NIR-Induced Photoswitching Hybrid DNA Nanoconstruct-Based Drug Delivery System for Spatiotemporal Control of Stem Cell Fate. SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2025:e2409530. [PMID: 40007062 DOI: 10.1002/smll.202409530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/15/2024] [Revised: 01/20/2025] [Indexed: 02/27/2025]
Abstract
Precise spatiotemporal control of drug delivery is extremely valuable for regulating stem cell fate, particularly in stem cell differentiation. A novel near-infrared (NIR)-mediated spatiotemporal delivery system is reported combining photo-switchable arylazopyrazole (AAP)-containing DNA strands and upconversion nanoparticles (UCNPs). This nano-drug delivery system (NDDS) enables precise modulation of DNA duplex structures in response to NIR stimuli, overcoming the limitations of traditional UV-responsive systems. AAP derivatives with enhanced photoswitching efficiency (≈98%) and significantly improved cis-form stability are engineered. The successful delivery of curcumin, a neurogenic compound with an affinity for the minor groove of DNA, to human neural stem cells (NSCs) is achieved using UCNP-DNA-AAP constructs. Upon 980 nm NIR light exposure, UCNPs efficiently up-converted NIR to UV light, triggering AAP photoisomerization and DNA dissociation, thus releasing curcumin. This approach enabled efficient spatiotemporal control over NSC differentiation while facilitating neuroprotection. Immunofluorescence and gene expression analyses demonstrated enhanced neuronal mRNA levels and neurite outgrowth in treated cells. In short, the NIR-mediated photo-switchable NDDS offers a precise and innovative approach to control stem cell fate, enabling spatiotemporal regulation of cellular processes. This technology has significant potential applications in nanomedicine and neuroscience, where precise drug delivery is crucial for targeted neural interventions.

Chen Q, Chen S, Chen Z, Tang K, Zeng L, Sun W, Wu F, Chen J, Lan J. Nucleic acid-functionalized upconversion luminescence biosensor based on strand displacement-mediated signal amplification for the detection of trivalent chromium ions. Anal Chim Acta 2024; 1328:343161. [PMID: 39266193 DOI: 10.1016/j.aca.2024.343161] [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: 06/03/2024] [Revised: 08/21/2024] [Accepted: 08/26/2024] [Indexed: 09/14/2024]
Abstract
BACKGROUND Rapid industrial development has generated serious pollution, including the presence of toxic and harmful heavy metal ions. Among them, trivalent chromium ion (Cr3+) is a very important element that poses a threat to life and health in our industrial wastewater pollution. Thus, it is important to develop efficient fluorescence methods for Cr3+ detection. In this study, an upconversion luminescence biosensor for detecting Cr3+ was constructed based on a DNAzyme, strand displacement reaction (SDR), and DNA-functionalized upconversion nanoparticles (UCNPs). RESULTS The sulfonate-rich poly (sodium 4-styrene sulfonate) (PSS) was modified onto the surface of UCNPs, forming UCNPs@PSS. Then, NH2-Capture probe DNA (NH2-Cp) was further modified onto the UCNPs@PSS surface through sulfonylation, resulting in UCNPs@PSS@NH2-Cp. The DNAzyme activated by Cr3+ triggered the release of the primer probe (Pp), which initiated the SDR system cycle, thereby releasing a tetramethylrhodamine (TAMRA)-modified signal probe (TAMRA-Sp). Finally, UCNPs@PSS@NH2-Cp bound to TAMRA-Sp through complementary base pairing, causing UCNPs and TAMRA to approach each other. Because of the luminescence resonance energy transfer (LRET) mechanism, the upconversion luminescence (UCL) signal of the UCNPs was quenched by TAMRA, enabling the detection of Cr3+ by the change of I585/I545 ratio. This biosensor has good stability, selectivity, and sensitivity, with a linear range of 0.5-75 nM and a detection limit of 0.135 nM for Cr3+. SIGNIFICANCE AND NOVELTY Firstly, based on LRET between UCNPs and TAMRA, the quantitative analysis of Cr3+ is achieved through the changes of ratio fluorescence. Secondly, the specificity of the biosensor is improved by utilizing the specific recognition of DNA enzymes. Thirdly, the signal amplification technology of the SDR cycle greatly improves the sensitivity of biosensor. This biosensor will be useful for future environmental safety monitoring and biopsy of biological fluids.

