What is Nanoparticle Drug Delivery Systems?

Nanoparticle Drug Delivery Systems are engineered nanoscale carriers designed to encapsulate therapeutic agents, enhance targeted delivery, and control release kinetics for improved pharmacokinetics and bioavailability.

These systems utilize metallic nanoparticles like silver and gold, often biosynthesized from plant extracts, to deliver drugs with antibacterial, anticancer, and antifungal properties. Key methods include green synthesis using plant materials such as Dypsis lutescens and Salvia officinalis for chitosan-capped nanoparticles. Over 200 papers exist on biosynthesis and applications, with foundational work on metal ions dating to 2018 (Mittapally et al., 89 citations).

Key Challenges

Why It Matters

Nanoparticle systems improve therapeutic indices by reducing side effects in cancer treatments, as herbal nanocarriers target cervical and breast cancers (Damani et al., 2020; Moremane et al., 2023). Silver nanoparticles synthesized from plant extracts show strong in-vitro antibacterial activity against gram-negative bacteria, addressing antimicrobial resistance (Akshaya et al., 2022). Sustained release polymers maintain constant drug levels, enhancing oral bioavailability (Subramani et al., 2021). These applications lower toxicity in inflammatory and infectious disease models.

Key Research Challenges

Scalable Green Synthesis

Biosynthesis of stable nanoparticles from plant extracts faces reproducibility issues across batches due to variable phytochemical content (Arya et al., 2019). Scaling from lab to industrial levels reduces encapsulation efficiency. Chemical methods remain dominant despite green synthesis advantages (Al‐Sarraj et al., 2023).

Targeted Release Control

Achieving precise pharmacokinetics in vivo remains difficult, with premature release limiting bioavailability (Subramani et al., 2021). Disease model testing shows variable uptake in cancer cells. Polymer degradation rates need optimization for sustained delivery.

Toxicity and Biocompatibility

Metallic nanoparticles like silver risk cytotoxicity despite antimicrobial benefits (Mittapally et al., 2018). Long-term safety in human trials lacks data, especially for herbal nanocarriers (Damani et al., 2020). Balancing efficacy with reduced side effects challenges clinical translation.
