With the advancements in nanotechnology and biomaterials science, the development of nanodrug delivery systems (Nano-DDSs) has provided opportunities for the realization of precise targeted treatment of malignant tumors. Liposomes have become a type of DDS with early clinical application and mature development due to their excellent tissue-targeting capacity and outstanding biocompatibility. However, several obstacles remain, such as recognition and clearance by the immune system, a short half-life, and poor tumor targeting. To address these problems, we propose a new method to transform liposomes, using fusion to reassemble the extracted natural cell membranes and artificial phospholipids to form a composite nanolipid carrier (recombined lipid nanocarriers (RLNs)). We evaluated the different types of cell membrane composite lipid nanocarriers based on parameters such as particle size, stability, drug loading and release capabilities, in vitro and in vivo tumor-targeting efficacy, and safety. The results indicated that these novel tumor cell-derived membrane fusion lipid nanocarriers exhibited promising antitumor effects and safety profiles, offering insights for precision cancer treatment.

Erastin, as an effective ferroptosis inducer, has received extensive attention in anti-tumor research. To develop an oral nanocarrier for high efficient loading hydrophobic erastin, here we prepared a fluoro-liposome (FA-3 F-LS) by the self-assembly of the folic acid modified fluorinated amphiphiles-FA-3 F conjugates. The hydrophobic component of three perfluorooctyl chains endows the FA-3 F-LSs with high stability to resist the harsh gastrointestinal tract condition.

Glioblastoma multiforme (GBM) is considered to be one of the most devastating brain tumors with a shorter life expectancy. Several factors contribute to the dismal prognosis of GBM patients including the complicated nature of GBM, the ability of tumor cells to resist treatment, and the difficulty of delivering drugs to the brain because of barriers like the blood-brain barrier (BBB) and blood-tumor barrier (BTB). The unique challenges posed by the BBB in delivering therapeutic agents to the brain have led to the development of innovative nanotechnology-based approaches.

Lipid-based nanocarriers provide versatile platforms for the encapsulation and delivery of many different bioactive compounds to improve the solubility, stability and therapeutic efficacy of bioactive phyto-compounds. In this study, liposomes were used to load leaf extract of Coffea Arabica, which is known to be rich beneficial substances such as alkaloids, flavonoids, etc. The aim of this work is to optimize the valorization of agricultural wastes containing natural antioxidants.
