NSP’s functional lipid-PEG were contributed to gold nanorods for photothermal-based antibacterial activity

Skin is considered as the ideal site for non-invasive skin therapeutic platforms. In a recent study published in Scientific Reports,  a library of gold nanorods (GNR) decorated with polyethylene glycol-thiol (PEG-SH) containing different functionalities were synthesized and characterized. The results demonstrated that cholesterol-PEG coated GNR were preferentially loaded up in the upper layers of skin (stratum corneum), while phospholipid-PEG coated counterparts were drastically deposited in skin dermis. Neutral methoxy-PEG-coated GNR were distributed in both SC and dermis skin layers, while charged GNR (anionic-carboxylic acid-PEG-GNR and cationic-amine-PEG-GNR) revealed a minimal accumulation into skin. DSPE-PEG-GNR and Chol-PEG-GNR demonstrated antibacterial activities against Staphylococcus aureus (S aureus) at MIC values of 0.011 nM and 0.75 nM, respectively. Photothermal treatment for S. aureus at sub-MIC concentrations resulted in a significant bactericidal effect when using Chol-PEG-GNR but not DSPE-PEG-GNR. Gold-based nanoscale systems have great value as a promising platform for skin diseases therapy. Scientific Reportsvolume 9, Article number: 5796 (2019). 

NSP’s functional PLA-PEG-NH2 was used in Nanoengineering of Mesenchymal Stem Cells via Surface Modification for Efficient Cancer Therapy

Mesenchymal stem cells (MSCs) can be used for tumor‐specific delivery of small molecular weight anticancer drugs by using nanoparticle‐encapsulated forms of the drugs. In a recent study, an advanced nanoengineering strategy is reported here that involves generation of MSCs expressing azide functional groups on their surface and conjugation of dibenzyl cyclooctyne‐functionalized nanoparticles by PLA-PEG-NH2 (Nanosoft Polymers) to the azide groups using copper‐free click chemistry. This novel strategy significantly improves the payload capacity of MSCs (≈48 pg of paclitaxel (PTX) per cell) relative to that reported previously (<1–20 pg per cell), without affecting their native phenotype. In vivo, the nanoengineered MSCs significantly inhibit tumor growth (p < 0.05) and improve survival (p < 0.0001) compared to free or nanoparticle encapsulated PTX and Abraxane in an orthotopic ovarian tumor model. In summary, the nanoengineering strategy reported here allows for improved delivery and anticancer efficacy of conventional chemotherapeutic agents using MSCs as drug carriers.  Adv.
