Abstract
Lung cancer is the deadliest kind of cancer in the world, and the hypoxic tumor microenvironment can significantly lower the sensitivity of chemotherapeutic drugs and limit the efficacy of different therapeutic approaches. In order to overcome these problems, we have designed a drug-loaded targeted DNA nanoflowers encoding AS1411 aptamer and encapsulating chemotherapeutic drug doxorubicin and oxygen-producing drug horseradish peroxidase (DOX/HRP-DFs). These nanoflowers can release drugs in response to acidic tumor microenvironment and alleviate tumor tissue hypoxia, enhancing the therapeutic effects of chemotherapy synergistic with sonodynamic therapy. Owing to the encoded drug-loading sequence, the doxorubicin loading rate of DNA nanoflowers reached 73.24 ± 3.45%, and the drug could be released quickly by disintegrating in an acidic environment. Furthermore, the AS1411 aptamer endowed DNA nanoflowers with exceptional tumor targeting properties, which increased the concentration of chemotherapeutic drug doxorubicin in tumor cells. It is noteworthy that both in vitro and in vivo experiments demonstrated DNA nanoflowers could considerably improve the hypoxia of tumor cells, which enabled the generation of sufficient reactive oxygen species in combination with ultrasound, significantly enhancing the therapeutic effect of sonodynamic therapy and evidently inhibiting tumor growth and metastasis. Overall, this DNA nanoflowers delivery system offers a promising approach for treating lung cancer.

Abstract
DNA-templated metallization has emerged as an efficient strategy for creating nanoscale-metal DNA hybrid structures with a desirable conformation and function. Despite the potential of DNA-metal hybrids, their use as combinatory therapeutic agents has rarely been examined. Herein, we present a simple approach for fabricating a multipurpose DNA superstructure that serves as an efficient photoimmunotherapy agent. Specifically, we adsorb and locally concentrate Au ions onto DNA superstructures through induced local reduction, resulting in the formation of Au nanoclusters. The mechanical and optical properties of these metallic nanoclusters can be rationally controlled by their conformations and metal ions. The resulting golden DNA superstructures (GDSs) exhibit significant photothermal effects that induce cancer cell apoptosis. When sequence-specific immunostimulatory effects of DNA are combined, GDSs provide a synergistic effect to eradicate cancer and inhibit metastasis, demonstrating potential as a combinatory therapeutic agent for tumor treatment. Altogether, the DNA superstructure-templated metal casting system offers promising materials for future biomedical applications.

Abstract
Barcoding of nano- and micro-particles allows distinguishing multiple targets at the same time within a complex mixture and is emerging as a powerful tool to increase the throughput of many assays. Fluorescent barcoding is one of the most used strategies, where microparticles are labeled with dyes and classified based on fluorescence color, intensity, or other features. Microparticles are ideal targets due to their relative ease of detection, manufacturing, and higher homogeneity. Barcoding is considerably more challenging in the case of nanoparticles (NPs), where their small size results in a lower signal and greater heterogeneity. This is a significant limitation since many bioassays require the use of nano-sized carriers. In this study, we introduce a machine-learning-assisted workflow to write, read, and classify barcoded PLGA-PEG NPs at a single-particle level. This procedure is based on the encapsulation of fluorescent markers without modifying their physicochemical properties (writing), the optimization of their confocal imaging (reading), and the implementation of a machine learning-based barcode reader (classification). We found nanoparticle heterogeneity as one of the main factors that challenges barcode separation, and that information extracted from the dyes' nanoscale confinement effects (such as Förster Resonance Energy Transfer, FRET) can aid barcode identification. Moreover, we provide a guide to reaching the optimal trade-off between the number of simultaneous barcodes and classification accuracy supporting the use of this workflow for a variety of bioassays.

Abstract
DNA nanoflowers (DNFs) are topological flower-like nanostructures based on ultralong-strand DNA and inorganic metal-ion frameworks. Because of their programmability, biocompatibility, and controllable assembly size for specific responses to molecular recognition stimuli, DNFs are powerful biosensing tools for detecting biomolecules. Here, we review the current state of DNF-based biosensing strategies for in vivo and in vitro detection, with a view of how the field has evolved towards molecular diagnostics. We also provide a detailed classification of DNF-based biosensing strategies and propose their future utility. Particularly as transduction elements, DNFs can accelerate biosensing engineering by signal amplification. Finally, we discuss the key challenges and further prospects of DNF-based biosensing technologies in developing applications of a broader scope.

