra-cellular temperatures.
Ionic calcium (Ca2+) is an important second messenger in cells, particularly the neuron. A deficiency or excess of Ca2+ would lead to neuronal apoptosis and further injury brain. For accurate analysis intracellular Ca2+, a single silicon nanowire (SiNW)-based ratiometric biosensor was constructed by simultaneously anchoring Ru(bpy)2(mcbpy-O-Su-ester)(PF6)2, as reference molecule, Fluo-3, response onto surface SiNW. The SiNW-based exhibits high sensitivity favorable selectivity for detecting...
Abstract The chains and segments of unordered cationic polypeptides are complex may produce unexpected biological activities. Herein, the Ugi's 4CC reaction is adopted to synthesize a alternating copolymer comprising ornithine glycine (poly(Orn‐alter‐Gly)) with an ordered sequence for enhanced bacterial resistance. In this technique, potassium isocyanate, 4‐(N‐carbobenzyloxyamino)‐1‐butyraldehyde 1‐(4‐Methoxyphenyl)ethylamine react MPE‐substituted poly(Orn‐alter‐Gly) in one step without...
Intracellular thermometry with favorable biocompatibility and precision is essential for insight into temperature-related cellular events. Here, liquid-core nanocapsule ratiometric fluorescent thermometers (LCN-RFTs) were prepared by encapsulating thermosensitive organic fluorophores (N,N'-di(2-ethylhexyl)-3,4,9,10-perylene tetracarboxylic diimide, DEH-PDI) hydrophobic solvent (2,2,4-trimethylpentane, TMP) polystyrene/silica hybrid nanoshells. As the unit of LCN-RFT, TMP solution DEH-PDI was...
