Abstract
BACKGROUND Genetic drugs have aroused much attention in the past twenty years. RNA interference (RNAi) offers novel insights into discovering potential gene functions and therapies targeting genetic diseases. Small interference RNA (siRNA), typically 21-23 nucleotides in length, can specifically degrade complementary mRNA. However, targeted delivery and controlled release of siRNA remain a great challenge. METHODS Different types of lipid-based delivery vehicles have been synthesized, such as liposomes, lipidoids, micelles, lipoplexes and lipid nanoparticles. These carriers commonly have a core-shell structure. For active targeting, ligands may be conjugated to the surface of lipid particles. RESULTS Lipid-based drug delivery vehicles can be utilized in anti-viral or anti-tumor therapies. They can also be used to tackle genetic diseases or discover novel druggable genes. CONCLUSION In this review, the structures of lipid-based vehicles and possible surface modifications are described, and applications of delivery vehicles in biomedical field are discussed.

Abstract
Cationic conjugated polyelectrolytes can absorb negatively charged small interfering RNA (siRNA) and also visualize the cellular internalization of siRNA, which thus have been extensively explored as siRNA carriers. However, their low charge density cannot afford a high carrying capability, severely impeding gene transfection efficiency. Moreover, the intracellular controlled release of siRNA is another factor that limits the widespread use of siRNA therapeutics. Herein, we present a novel two-photon-induced charge-variable conjugated polyelectrolyte brush as an efficient siRNA carrier. This cationic conjugated polyelectrolyte brush (PPENBr-ONB) with densely cationic charges produces remarkable carrying capability with siRNA. In addition, PPENBr-ONB with large two-photon absorption (TPA) cross-section represents effective fluorescence resonance energy transfer (FRET) to photoresponsive side chain with 720 nm illumination for two-photon-induced photolysis. Hence, the charge transformation of the photoresponsive side chain from cations to zwitterions would remarkably elevate siRNA release. The obtained PPENBr-ONB shows considerable fluorescence quantum yields (0.16) in aqueous solution, sufficient to serve as a reporter for cellular imaging. Agarose gel electrophoresis experiments indicate that PPENBr-ONB exhibit excellent siRNA-loading capacity (1 mol PPENBr-ONB to more than 20 mol siRNA). Furthermore, PPENBr-ONB with large TPA cross-section (1.47 × 105 GM) exhibits promoted siRNA release (78%) under 720 nm illumination. In vitro experiment shows that PPENBr-ONB/siRNA complex could efficaciously knock out of targeted Plk1 mRNA to 24.7% under 720 nm illumination for 1 h. This two-photon excitation siRNA carrier offers an efficacious strategy for the exploitation of photo controlled gene delivery system.

Abstract
DNAzymes are catalytically active DNA molecules that are normally isolated through in vitro selection methods, among which RNA-cleaving DNAzymes that catalyze the cleavage of a single RNA linkage embedded within a DNA strand are the most studied group of this DNA enzyme family. Recent advances in DNA nanotechnology and engineering have generated many RNA-cleaving DNAzymes with unique recognition and catalytic properties. Over the past decade, numerous RNA-cleaving, DNAzymes-based functional probes have been introduced into many research areas, such as in vitro diagnostics, intracellular imaging, and in vivo therapeutics. This review focus on the fundamental insight into RNA-Cleaving DNAzymes and technical tricks for their intracellular and in vivo applications, highlighting the recent progress in the clinical trial of RNA-Cleaving DNAzymes with selected examples. The challenges and opportunities for the future translation of RNA-cleaving DNAzymes for biomedicine are also discussed.

Abstract
Owing to its hydrophilicity, negative charge, small size, and labile degradation by endogenous nucleases, small interfering RNA (siRNA) delivery must be achieved by a carrier system. In this study, cationic copolymers composed of low-molecular-weight polyethylenimine and polythiophenes were synthesized and evaluated as novel self-tracking siRNA delivery vectors. The concept underlying the design of these copolymers is that hydrophobicity and rigidity of polythiophenes should enhance the transport of siRNA across the cell membrane and endosomal membrane. A gel retardation assay showed that the nanosized complexes formed between the copolymers and siRNA were stable even at a molar ratio of 1 : 2. The high cellular uptake (>80%) and localization of the copolymer vectors inside the cells were easily analyzed by tracking the fluorescence of polythiophene using fluorescent microscopy and cytometry. An in vitro luciferase knockdown (KD) assay in A549-luc cells demonstrated that the siRNA complexes with more hydrophobic copolymers achieved a higher KD efficiency of 52.8% without notable cytotoxicity, indicating protein-specific KD activity rather than solely the cytotoxicity of the materials. Our polythiophene copolymers should serve as novel, efficient, low cell toxicity, and label-free siRNA delivery systems.

Abstract
We report here an effective Pb2+-dependent DNAzyme (8-17 DNAzyme) delivery system based on the water-soluble dendritic polyethylene-cationic poly(p-phenylene ethynylene) for successfully imaging Pb2+ in living cells. For utilizing the 8-17 DNAzyme and its unique ability to catalyze a phosphodiester bond cleavage reaction in the presence of Pb2+, the distinctive conjugated polymer-based polyvalent nanocarrier design manages to load and transport 8-17 DNAzyme across cell membranes, and to realize the fluorescence imaging of Pb2+ in living cells. As shown by the confocal microscopy and flow cytometry observations, the fluorescence of Cy5.5 is obviously activated under the conditions of incubation with Pb2+, compared with the absence of Pb2+. Taken together, the study demonstrates the combination of the molecular-wire effect with "dendrimer effects" on their effective DNAzyme delivery and their cellular imaging Pb2+.
