Hybrid nanocrystals embed imaging agents for drug delivery, enabling simultaneous therapy and bioimaging. This technique allows detailed study of drug pharmacokinetics and dissolution within the body.
Area of Science:
- Pharmaceutical Sciences
- Biomedical Engineering
- Materials Science
Background:
- Nanocrystals are promising for delivering poorly water-soluble drugs, but their in vivo behavior is not fully understood.
- Traditional nanocrystallization focuses on drug dissolution enhancement.
- The dying crystal phenomenon led to hybrid nanocrystals for improved drug delivery and imaging.
Purpose of the Study:
- To introduce the hybrid nanocrystal technique for drug delivery and bioimaging.
- To discuss the preparation, theoretical concepts, and applications of hybrid nanocrystals.
- To highlight advancements in self-discriminative hybrid nanocrystals using environment-responsive probes.
Main Methods:
- Embedding fluorophores into the crystal lattice of drug nanocrystals.
- Utilizing the dying crystal phenomenon to create hybrid structures.
- Developing environment-responsive probes for self-discriminative nanocrystals.
Main Results:
- Hybrid nanocrystals enable concurrent therapy and in vivo bioimaging.
- This approach facilitates the study of pharmacokinetics and nanocrystal dissolution.
- Nanocrystals demonstrate long-term durability for biological interactions.
Conclusions:
- Hybrid nanocrystal technology offers a powerful tool for theranostic drug delivery.
- Further development is expected to advance nanocrystal-based theranostic strategies.
- This technique enhances understanding and application of nanocrystal drug delivery systems.
