Abstract
The development of nucleic acid-based drugs holds great promise for therapeutic applications, but their effective delivery into cells is hindered by poor cellular membrane permeability and inherent instability. To overcome these challenges, delivery vehicles are required to protect and deliver nucleic acids efficiently. Silica nanoparticles (SiNPs) have emerged as promising nanovectors and recently bioregulators for gene delivery due to their unique advantages. In this review, a summary of recent advancements in the design of SiNPs for nucleic acid delivery and their applications is provided, mainly according to the specific type of nucleic acids. First, the structural characteristics and working mechanisms of various types of nucleic acids are introduced and classified according to their functions. Subsequently, for each nucleic acid type, the use of SiNPs for enhancing delivery performance and their biomedical applications are summarized. The tailored design of SiNPs for selected type of nucleic acid delivery will be highlighted considering the characteristics of nucleic acids. Lastly, the limitations in current research and personal perspectives on future directions in this field are presented. It is expected this opportune review will provide insights into a burgeoning research area for the development of next-generation SiNP-based nucleic acid delivery systems.

Abstract
Over the past decades, significant progress has been made in utilizing nucleic acids, including DNA and RNA molecules, for therapeutic purposes. For DNA molecules, although various DNA delivery systems have been established, viral vector systems are the go-to choice for large-scale commercial applications. However, viral systems have certain disadvantages such as immune response, limited payload capacity, insertional mutagenesis and pre-existing immunity. In contrast, nonviral systems are less immunogenic, not size limited, safer, and easier for manufacturing compared with viral systems. What's more, nonviral DNA vectors have demonstrated their capacity to mediate specific protein expression in vivo for diverse therapeutic objectives containing a wide range of diseases such as cancer, rare diseases, neurodegenerative diseases, and infectious diseases, yielding promising therapeutic outcomes. However, exogenous plasmid DNA is prone to degrade and has poor immunogenicity in vivo. Thus, various strategies have been developed: (i) designing novel plasmids with special structures, (ii) optimizing plasmid sequences for higher expression, and (iii) developing more efficient nonviral DNA delivery systems. Based on these strategies, many interesting clinical results have been reported. This Review discusses the development of DNA-based nonviral gene therapy, including novel plasmids, nonviral delivery systems, clinical advances, and prospects. These developments hold great potential for enhancing the efficacy and safety of nonviral gene therapy and expanding its applications in the treatment of various diseases.

Abstract
Cellular delivery of plasmid DNA (pDNA) specifically into dendritic cells (DCs) has provoked wide attention in various applications. However, delivery tools that achieve effective pDNA transfection in DCs are rare. Herein, we report that tetrasulphide bridged mesoporous organosilica nanoparticles (MONs) have enhanced pDNA transfection performance in DC cell lines compared to conventional mesoporous silica nanoparticles (MSNs). The mechanism of enhanced pDNA delivery efficacy is attributed to the glutathione (GSH) depletion capability of MONs. Reduction of initially high GSH levels in DCs further increases the mammalian target of rapamycin complex 1 (mTORc1) pathway activation, enhancing translation and protein expression. The mechanism was further validated by showing that the increased transfection efficiency was apparent in high GSH cell lines but not in low GSH ones. Our findings may provide a new design principle of nano delivery systems where the pDNA delivery to DCs is important.

Abstract
In this study, peptide-gold nanoclusters with tunable fluorescence were prepared by a simple "one-pot" method, which were used for gene localization and delivery in vivo to achieve efficient intracellular colocalization, uptake, and transfection. The efficiency of pDNA transfection was up to 70.6%, and there was no obvious cytotoxicity. This study proves that the simple-composition and bio-friendly peptide-gold nanoclusters are promising gene delivery carriers and can provide a powerful theoretical and experimental basis for the application of peptide-metal nanocomplexes in gene delivery and other biomedicine fields.

Abstract
Cellular delivery of DNA using silica nanoparticles has attracted great attention. Typically, polyethyleneimine (PEI) is used to form a silica/PEI composite vector. Understanding the interactions at the silica and PEI interface is important for successful DNA delivery and transfection, especially for silica with different surface functionality. Herein, we report that a higher content of hydrogen boning formed between PEI molecules and phosphonate modified silica nanoparticles could slow down the PEI dissolution from the freeze-dried solid composites into aqueous solution than the bare silica counterpart. The pronounced PEI retention ability through phosphonation of silica nanoparticles effectively improves the transfection efficiency due to the high DNA binding affinity extracellularly, effective lysosome escape and high nuclear entry of both PEI and DNA intracellularly. Our study provides a fundamental understanding on designing effective silica-PEI-based nano-vectors for DNA delivery applications.
