2. Nanoparticle-lipid interactions 2.1 当实验温度低于liposome的熔化温度时 使用zwitterionic lipids制备尺寸约为100nm的liposome不稳定。同时这些liposome存在些许的正电。此时引入silica nanoparticles, 硅粒子会对liposome产生稳定的作用。 由于实验温度T=25℃<Tm Tm = 41℃,所以nanoparticle进不去liposome,因为liposome...
脂质体形成过程始于中性脂质溶解于氯仿等有机溶剂中，加热蒸发溶剂后，通过加入缓冲液促使脂质膨胀，形成囊泡。囊泡类型包括多层囊泡（MLV）、大单层囊泡（LUV）和小单层囊泡（SUV），通过施加不同量的机械能可以控制形成的囊泡类型。稳定性和保护方面，通过附着嵌段共聚物，脂质体可以被稳定化，并受到人...
Inkjet printing has the potential to enable novel personalized and tailored drug therapies based on liposome and lipid nanoparticles. However, due to the significant shear force exerted on the jetted fluids, its suitability for shear-sensitive materials such as liposomes, has not been verified. We ...
Fujifilm has been in the healthcare business since the early days of its 90-year history. Today, we provide CDMO services to help our partners develop innovative medicines in the field of biopharmaceuticals. In the field of lipid-nanoparticles (LNPs), Fu
Lipid BilayersLiposomesSpectrometry, FluorescenceDrug Delivery SystemsThe loading and containment of cargo within nanoparticles and their efficient delivery to cells represent a primary challenge in nanomedicine. We report lipid exchange between free and mesoporous silica nanoparticle-supported lipid bilayers as...
Drug delivery is arguably one of the most important and promising areas in nanomedicine. Among the many recently developed drug carriers, inorganic nanomaterials, in particular amorphous mesoporous silica nanoparticles, are very attractive because of their biocompatibility combined with high surface area ...
For this reason, the choice of a (phospho)lipid component is crucial in the liposome preparation. Liposomes can be composed by natural (e.g., phosphatidylcholine) or synthetic phospholipids, but may include other lipid materials, such as cholesterol, and hydrophilic polymers that can affect the ...

The few-nanometer-thin lipid bilayer that defines the liposome nanocontainer is assembled predominantly from zwitterionic POPC. Consequently, it has a low effective surface charge under slightly basic pH (ξ=−1.11±0.82 mV at pH=8.0) and shows much weaker nonspecific interactions with the NPs...
To address the critical need for a transportable, and temperature-stable blood substitute, a bio-synthetic, nano-artificial erythrocyte called Erythromer (EM) [107] has been developed. EM encapsulates human Hb within deformable, hybrid peptidic-lipid nanoparticles. This design, allows for a true ph...
