Shake flasks are a foundational tool in early process development by allowing high throughput exploration of the design space. However, lack of online data at this scale can hamper rapid decision making. Oxygen transfer rate (OTR) monitoring has been readily applied as an online process characterization tool at the benchtop bioreactor scale.

Here, lipopeptides (LPs) prepared by conjugation of the nuclear-targeting peptide analogue H-YKQSHKKGGKKGSG-NH (NrTP6) and two lauric acid chains are used to encapsulate the chemotherapeutic agent doxorubicin (DX) through a solvent-exchange protocol. LPs spontaneously form nanosized rod-like assemblies in phosphate buffer.

Infants with gastroschisis rely on total parenteral nutrition (TPN) preoperatively, and due to intestinal function and dysmotility issues, continue to face feeding challenges postclosure, including feeding intolerance and increased risk of necrotizing enterocolitis (NEC). Postclosure, human milk-feeding is preferred over infant formula because of its associated reduced risk of feeding intolerance and NEC.

Covalent conjugation of DEX to PAH has been achieved through a straightforward reductive amination approach, allowing for a controlled number of DEX chains per PAH polymer (PAH:DEX, n = 0.1, 0.
