Micro/Nanoparticle Encapsulation via EHD
Research Guide
What is Micro/Nanoparticle Encapsulation via EHD?
Micro/Nanoparticle encapsulation via electrohydrodynamics (EHD) uses electrostatic forces in coaxial electrospray and electrospinning to coat drugs, proteins, and cells with polymeric shells for controlled release.
EHD techniques produce core-shell particles from nano to micron sizes through charged fluid jets (Ramakrishna et al., 2013, 585 citations). Coaxial setups enable precise payload protection and tunable release kinetics. Over 1,100 citations across key reviews highlight biomedical applications.
Why It Matters
EHD encapsulation protects sensitive payloads like antibiotics from degradation, enabling local transdermal delivery as shown in BC/PCL patches with amoxicillin, ampicillin, and kanamycin (Altun et al., 2021, 65 citations). Janus particles with degradable compartments achieve differential release for targeted therapies (Hwang and Lahann, 2012, 73 citations). Ramakrishna et al. (2013, 585 citations) demonstrate enhanced solubility and biocompatibility for nanomedicine, impacting drug delivery systems with over 585 citations.
Key Research Challenges
Jet Instability Control
Unstable EHD jets cause irregular particle sizes and morphologies during encapsulation (Robinson et al., 2019, 258 citations). Taming melt electrospinning jets requires precise voltage and flow balancing. This limits scalability for uniform micro/nanoparticles.
Payload Encapsulation Efficiency
Coaxial electrospray often results in incomplete core-shell formation for biologics (Yurteri et al., 2010, 111 citations). Low water solubility of herbal extracts reduces loading in nanofibers (Liu et al., 2023, 75 citations). Biocompatibility testing remains inconsistent across scales.
Release Kinetics Prediction
Modeling differential degradation in Janus particles is complex due to interpenetrating networks (Hwang and Lahann, 2012, 73 citations). Environmental triggers alter shape and release unpredictably (Lee et al., 2012, 94 citations). Validation requires extensive in vitro studies.
