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…

Gene therapy requires efficient delivery of genetic material, but viral vectors carry risks of immunogenicity, toxicity, and cancer formation. Cationic polymers such as polyethyleneimine (PEI) can condense DNA and facilitate delivery, but their lack of biodegradation causes significant toxicity due to polymer…

Polymeric nanocarriers such as dendrimers, micelles, nanoparticles, nanogels, nanocapsules, and vesicles are widely investigated for drug delivery, but their morphology, surface chemistry, and functionalisation strongly influence drug loading, controlled release, and targeting. This review addresses the need for a…

Gene therapy requires safe and effective delivery vectors. PBAEs are biodegradable cationic polymers with excellent gene delivery properties, but a comprehensive and critical overview of their use as gene carriers is lacking. This review provides the first comprehensive and critical overview of PBAE-based gene…

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…

Polymer–drug conjugates have achieved clinical success, especially PEG–protein conjugates, but translation of many conjugates—particularly polymer–small-molecule anticancer therapeutics—remains limited. This review addresses the need for rational design, better understanding of in vivo barriers, and identification of…

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…

mRNA-based cancer vaccination is a promising approach for personalised immunotherapy, but safe and effective mRNA delivery remains a major challenge due to mRNA's instability and poor cell membrane permeability. While lipid nanoparticles (LNPs) are the primary delivery strategy, they have limitations with respect to…

Genetic modification of human T lymphocytes is critical for both basic research and emerging therapies (e.g., CAR-T cells), but established non-viral methods are highly inefficient. Linear polyethylenimine (l-PEI), the "gold standard" for non-viral transfection of mammalian cells, achieves only single-digit…

Efficient mRNA delivery to lymphocytes remains a major unmet need for immunotherapy and vaccinology. Current methods rely largely on physical transfection such as electroporation, which is ex vivo, costly, and inefficient; chemical vectors generally achieve low lymphocyte mRNA transfection, especially in vivo. Lead…

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)…

CAR T cell immunotherapy requires efficient ex vivo gene delivery to primary human T cells, but viral vectors have limitations including cost, cargo size, insertional mutagenesis risk, and manufacturing complexity. Non-viral cationic polymers are attractive alternatives but historically show low gene transfer…

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…

Artificial antigen-presenting cells (aAPCs) are promising for immune modulation, and anisotropic (ellipsoidal) particles have shown improved T-cell stimulation over spherical particles. However, widely used methods for generating anisotropic particles, such as thin-film stretching, can be difficult to implement…
