Silica-based Nanoparticles for Enzyme Immobilization and Delivery.

Area of Science:

• Biotechnology
• Nanomedicine
• Enzyme Engineering

Background:

• Enzymes are crucial biocatalysts but suffer from instability and poor delivery.
• Natural enzymes face limitations like vulnerability, low reusability, and biological barriers.
• Silica-based nanoparticles (SNPs) offer tunable properties to overcome these enzyme limitations.

Purpose of the Study:

• To summarize recent advancements in using SNPs for enzyme immobilization and delivery.
• To highlight therapeutic applications of enzyme-loaded SNPs, particularly in cancer therapy and bacterial inhibition.
• To provide perspectives on current challenges and future research directions in this field.

Main Methods:

• Enzyme immobilization onto silica-based nanoparticles.
• Characterization of enzyme-loaded SNPs for stability and activity.
• In vitro and in vivo evaluation of therapeutic efficacy.

Main Results:

• SNPs significantly improve enzyme activity, durability, and reusability.
• SNPs enable precise spatiotemporal control over enzyme biodistribution.
• Enzyme-loaded SNPs demonstrate promising therapeutic outcomes in cancer and bacterial infections.

Conclusions:

• SNPs are effective carriers for enhancing enzyme performance and overcoming biological barriers.
• Enzyme-based nanotherapeutics hold great potential for treating diseases like cancer and bacterial infections.
• Further research is needed to address challenges and fully realize the potential of enzyme-SNP systems.
