Thermosensitive Liposomal Drug Delivery Systems
Summary
Thermosensitive liposomal drug delivery systems comprise lipid-based vesicles engineered to release encapsulated therapeutics when exposed to mild hyperthermia, typically in the range of 39–43 °C. By incorporating lipids or polymers that undergo a gel-to-liquid crystalline phase transition at a defined temperature, these formulations remain stable in circulation yet release their payload rapidly upon local heating. Triggering mechanisms include external modalities such as focused ultrasound, radiofrequency ablation or magnetic resonance-guided high-intensity focused ultrasound. The combination of spatially precise heating and rapid drug liberation enhances intratumoural accumulation, maximises therapeutic index and reduces systemic exposure. Key design parameters encompass lipid composition, inclusion of lysolipids to accelerate release, PEGylation for prolonged circulation and optimisation of phase transition temperature. Preclinical and early clinical studies have demonstrated improved efficacy of anthracyclines and small-molecule inhibitors in solid tumours when delivered via thermosensitive liposomes, highlighting their potential to overcome limitations of conventional chemotherapy and passive nanoparticle accumulation.

Thermosensitive Liposomal Drug Delivery Systems publication trend
The graph below shows the total number of articles in thermosensitive liposomal drug delivery systems across all publications each year (not limited to Nature Index journals).
Technical terms
Thermosensitive liposome: A lipid vesicle engineered to undergo a controlled phase transition at elevated temperature, triggering rapid drug release.
Phase transition temperature (Tm): The characteristic temperature at which lipid bilayers shift from an ordered gel state to a fluid crystalline state, enabling payload liberation.
Hyperthermia: The therapeutic elevation of tissue temperature, typically to 39–43 °C, used to activate thermosensitive carriers and enhance tumour perfusion.
PEGylation: The attachment of polyethylene glycol chains to nanoparticle surfaces to increase circulation time and reduce immunogenicity.
Enhanced permeability and retention (EPR) effect: Passive accumulation of nanoscale carriers within tumours due to leaky vasculature and impaired lymphatic drainage.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
