Sample pretreatment for mass spectrometry (MS)-based metabolomics and lipidomics is normally conducted independently with two sample aliquots and separate matrix cleanup procedures, making the two-step process sample-intensive and time-consuming. Herein, we introduce a high-throughput pretreatment workflow for integrated nontargeted metabolomics and lipidomics leveraging the enhanced matrix removal (EMR)-lipid microelution 96-well plates. The EMR-lipid technique was innovatively employed to effectively separate and isolate non-lipid small metabolites and lipids in sequence using significantly reduced sample amounts and organic solvents.

Background And Purpose: Liquid self-nanoemulsifying drug delivery systems (SNEDDS) face challenges related to stability, handling, and storage. In particular, lipophilic and unstable drugs, such as ramipril (RMP) and thymoquinone (THQ), face challenges in oral administration due to poor aqueous solubility and chemical instability. This study aimed to develop and optimize multi-layer self-nanoemulsifying pellets (ML-SNEP) to enhance the stability and dissolution of ramipril (RMP) and thymoquinone (THQ).

The current study aimed to synthesize a ZIF-8 metal-organic framework loaded with the Rose Bengal (ZIF-8@RB) as the photodynamic sterilization ingredient to address the uncontrolled release of active ingredients in packaging films. The photodynamic controlled release packaging film was then prepared using a PVDF polymer matrix via uniaxial electrospinning. The microstructure, particle size, excitation wavelength, and singlet oxygen yield of ZIF-8@RB were examined.

The FeO@RF-ISB nanomaterial was prepared through the chemical immobilization of (3-aminopropyl)trimethoxysilane over the FeO@RF composite, followed by treatment with isatin. The FeO@RF-ISB was then reacted with FeCl·6HO to afford the FeO@RF-ISB/Fe nanocatalyst.
