Abstract ：
A simple method for one-step synthesis of aggregated gold nanoparticles (a-AuNPs) using single-layer carbon dots (s-CDs) as the capping agents has been proposed. The obtained a-AuNPs are mainly composed of several spherical AuNPs of 20-25 nm sized, which aggregate to form nanogaps of similar to 1 nm. Furthermore, the obtained aAuNPs produce a strong localized surface plasmon resonance (LSPR) absorption band centered at around 640 nm, which is quite close to the wavelength of the commonly used 633 nm laser in surface enhanced Raman scattering (SERS). Thus, under the irradiation of 633 nm laser, a lot of electromagnetic field "hot spots" are formed at around the nanogaps, and strong SERS activity is achieved. The obtained a-AuNPs are dropped on tinfoil wafers to fabricate SERS substrates, which show the advantages of high sensitivity, fast response, good repeatability and satisfactory stability. On the basis, a sensitive SERS sensor is developed to detect malachite green in aquaculture water, with a low detection limit of 1 x 10(-9) mol/L.

Abstract ：
Combined the electrostatic interaction of the negatively charged gold nanorods (AuNRs) (as acceptor) and Ru(bpy)(3)(2+) (as donor), an electrochemiluminescence resonance energy transfer (ECL-RET) sensor was constructed and applied for the detection of organophosphorus pesticides (OPs). Negatively charged AuNRs were synthesized by modifying AuNRs with polystyrene sulfonate (PSS) firstly, which can bind to Ru(bpy)(3)(2+) through electrostatic interaction so that the luminophore was absorbed by the acceptor, the resonance energy transfer occurred and only low ECL signal had been detected. Thiocholine can be produced by the hydrolysis process of acetylthiocholine (ATCh) with the help of acetylcholinesterase (AChE), which can bond with PSS-modified AuNRs (PSS-AuNRs) through gold-sulfur interaction, this caused the releasing of the adsorbed Ru(bpy)(3)(2+) into the solution and resulting in the restoration of the ECL intensity. However, the activity of AChE was inhibited by OPs, and the recovery process of the ECL signal was thus suppressed as well. In this study, chlorpyrifos was chosen as model target, the results indicated that the correlation between the ECL intensity and the logarithm of chlorpyrifos concentration showed remarkable linearity across 1 ng/mL to 1 mg/mL, achieving a detection limit of 0.51 ng/mL. The proposed system has been utilized for detecting OPs in real samples with satisfied results.

Abstract ：
Acid vapors emitted by chemical industries pose an increasing threat to public health. The development of a costeffective sensor for the on-site and real-time monitoring of environmental acid vapor is of great significance. Aggregation-induced emission (AIE) luminogens overcome the aggregation-caused quenching effect and exhibit intense fluorescence when supported in the solid matrices. Silica isoporous membrane (SIM), characterized by vertically ordered nanochannels, holds great promise as a platform for encapsulating AIE luminogens and enabling gas sensing applications. The SIM containing surfactant micelles was prepared on an ITO electrode to obtain the M-SIM/ITO, and Tetrakis(4-carboxyphenyl)ethylene (TCPE) was employed as the investigated AIE luminogen. Upon application of positive potential, the negatively charged TCPE molecules were driven into the vertically ordered nanochannels, resulting in observable AIE fluorescence. By investigating the electrophoresis conditions such as TCPE charge, nanochannel microenvironment, and driving electric field, the AIE mechanism within the nanochannels was elucidated. The fluorescence of TCPE@M-SIM/ITO exhibited high sensitivity towards acid vapor and displayed reversible changes during the absorption and desorption processes. This behavior can be attributed to the SIM's strong absorption capability towards acid vapor as well as the reversible conversion of acid vapor on TCPE aggregates. This work presented an innovative methodology for studying luminophores within an orderly nanoconfined space, leading to a new perspective on the AIE mechanism.

Abstract ：
Metal-organic frameworks, which are the desired candidates for biosensing application due to their tunable properties, are significantly hindered by their rapid degradation in aqueous solutions, as well as the loss of their inherent fluorescence. Most studies aim to improve the hydrophobicity of materials by modifying their contact angle, thereby enhancing water stability. However, water droplets poorly adhere to the surface of hydrophobic materials, limiting their application for direct contact and detection in aqueous environments. Drawing inspiration from the sacrificial protection mechanism of butterfly wings used to evade predation and entanglement, a universal approach is successfully developed to protect water-sensitive MIL-MOFs from water molecule attack while preserving good hydrophilicity. Using the organic ligand 2,2 '-bipyridine-5,5 '-dicarboxylic acid (bpydc) as sacrificial protection scales, the MIL-125-NH2-bpydc demonstrated broad pH structural stability (pH 2-12) and fluorescence stability increased by 10.17 time in aqueous solutions, achieving the highest performance in MILMOFs. The MIL-125-NH2-bpydc is biocompatible enabling it to perform long-term fluorescence imaging in living cells and zebrafish, further detecting hydrogen sulfide (H2S) in the aqueous and biological systems via turn-on fluorescence emission. This study offers a novel and universal sacrifice-protection strategy for the design and development of the luminescent biocompatible MOFs tailored for biosensing applications.

