Particle Trajectory Simulation Facilitates the Development of an Efficient Sample Introduction System for Single-Particle ICP-MS Analysis.

Inductively coupled plasma mass spectrometry (ICP-MS) has demonstrated significant capabilities in the analysis of single events, such as single cells and particles. Researchers have been actively pursuing innovations in ICP-MS sample introduction systems to enhance their transport efficiency, as this is critical for ensuring the accuracy of single-event analysis. However, the majority of prior studies have relied heavily on empirical approaches, with limited attention given to the individual characteristics of particles from a theoretical perspective and a lack of efficient manufacturing tools for optimizing related components.

Improving fat globule structure to narrow metabolite gap between human milk and infant formulae.

We hypothesized that improving the fat globule structure of infant formulae based on the milk fat globule membrane (MFGM) would regulate metabolites and metabolic pathways, making it more similar to the metabolic properties of human milk. Therefore, we prepared infant formulae with different fat globule structures, including two model infant formulae (F1: fat globules surrounded by MFGM; F2: fat globules surrounded by protein) and one commercial infant formulae containing MFGM, and compared their metabolic differences with those of human milk. The number of differential metabolites between each sample and human milk reached 60 (F1), 132 (F2) and 126 (IF1).
