Background:

• Nanogels represent a promising drug delivery platform due to their stability and versatile drug-loading capabilities for various agents.
• Composite nanogels function as multifunctional systems, capable of carrying drugs, genes, and diagnostic agents for theranostic applications.

Purpose of the Study:

• To explore the potential of nanogel-based drug delivery systems for advanced cancer therapy.
• To highlight the role of nanogels in stimuli-responsive drug release and targeted delivery of therapeutic agents.

Main Methods:

• Design and synthesis of nanogel platforms for drug encapsulation.
• Incorporation of targeting ligands for enhanced accumulation at tumor sites.
• Development of stimuli-responsive nanogels for controlled drug release within the tumor microenvironment (TME).

Main Results:

• Nanogels demonstrate effective loading of both hydrophobic and hydrophilic drugs.
• Stimuli-responsive nanogels enable precise release of chemo-/immunotherapy drugs, reprogramming TME cells.
• Ligand-functionalized nanogels improve targeted drug delivery and therapeutic efficacy.

Conclusions:

• Multifunctional nanogels offer a sophisticated platform for targeted drug delivery and combination cancer therapies.
• Nanogel-based systems enhance the precision of cancer treatment by improving drug distribution and therapeutic outcomes.
• Advanced nanogels possess tumor tissue-editing properties, paving the way for novel immunotherapeutic strategies.