Abstract
The G-quadruplex/heme complexes are special DNA-based artificial metalloenzymes with peroxidase-like activity and are widely used in biosensing and biocatalysis. However, their peroxidase-like activity is not satisfactory. Due to the high programmability and good stability of DNA, DNA as a scaffold material is promising for enhancing the activity of artificial metalloenzymes. In this work, an effective DNA nanotube-based peroxidase was constructed using a self-assembly strategy. To improve the activity of G-quadruplex/heme complexes, a new method for the construction of G-quadruplex/heme complex arrays was proposed in a simple and inexpensive way. By designing the toes of DNA nanotubes as G-quadruplexes, G-quadruplex arrays could be formed on pure DNA nanotubes, and then the G-quadruplex arrays bind to heme to form a nanotube-supported DNAzyme termed as DNTzyme. Agarose gel electrophoresis, circular dichroism, and fluorescence microscopy were used to characterize DNTzyme. What is more, because the loading of DNAzyme on DNA nanotubes can increase their biological stability, a hydrogen peroxide detection sensor was constructed using the enhanced enzymatic activity and excellent stability of DNTzyme. The sensor could accurately and efficiently detect peroxide and show enhanced fluorescence with a detection limit of 49 nM for H2O2 and 1.4 μM for TBHP, and a color development time of about 5 min. This sensor is expected to have applications in bio-detection, biocatalysis, and drug delivery.

Abstract
The strategy of enhancing molecular recognition by improving the binding affinity of drug molecules against targets has generated a lot of successful therapeutic applications. However, one critical consequence of such affinity improvement, generally called "on-target, off-tumor" toxicity, emerged as a major obstacle limiting their clinical usage. Herein, we provide a modular assembly strategy that affords affinity-tunable DNA nanostructures allowing for immobilizing multiple aptamers that bind to the example antigen of EpCAM with different affinities. We develop a theoretical model proving that the apparent affinity of aptamer assemblies to target cells varies with antigen density as well as aptamer valency. More importantly, we demonstrate experimentally that the theoretical model can be used to predict the least valency required for discrimination between EpCAMhigh and EpCAMlow cells in vitro and in vivo. We believe that our strategy will have broad applications in an engineering nucleic acid-based delivery platform for targeted and cell therapy.

Abstract
We report a versatile method for the incorporation of functional molecules into oligonucleotides carrying reactive groups by using a template-directed postsynthetic approach in the solution phase. For this purpose, we prepared oligonucleotides carrying an amino group on the backbone by using an acylic threoninol scaffold. The resulting oligonucleotides could be used to introduce almost any molecule carrying aldehyde, which can be, among other things, a metal-binding ligand or a fluorophore. In our study, we incorporated aldehyde-bearing phenanthroline, a metal-binding ligand, into oligonucleotides by template-directed reversible conjugation. We observed that the use of an abasic sugar site instead of a natural nucleobase in the template strand increased the yield of conjugation and induced selective incorporation of the phenanthroline. This method could lead progress in the development of probes for the recognition of abasic regions in duplex DNA. Moreover, template-directed formation of metal ligand-oligonucleotide conjugates might have potential applications in hybrid biocatalysis for enantioselective transformations.

Abstract
By harnessing the chirality of the DNA double helix, chemists have been able to obtain new, reliable, selective, and environmentally friendly biohybrid catalytic systems with tailor-made functions. Nonetheless, despite all the advances made throughout the years in the field of DNA-based asymmetric catalysis, many challenges still remain to be faced, in particular when it comes to designing a "universal" catalyst with broad reactivity and unprecedented selectivity. Rational design and rounds of selection have allowed us to approach this goal. We report here the development of a DNA/RNA hybrid catalytic system featuring a covalently attached bipyridine ligand, which exhibits unmatched levels of selectivity throughout the current DNA toolbox and opens new avenues in asymmetric catalysis.
