Background:

Developing advanced nanocarriers for targeted drug delivery is crucial.
Stimuli-responsive materials offer precise control over drug release.
Hollow nanostructures provide encapsulation benefits.

Purpose of the Study:

To synthesize and characterize novel hollow shell-shell nanogels.
To investigate their potential for controlled drug delivery applications.
To understand the role of dual polymer shells in responsive behavior.

Main Methods:

Small-angle neutron scattering (SANS) with contrast variation.
Molecular dynamics (MD) simulations.
Synthesis of hollow nanogels with distinct volume phase transition temperatures.

Main Results:

Demonstrated temperature-dependent swelling of inner and outer shells.
Identified a critical temperature range (32°C–42°C) for optimal void size and stability.
Confirmed temperature-controlled molecular encapsulation and release via simulations.
Achieved void sizes larger than the initial template core.

Conclusions:

Hollow shell-shell nanogels are promising for controlled drug delivery.
Dual-shell responsiveness allows fine-tuning of drug uptake, release, and carrier stability.
The system offers tunable colloidal stability through outer shell swelling.
