Abstract
The absolute quantification of miRNAs in a single cell allows to better understand the heterogeneity of cells and the relationship between miRNAs and diseases. However, seldom methods for miRNA quantification in a single cell have been reported because the miRNA content in a single cell is very low. Herein, an ultrasensitive chemiluminescence assay strategy based on rolling circle amplification (RCA) on a microchip platform was proposed for the absolute quantification of miRNAs in a single cell. In this strategy, a ring probe with specificity was designed and synthesized, which could perform RCA for target miRNAs to improve the sensitivity and satisfy the need of absolute quantification of miRNAs in a single cell. The 20 liver cancer cells (HepG2) and 20 normal liver cells (HL-7702) were analyzed using this method; it is found that the miRNA-21 contents varied among cells, and miRNA-21 was overexpressed in HepG2 cells. Compared with traditional methods, the proposed strategy has many advantages such as low cost, simple operation, short analysis time, good specificity, and lower probability of false positives. This method is expected to be one of the powerful tools for the absolute quantification of miRNAs in a single cell.

Abstract
The 10-nuclear heteroatom cluster modified {SbW8 O30 } was successfully synthesized and exhibited inhibitory activity (IC50 =0.29 μM). Based on proteomics analysis, Na4 Ni2 Sb2 W2 -SbW8 inhibited ATP production by affecting the expression of 16 related proteins, hindering metabolic functions in vivo and cell proliferation due to reactive oxygen species (ROS) stress. In particular, the low expression of FAD/FMN-binding redox enzymes (relative expression ratio of the experimental group to the control=0.43843) could be attributed to the redox mechanism of Na4 Ni2 Sb2 W2 -SbW8 , which was consistent with the effect of polyoxometalates (POMs) and FMN-binding proteins on ATP formation. An electrochemical study showed that Na4 Ni2 Sb2 W2 -SbW8 combined with FMN to form Na4 Ni2 Sb2 W2 -SbW8 -2FMN complex through a one-electron process of the W atoms. Na4 Ni2 Sb2 W2 -SbW8 acted as catalase and glutathione peroxidase to protect the cell from ROS stress, and the inhibition rates were 63.3 % at 1.77 μM of NADPH and 86.06 % at 10.62 μM of 2-hydroxyterephthalic acid. Overall, our results showed that POMs can be specific oxidative/antioxidant regulatory agents.

Abstract
Invading cancer cells extend cell protrusions, which guide cancer-cell migration and invasion, eventually leading to metastasis. The formation and activity of cell protrusions involve the localization of molecules and organelles at the cell front; however, it is challenging to precisely isolate these subcellular structures at the single-cell level for molecular analysis. Here, we describe a newly developed microfluidic platform capable of high-throughput isolation of cell protrusions at single-cell precision for profiling subcellular gene expression. Using this microfluidic platform, we demonstrate the efficient generation of uniform cell-protrusion arrays (more than 5000 cells with protrusions) for a series of cell types. We show precise isolation of cell protrusions with high purity at single-cell precision for subsequent RNA-Seq analysis, which was further validated by RT-qPCR and RNA FISH. Our highly controlled protrusion isolation method opens a new avenue for the study of subcellular functional mechanisms and signaling pathways in metastasis.

Abstract
With high binding affinity, porous structures, safety, green, programmability, etc., DNA hydrogels have gained increasing recognition in the environmental field, i.e., advanced treatment technology of water and analysis of specific pollutants. DNA hydrogels have been demonstrated as versatile potential adsorbents, immobilization carriers of bioactive molecules, catalysts, sensors, etc. Moreover, altering components or choosing appropriate functional DNA optimizes environment-oriented hydrogels. However, the lack of comprehensive information hinders the continued optimization. The principle used to fabricate the most suitable hydrogels in terms of the requirements is the focus of this Review. First, different fabrication strategies are introduced and the ideal characteristic for environmental applications is in focus. Subsequently, recent environmental applications and the development of diverse DNA hydrogels regarding their synthesis mechanism are summarized. Finally, the Review provides an insight into the remaining challenging and future perspectives in environmental applications.

Abstract
DNA has arisen as a promising building material for the construction of hydrogels owing to its unique properties such as designability and biocompatibility. All-DNA hydrogels with only DNA molecules may have limited applications; hence a composite DNA hydrogel with multifunctional moieties is highly desired to cater for specific applications. Herein, a multifunctional DNA hydrogel is created by incorporating DNA with silver nanoclusters (AgNCs), in which AgNCs render the hydrogel simultaneously with fluorescent and antibacterial functions. A circular DNA is rationally designed, which allows for the elongation of DNA chain via an enzymatic polymerization as well as the formation of AgNCs onto DNA scaffolds. The resultant hybrid DNA hydrogel not only shows distinctive morphology and mechanical properties, but also exhibits fluorescent and antibacterial functions. These characteristics, along with its biocompatibility, will allow the hydrogel to be suitable for a variety of potential biomedical applications such as tissue engineering, wound dressing, biosensing, and bioimaging.
