[PMID: 37607447 DOI: 10.1016/j.bios.2023.115613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 08/06/2023] [Accepted: 08/17/2023] [Indexed: 08/24/2023]
Abstract
We present a novel dual-mode DNA-walker based optical fiber biosensor (DMDW-Opt biosensor) for sensitive assay of micro-RNAs in bio-samples. In the sensor system, we develop a new strategy for the cascade amplification, DNA-walker/rolling cycle amplification (RCA), by the use of the residue track of the walker. The strategy can significantly improve the response of the sensor and avoid any tedious operation procedure. Dual-mode readouts, i.e., fluorescence and chemiluminescence, are measured independently without interfering with each other to achieve reliable and accurate analysis. Optical fibers with the surface modified by gold nanoparticles are utilized as the support for fabrication of the sensor, which would be benefit for developing miniaturized and portable sensing devices. The performance of the proposed method is evaluated by using micro-RNAs (MiR-155 and MiR-21) as the analytical target. The method is successfully applied for accurate determination of micoRNAs in human serum and MCF-7 cells. Our method can perform sensitive assays of MiR-155 with limit-of-detection as low as 97.72 fM and 11.22 fM, MiR-21 with limit-of-detection as low as 107.15 fM and 8.32 fM for the fluorescence- and the chemiluminescence-readout respectively, and the biosensor exhibits excellent specificity, reproducibility and storage stability, indicating its valuable potential applications for sensing trace-amount targets in complicated real samples.

Abstract
Early detection and diagnosis of many cancers is very challenging. Late stage detection of a cancer always leads to high mortality rates. It is imperative to develop novel and more sensitive and effective diagnosis and therapeutic methods for cancer treatments. The development of new cancer treatments has become a crucial aspect of medical advancements. Nanobots, as one of the most promising applications of nanomedicines, are at the forefront of multidisciplinary research. With the progress of nanotechnology, nanobots enable the assembly and deployment of functional molecular/nanosized machines and are increasingly being utilized in cancer diagnosis and therapeutic treatment. In recent years, various practical applications of nanobots for cancer treatments have transitioned from theory to practice, from in vitro experiments to in vivo applications. In this paper, we review and analyze the recent advancements of nanobots in cancer treatments, with a particular emphasis on their key fundamental features and their applications in drug delivery, tumor sensing and diagnosis, targeted therapy, minimally invasive surgery, and other comprehensive treatments. At the same time, we discuss the challenges and the potential research opportunities for nanobots in revolutionizing cancer treatments. In the future, medical nanobots are expected to become more sophisticated and capable of performing multiple medical functions and tasks, ultimately becoming true nanosubmarines in the bloodstream.

Abstract
Seeman's pioneer idea has led to the foundation of DNA nanostructures, resulting in a remarkable advancement in DNA nanotechnology. Over the last few decades, remarkable advances in drug delivery techniques have resulted in the self-assembly of DNA for encapsulating candidate drug molecules. The nuclear targeting capability of DNA nanostructures is lies within their high spatial addressability and tremendous potential for active targeting. However, effective programming and assembling those DNA molecules remains a challenge, making the path to DNA nanostructures for real-world applications difficult. Because of their small size, most nanostructures are self-capable of infiltrating into the tumor cellular environment. Furthermore, to enable controlled and site-specific delivery of encapsulated drug molecules, DNA nanostructures are functionalized with special moieties that allow them to bind specific targets and release cargo only at targeted sites rather than non-specific sites, resulting in the prevention/limitation of cellular toxicity. In light of this, the current review seeks to shed light on the versatility of the DNA molecule as a targeting and encapsulating moiety for active drugs in order to achieve controlled and specific drug release with spatial and temporal precision. Furthermore, this review focused on the challenges associated with the construction of DNA nanostructures as well as the most recent advances in the functionalization of DNA nanostructures using various materials for controlled and targeted delivery of medications for cancer therapy.

Abstract
Nanotechnology and stem cells are one of the most promising strategies for clinical medicine applications. The article provides an up-to-date view on advances in the field of regenerative and targeted vascular therapies describing a molecular design (propulsion mechanism, composition, target identification) and applications of nanorobots. Stem cell paragraph presents current clinical application of various cell types involved in vascular biology including mesenchymal stem cells, very small embryonic-like stem cells, induced pluripotent stem cells, mononuclear stem cells, amniotic fluid-derived stem cells and endothelial progenitor cells.

Abstract
During the preparation of single-stranded DNA catenanes, topological isomers of different linking numbers (Lk) are intrinsically produced, and they must be separated from each other to construct sophisticated nanostructures accurately. In many previous studies, however, mixtures of these isomers were directly employed to construct nanostructures without sufficient characterization. Here, we present a method that easily and clearly characterizes the isomers by polyacrylamide gel electrophoresis. To the mixtures of topological isomers of [2]catenanes, two-strut oligonucleotides, which are complementary with a part of both rings, were added to connect the rings and fix the whole conformations of isomers. As a result, the order of migration rate was always Lk3 > Lk2 > Lk1, irrespective of gel concentration. Thus, all the topological isomers were unanimously characterized by only one polyacrylamide gel electrophoresis experiment. Well-characterized DNA catenanes are obtainable by this two-strut strategy, opening the way to more advanced nanotechnology.

Abstract
DNA nanorobots have emerged as new tools for nanomedicine with the potential to ameliorate the delivery and anticancer efficacy of various drugs. DNA nanostructures have been considered one of the most promising nanocarriers. In the present study, we report a DNA framework-based intelligent DNA nanorobot for selective lysosomal degradation of tumor-specific proteins on cancer cells. We site-specifically anchored an anti-HER2 aptamer (HApt) on a tetrahedral framework nucleic acid (tFNA). This DNA nanorobot (HApt-tFNA) could target HER2-positive breast cancer cells and specifically induce the lysosomal degradation of the membrane protein HER2. An injection of the DNA nanorobot into a mouse model revealed that the presence of tFNA enhanced the stability and prolonged the blood circulation time of HApt, and HApt-tFNA could therefore drive HER2 into lysosomal degradation with a higher efficiency. The formation of the HER2-HApt-tFNA complexes resulted in the HER2-mediated endocytosis and digestion in lysosomes, which effectively reduced the amount of HER2 on the cell surfaces. An increased HER2 digestion through HApt-tFNA further induced cell apoptosis and arrested cell growth. Hence, this novel DNA nanorobot sheds new light on targeted protein degradation for precision breast cancer therapy.

Abstract
Despite decades of effort, gene therapy (GT) has failed to deliver clinically significant anticancer treatment, owing in part to low selectivity, low efficiency, and poor accessibility of folded RNA targets. Herein, we propose to solve these common problems of GT agents by using a DNA nanotechnology approach. We designed a deoxyribozyme-based DNA machine that can i) recognize the sequence of a cancer biomarker with high selectivity, ii) tightly bind a structured fragment of a housekeeping gene mRNA, and iii) cleave it with efficiency greater than that of a traditional DZ-based cleaving agent. An important advantage of the DNA nanomachine over other gene therapy approaches (antisense, siRNA, and CRISPR/cas) is its ability to cleave a housekeeping gene mRNA after being activated by a cancer marker RNA, which can potentially increase the efficiency of anticancer gene therapy. The DNA machine could become a prototype platform for a new type of anticancer GT agent.
