Development of Functionalized Liposomes Liposomes prepared via traditional methods often exhibit poor batch-to-batch reproducibility and considerable variation in particle size and properties, limiting many research projects to the lab stage. Microfluidic technology enables liposomes withconsistent batch-to-batch quality, controllable particle size and properties, and the ability to carry multiple drugs, particularly advantageous for targeted tumor drug delivery. The core of microfluidic technology isconverging two-phase fluids to form nanoscale particles. By incorporating different drugs into the two phases, dual-drug loading is achievable; adding functionalized phospholipids or ligands attached to phospholipids in the organic phase may allow for the one-step production of multifunctional liposomes.
3) Hydrogel Microspheres Delivery vectors for small-molecule drugs or growth factors Hydrogel microspheres can protect, deliver, and locally release drugs (such as small molecule drugs or growth factors). The early use of hydrogel microspheres for drug delivery was in plastic surgery to enablesustained release of growth factors, aiding bone and cartilage repair. Hydrogel microspheres are also frequently used inpulmonary drug deliveryand as carriers forgrowth factor delivery within microtissues研究によると、インターロイキン-10を含んだハイドロゲルマイクロスフィアは心臓修復を促進することが示されており、また、ハイドロゲルマイクロスフィアは胃でのインスリンの分解を保護し、患者が注射からより便利な経口投与に切り替えることを可能にします。 ハイドロゲルマイクロスフィアの製造方法 ハイドロゲルマイクロスフィアを製造するための一般的な方法には、バルク乳化、マイクロ流体乳化、リソグラフィ、静電スプレー、および機械的破砕が含まれています。マイクロ流体乳化法は効果的にハイドロゲルマイクロスフィアの形成プロセスを制御し、指定された形状のマイクロスフィアを生成します。
