Stoppin (L1) is a newly identified anticancer peptide, which is a potent p53‑MDM2/MDMX inhibitor. Due to its limitation in cell delivery efficiency, a new peptide delivery system was developed based on a nucleic acid‑polypeptide‑liposome complex and its stability and effectiveness in vitro was investigated. The nucleic acid‑stoppin‑liposome complex was prepared and characterization of the compl...

Incorporation of membrane proteins into reconstituted lipid membranes is a common approach for studying their structure and function relationship in native-like environment. In this work, we investigated fluorescence properties liposome-reconstituted major light-harvesting complexes plants (LHCII). By utilizing liposome labelling with the fluorescent dye molecules single-molecule microscopy tec...

Hybrid liposome/metal nanoparticles are promising candidate materials for biomedical applications. However, the poor selectivity and low yield of the desired hybrid during synthesis pose a challenge. We designed a programmable liposome by selective encoding of a reducing agent, which allows self-crystallization of metal nanoparticles within the liposome to produce stable liposome/metal nanopart...

Liposomes are spherically shaped phospholipid bilayers that used to encapsulate hydrophilic or lipophilic drugs. To have efficient drug delivery by a liposome, it should be able deliver the specific binding site, where can affect target. However, sometimes, due untimely release, this goal cannot achieved. Therefore, permeation rate of through liposomal membrane is important, as affects drug’s r...

The dynamics of liposome solubilization was monitored by dynamic light scattering and optical microscopy. A newly designed Y-shape microchannel connected to a room was incorporated into a microchip and the reaction processes of the liposome suspension and surfactant solution were observed in the room after mixing the two fluids and stopping the flow. By using this microchip, we succeeded in r...

We developed selective transfection of single particle sensor into a specific cell by optically controlled cell immobilization and membrane fusion of liposome for intracellular measurement. The particle was encapsulated in the liposome using packaging based on multi-layering method. The liposomes contain 1,3,3-Trimethylindolino-6'nitrobenzopyrylospiran (SP) that controls the surface potential o...

Nanoliposome can be designed as a drug delivery carrier to improve the pharmacological and therapeutic properties of drug administration. (188)Re-labeled nanoliposomes are useful for diagnostic imaging as well as for targeted radionuclide therapy. In this study, the in vivo nuclear imaging, pharmacokinetics and biodistribution of administered nanoliposomes were investigated as drug and radionuc...