Abstract
Rolling circle amplification (RCA) is a powerful tool for the construction of DNA nanomaterials such as hydrogels, high-performance scaffolds and DNA nanoflowers (DNFs), hybrid materials formed of DNA and magnesium pyrophosphate. Such DNA nanomaterials have great potential in therapeutics, imaging, protein immobilisation, and drug delivery, yet limited chemistry is available to expand their functionality. Here, we present orthogonal strategies to produce densely modified RCA products and DNFs. We provide methods to selectively modify the DNA component and/or the protein cargo of these materials, thereby greatly expanding the range of chemical functionalities available to these systems. We have used our methodology to construct DNFs bearing multiple surface aptamers and peptides capable of binding to cancer cells that overexpress the HER2 oncobiomarker, demonstrating their potential for diagnostic and therapeutic applications.

Abstract
A coronavirus disease (COVID-19) outbreak associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been spreading widely through person-to-person transmission. Various detection approaches have been developed involving quantitative polymerase chain reaction (qPCR) methods, CRISPR-based systems, and direct targeting of specific coronavirus proteins. However, there have only been a few reports on the detection of RNA-dependent RNA polymerase (RdRP), the primer-independent RNA-replicable protein produced by the RNA genes of coronavirus. Here, we introduce a novel diagnostic methodology for COVID-19 using the RNA-directed and de novo RNA replicable function of RdRP. We devised an RNA platform for RdRP-induced transcription (RPRIT) that includes an RNA template that can be directly transcribed by RdRP. By utilizing RPRIT, the presence of RdRP can be readily confirmed within 30 min using isothermal incubation without PCR. This RdRP detection method can provide a new route for rapid diagnosis of RNA virus-infected patients.

Abstract
Control of the release properties of drugs has been considered a key factor in the development of drug delivery systems (DDSs). However, drug delivery has limitations including cytotoxicity, low loading efficiency, and burst release. To overcome these challenges, nano or micro-particles have been suggested as carrier systems to deliver chemical drugs. Herein, nano-sized DNA particles (DNAp) were manufactured to deliver netropsin, which is known to bind to DNA minor grooves. The rationally designed particles with exposed rich minor grooves were prepared by DNAp synthesis via rolling circle amplification (RCA). DNAp could load large quantities of netropsin in its minor grooves. An analytical method was also developed for the quantification of netropsin binding to DNAp by UV–visible spectrometry. Moreover, controlled release of netropsin was achieved by forming a layer of Ca2+ on the DNAp (CaDNAp). As a proof of concept, the sustained release of netropsin by CaDNAp highlights the potential of the DNAp-based delivery approach.

Abstract
Barcode technology has a broad spectrum of applications including healthcare, food security, and environmental monitoring, due to its ability to encode large amounts of information. With the rapid development of modern molecular research, barcodes are utilized as a reporter with different molecular combinations to label many biomolecular targets, including genomic and metabolic elements, even with multiplex targeting. Along with the advancements in barcoded bioassay, the improvements of various designs of barcode components, encoding and decoding strategies, and their portable adoption are indispensable in satisfying multiple purposes, such as medical confirmation and point-of-care (POC) testing. This perspective briefly discusses the current direction and progress of barcodes development and provides a hypothesis for barcoded bioassay in the near future.

Abstract
Synergy represents a natural approach for high-efficiency recognition in biological systems. Inspired by the recognition mechanism of viral infection of mammalian cells, here we develop heterovalency magnetic DNA nanoclaws with octopus arms morphology for synergetic cell capture. We demonstrated that the rigid-flexible DNA nanoclaws can load multiple antibodies (Abs) targeting different epitopes for enhanced capture of cancer cells, especially significantly increasing the capture efficiency of MDA-MB-231 cells up to 82.3 ± 7.1%. We also employed DNA nanoclaws with the combined use of multiple Abs to capture circulating tumor cells from clinical samples with high efficiency and specificity. We expect that the DNA nanoclaws not only could play a key role in liquid biopsy, but also could be expanded, with more applications benefiting from their modularity and programmability to modify various functionalities in future.

Abstract
Circulating tumor cells (CTCs) are the cancer cells that circulate in the peripheral blood after escaping from the original or metastatic tumors. CTCs could be used as non-invasive source of clinical information in early diagnosis of cancer and evaluation of cancer development. In recent years, CTC research has become a hotspot field wherein many novel CTC detection technologies based on microfluidics have been developed. Great advances have been made that exhibit obvious technical advantages, but cannot yet satisfy the current clinical requirements. In this study, we review the main advances in isolation and detection methods of CTC based on microfluidics research over several years, propose five technical indicators for evaluating these methods, and explore the application prospects. We also discuss the concepts, issues, approaches, advantages, limitations, and challenges with an aim of stimulating a broader interest in developing microfluidics-based CTC detection technology.
