Exogenous genes are inserted into target cells during gene therapy in order to compensate or rectify disorders brought on by faulty or aberrant genes. However, gene therapy is still in its early stages because of its unsatisfactory therapeutic effects which are mainly due to low transfection efficiency of vectors, high toxicity, and poor target specificity. A natural polymer with numerous bioactive sites, good mechanical qualities, biodegradability, biocompatibility, and processability called silk fibroin has gained attention as a possible gene therapy vector.

Bacterial cellulose, with mechanical strength, high water absorption, and crystallinity, is used in eco-friendly packaging, wound dressings, and drug delivery systems. Despite its potential, industrial-scale production is limited by inefficiency and high costs, requiring high-yield strains and optimized growth conditions. This study found that indigenous isolates produce superior bacterial cellulose compared to standard strains.

Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer defined by the lack of three key receptors: estrogen, progesterone, and HER2. This lack of receptors makes TNBC difficult to treat with hormone therapy or drugs, and so it is characterised by a poor prognosis compared to other kinds of breast cancer. This study explores photoactive Poly(lactic-co-glycolic acid) (PLGA) nanoparticles as a potential therapeutic strategy for TNBC.

Targeted drug delivery is a promising strategy for treating inflammatory diseases, with recent research focusing on the combination of neutrophils and nanomaterials. In this study, a targeted nanodrug delivery platform (Ac-PGP-tFNA, APT) was developed using tetrahedral framework nucleic acid (tFNA) along with a neutrophil hitchhiking mechanism to achieve precise delivery and anti-inflammatory effects. The tFNA structure, known for its excellent drug-loading capacity and cellular uptake efficiency, was used to carry a therapeutic agent─baicalin.

In this context, we reported for the first time the design and development of a self-assembled nanoantiviral pesticide based on the star polycation (SPc) and the broad-spectrum fungicide/antiviral agent seboctylamine for field control of (SMV), a highly destructive plant virus in soybean crops. The SPc could self-assemble with seboctylamine through hydrogen bonds and van der Waals forces, and the complexation with SPc reduced the particle size of seboctylamine to form a spherical seboctylamine/SPc complex. In addition, the contact angle of seboctylamine decreased, and its retention increased with the aid of SPc, indicating excellent wetting properties and strong leaf surface adhesion performance.
