Advances in Multiple Stimuli-Responsive Drug-Delivery Systems for Cancer Therapy

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Conventional nanomedicines face challenges in complex physiological fluids and tumor microenvironments.
• Stimuli-responsive drug-delivery systems represent a promising advancement for cancer therapy.
• Existing nanomedicines often fail to achieve desired therapeutic effects due to biological barriers.

Purpose of the Study:

• To provide a comprehensive overview of multiple stimuli-responsive drug-delivery systems (MSR-DDSs) for cancer treatment.
• To highlight recent design strategies for MSR-DDSs.
• To discuss the advantages and clinical translation obstacles of MSR-DDSs in oncotherapy.

Main Methods:

• Review of current literature on stimuli-responsive nanomedicines.
• Analysis of design principles for multi-stimuli triggered nano-carriers.
• Evaluation of therapeutic potential and clinical challenges.

Main Results:

• MSR-DDSs, triggered by multiple stimuli across different biological levels, can overcome sequential barriers.
• These systems facilitate targeted delivery of therapeutic payloads.
• MSR-DDSs provide a platform for co-delivery of agents and overcoming multidrug resistance.

Conclusions:

• MSR-DDSs demonstrate significant potential for enhancing cancer therapy.
• Strategic design of MSR-DDSs is crucial for overcoming physiological and pathological barriers.
• Further research is needed to address obstacles hindering the clinical translation of MSR-DDSs.
