Rational Design of Lipids<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A combinatorial chemistry strategy is employed to enable the modular design of ionizable amines, hydrophobic lipid tails, and linker chemistries. By integrating artificial intelligence (AI) with innovative synthetic methodologies, multifunctional lipid libraries are constructed. Lipid nanoparticles (LNPs) with high RNA encapsulation efficiency are subsequently formulated. Through systematic structural optimization, the interactions between LNPs and biological systems are precisely regulated, enabling the efficient development and screening of RNA carrier libraries, including highly safe and effective LNPs as well as low liver-accumulating LNP variants.<\/p>

Inhalable Lung-Targeted RNA Delivery Systems<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

An innovative inhalable RNA delivery platform has been developed to advance therapeutic strategies for respiratory diseases. To address key challenges associated with aerosolized LNPs, including particle size enlargement, reduced encapsulation efficiency, and limited mucus penetration, this approach integrates multidimensional optimization of lipid structures, formulation design, and manufacturing processes. The resulting system exhibits excellent aerosolization stability, favorable aerodynamic properties, and efficient mucus penetrating capability. It has demonstrated robust gene regulation and significant therapeutic efficacy across multiple models of respiratory diseases.<\/span><\/p>

Targeted Lipid Delivery Systems<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A modular lipid co assembly strategy has been developed to enable targeted nucleic acid delivery and drive innovation in therapeutic mechanisms for major diseases. This approach introduces a \u201cmodular molecular assembly\u201d concept, in which functional lipid modules with targeting capabilities are rationally designed and assembled to construct nucleic acid carriers capable of efficient and selective delivery to specific cell types, including hepatic stellate cells, macrophages, and microglia. A \u201cpositive feedback enhanced\u201d targeting mechanism is proposed for the first time, enabling amplified delivery efficiency and therapeutic outcomes. This platform has demonstrated significant efficacy in animal models of cardiovascular, cerebrovascular, and hepatic metabolic diseases, providing new avenues for the treatment of major diseases.<\/p>