Abstract ：
Real time detection of hydrogen sulfide (H2S) in deep brain regions is of great significance. Photoelectrochemical (PEC) biosensors hold promise for real-time monitoring but low sensitivity due to the use of small electrode restrained its application. In this study, a miniaturized sensor that integrates organic photoelectrochemical transistors (OPECTs) with optical fiber (OF) microelectrodes was designed for the first time, which can amplify the small PEC signal into large channel current change. A conductive gold layer and cuprous oxide nanoparticles (Cu2O NPs) were sequentially deposited onto the OF, followed by a Nafion polymer coating to enhance anti-interference capabilities. Cu2O reacts with H2S to generate Cu2S. The resulting Cu2O/Cu2S heterojunction induces changes in the PEC signal and channel current. Compared to a conventional PEC system, the OPECT sensor has higher sensitivity and lower detection limit, enabling monitoring of H2S concentration fluctuations within the rat brain, which demonstrates the approach's capability for highly sensitive in vivo biomarker detection.

Abstract ：
The intracellular delivery of protein drugs via nanocarriers offers significant potential for expanding their therapeutic applications. However, the unintended activation of innate immune responses and inflammation triggered by the carriers presents a major challenge, often compromising therapeutic efficacy. Here, we present oligoethylenimine-thioketal (OEI-TK), a reactive oxygen species-responsive cationic polymer with intrinsic anti-inflammatory properties, to overcome this challenge. OEI-TK self-assembles electrostatically with bovine serum albumin (BSA) to form stable nanoparticles (OTB NPs) with excellent encapsulation efficiency. In vitro studies confirmed that OTB NPs retained OEI-TK's antioxidant and anti-inflammatory properties, enhanced biocompatibility, and efficiently delivered BSA into cells. Furthermore, OEI-TK facilitated the intracellular delivery of beta-galactosidase while preserving its enzymatic activity, demonstrating its potential for functional protein transport. These findings highlight OEI-TK as a promising platform with dual benefits of inflammation modulation and intracellular protein delivery, holding potential for the synergistic treatment of inflammation-related diseases.

Abstract ：
Herein, a novel dual-function paper-based biosensor using diffusion wet area as readout has been developed for simple and sensitive detection of hyaluronidase (HAase) and human papillomavirus (HPV) 16 DNA, respectively. The target-regulated-water absorption hydrogel synthesized by hyaluronic acid (HA) and single-stranded DNA (ssDNA) is chosen as an ideal material for diffusion wet area generation on paper. The hydrogel can be degraded through the enzymolysis of HA by HAase or the trans-cleavage of ssDNA by HPV DNA-activated CRISPR/cas12a system. Then the diffusion wet area generated by the broken hydrogel with the free water released from the hydrogel dropped on the glass fiber filter paper can be captured by a smart-phone and calculated by the product of the pixel ratio (pixels of wet area/pixels of glass fiber filter paper) and actual area of the filter paper. The diffusion wet area has good linear relationships with HAase (0-40 U/mL) and HPV 16 DNA (0.1-1000 pM), respectively. The biosensor provides a novel signal readout mode, shows satisfactory sensitivity with the detection limits of 0.15 U/mL for HAase and 66.95 fM for HPV 16 DNA, and has been successfully used for HPV 16 DNA and HAase detection in clinical urine and cervical brush samples, which is promising for early cervical cancer screening and HPV monitoring in HPV patients.

Abstract ：
A highly efficient and sensitive non-enzymatic glucose sensor fabricated using NiO/NiPc composite nanomaterials was introduced by this study. The sensor employed a unique design by modifying the ITO electrode with the NiO/NiPc heterojunction. This enhancement was achieved by improving charge separation and transfer through the type-II heterojunction formed between NiO and NiPc. The integration of NiO/NiPc composite materials also improved the electrocatalytic activity. This enhancement was attributed to the increased concentration of oxygen vacancies, thereby boosting the overall performance of the sensor. The results of the sensor application demonstrated that under the optimized conditions (pH 4.0, -0.3 V bias), the sensor exhibited remarkable sensitivity and selectivity towards glucose, with a linear relationship between the photocurrent change and glucose concentration. The detection limit was as low as 0.016 nM, and the sensitivity was 4.146 mu A & sdot;mM- 1 & sdot;cm- 2. The sensor demonstrated excellent repeatability, stability, and high recovery rate in real sweat sample testing, highlighting its great potential for practical glucose detection applications.
