A New Method Without Organic Solvent to Targeted Nanodrug for Enhanced Anticancer Efficacy

Area of Science:

• Nanotechnology
• Materials Science
• Oncology

Background:

• Traditional nanoparticle synthesis often relies on organic solvents, posing potential risks to patients.
• Developing safe and effective drug delivery systems for cancer therapy is crucial.

Purpose of the Study:

• To develop a "green" synthesis method for folate-modified nanoneedles loaded with 10-hydroxycamptothecine (HCPT).
• To evaluate the targeting ability, drug loading, and therapeutic efficacy of these nanoneedles for cancer treatment.

Main Methods:

• Green synthesis of folate-modified nanoneedles (HFNDs) without organic solvents.
• In vitro cell uptake studies using HeLa cells.
• In vitro cytotoxicity and in vivo anticancer experiments.

Main Results:

• HFNDs demonstrated efficient drug loading, targeting properties, and enhanced cellular uptake compared to non-modified nanoneedles.
• Cytotoxicity tests showed superior cancer cell killing ability of HFNDs.
• In vivo studies confirmed pronounced anticancer effects with lower side effects.

Conclusions:

• The developed green synthesis method offers a promising, solvent-free approach for creating targeted nanoneedles for cancer therapy.
• HFNDs represent a viable drug delivery system for improved cancer diagnosis and treatment with enhanced safety profiles.
