Protein corona formation in biological fluids can alter nanoparticle cellular uptake, transfection, and gene silencing, but the relationship between LNP surface chemistry and corona-mediated delivery is incompletely understood. This study examined how PEG lipid chain length and PEG molar ratio affect protein corona…

Liposome clinical translation is limited by opsonisation and rapid clearance by immune cells. Although the protein corona is recognised as the liposome’s “biological identity,” it was unclear whether pre-adsorbed corona proteins could help liposomes avoid capture by circulating leukocytes in whole blood and thereby…

Endosomal escape is a key but poorly quantified step for intracellular nucleic acid delivery. Existing methods are low-throughput, indirect, or fail to distinguish endosomal disruption from actual cytosolic cargo delivery. A reliable, sensitive method is needed to rationally optimise polymeric mRNA delivery vehicles…

Nonviral gene delivery remains limited by low transfection efficacy, especially under physiological serum conditions and at low nanoparticle doses. Although linear poly(β-amino ester)s (PBAEs) are effective, branching structure had not been systematically evaluated in well-defined PBAE-like poly(ester amine) systems…

Triple-negative breast cancer (TNBC) lacks effective targeted therapy. Nonviral co-delivery of an anticancer drug and a therapeutic gene may improve treatment, but efficient tumour-targeted co-delivery remains challenging. TRAIL has shown limited clinical benefit alone, and embelin (EMB) can inhibit XIAP to promote…

Ideal cancer nanomedicines need a stealth surface for prolonged circulation and tumour accumulation, but stealth surfaces often hinder cellular uptake. Conversely, cationic or targeting-ligand surfaces enhance uptake but cause rapid clearance and off-target interactions. This review addresses the central conflict…

Despite decades of nanomedicine development for tumour therapy, less than 1% of systemically administered nanocarriers (NCs) accumulate in solid tumours. This is largely due to protein corona formation during blood circulation, which accelerates clearance and masks targeting ligands. Stealthy (neutral/negatively…

miRNAs can regulate about 60% of protein-coding genes and enable targeting of previously “undruggable” proteins and diseases, but their clinical use is limited by nuclease degradation, poor tissue targeting, inefficient cellular uptake, and inadequate cytosolic release. Lipid nanocarriers are a versatile…

Many polymer-based nanoparticle formulations fail before or during clinical trials. This review identifies the key checkpoints a nanocarrier must satisfy after intravenous injection — biocompatibility, drug loading/release, storage stability, biodistribution, target selectivity, cellular internalisation, and…

PLGA is a biocompatible, biodegradable copolymer widely used in drug delivery systems (DDS), but conventional bulk synthesis methods suffer from poor control over particle size, broad size distribution, low drug loading/encapsulation efficiency, and burst release. Microfluidic systems offer a tightly controlled…

Conventional micro/nanoparticle synthesis techniques (e.g., emulsion, sol–gel) can produce only a limited number of shapes—mainly spherical or rod-like—and provide poor control over size, cargo loading, and surface properties. These features critically affect particle–cell interactions and in vivo biodistribution, so…

Lung cancer has the highest mortality among cancers, and single-agent chemotherapy is often unsuccessful due to drug resistance, insufficient intracellular uptake, nonspecific targeting, and severe systemic toxicity. Combination chemotherapy can suppress drug resistance and achieve synergistic anticancer efficacy…

PEGylated pH-sensitive liposomes may improve delivery of anti-cancer peptides, but PEGylation can reduce cellular uptake and endosomal escape (“PEG dilemma”), and it was unknown whether PEGylated liposome components interfere with the intracellular mechanism of action of the delivered drug. Physicochemical…

Tissue engineering needs efficient, biocompatible non-viral gene delivery to mesenchymal stem cells (MSCs), which are inherently refractory to transfection. Existing vectors have limitations: PEI is cytotoxic and linear poly(L-lysine) (L-PLL) has poor transfection efficiency. Transfection efficiency (pGFP, day 7)…

Dendritic cell (DC)-based vaccines require efficient antigen delivery, but free ovalbumin (OVA) is poorly taken up by DCs and is often degraded, sequestered, or exocytosed. Existing OVA delivery systems often suffer from low loading capacity (<10%), lack of imaging ability, or chemical modification that can impair…

Conventional chemotherapy for breast and colon cancers suffers from low specificity, rapid drug clearance, and severe toxic side effects on healthy tissues, while chemoresistance and metastasis remain major causes of cancer-related mortality. There is an unmet need for targeted delivery systems that can co-deliver…

Many anticancer small molecules have poor aqueous solubility, and verteporfin (VP) has mainly been used as a photodynamic therapy agent, which carries photosensitivity and delivery limitations. PBAE-based materials have been developed extensively for nucleic acid delivery but are less explored for non-genetic…

Nanoparticles (NPs) are increasingly used in consumer goods, electronics, and pharmaceuticals, but their beneficial and/or deleterious effects ultimately arise from interactions at the cellular and subcellular level. While many NPs require safe entry into cells for therapeutic efficacy, efficient and controlled…

Surface PEGylation of nanoparticles (NPs) improves circulation time and tumour accumulation but also hinders intracellular delivery, creating the "PEG dilemma" for siRNA therapeutics. While stimuli-responsive de-PEGylation strategies exist, they add complexity to NP design and synthesis. A tunable, serum…

Polyethylenimine (PEI)-based gene delivery is limited by cytotoxicity, rapid degradation, and low cellular uptake. A safer, more stable non-viral system was needed for both gene delivery and gene knockdown. Physicochemical properties: DDC liposomes ~198.7 nm, ζ = −30.9 mV; IPEI polyplexes ~166.2 nm, ζ = +19.1 mV…

Gemcitabine (GEM) monotherapy for pancreatic cancer has poor tumour specificity, short circulation half-life, and drug resistance. Baicalein (BCL) can downregulate Bcl-2/Mcl-1 and sensitise tumour cells, but it has poor solubility, low bioavailability, and rapid metabolism. A targeted co-delivery system was needed to…
