Abstract
Gold nanoparticles (AuNPs)-based immunochromatographic assay has gained popularity as a rapid detection method for food hazards. Synthesizing highly stable AuNPs in a rapid, simple and environmentally friendly manner is a key focus in this field. Here, we present a green microfluidic strategy for the rapid, automated, and size-controllable synthesis of pepsin-doped AuNPs (AuNPs@Pep) by employing glucose-pepsin as a versatile reducing agent and stabilizer. Through combining the colorimetric and photothermal (PoT) properties of AuNPs@Pep, both "signal-off" and "signal-on" formats of microfluidic paper analytical devices (PADs) were developed for detection of a small molecule antibiotic, florfenicol, and an egg allergen, ovalbumin. Compared to the colorimetric mode, a 4-fold and 3-fold improvement in limit of detection was observed in the "signal-off" detection of florfenicol and the "signal-on" detection of ovalbumin, respectively. The results demonstrated the practicality of AuNPs@Pep as a colorimetric/PoT dual-readout probe for immunochromatographic detection of food hazards at different molecular scales.

SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2023:e2302969. [PMID: 37452511 PMCID: PMC10787806 DOI: 10.1002/smll.202302969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 06/22/2023] [Indexed: 07/18/2023]
Abstract
The first-line treatment for ectopic pregnancy (EP), the chemotherapeutic methotrexate (MTX), has a failure rate of more than 10%, which can lead to severe complications or death. Inadequate accumulation of administered MTX at the ectopic implantation site significantly contributes to therapeutic failure. This study reports the first glutathione-responsive polymersomes for efficient delivery of MTX to the implantation site and its triggered release in placental cells. Fluorescence and photoacoustic imaging have confirmed that the developed polymersomes preferentially accumulate after systemic administration in the implantation site of pregnant mice at early gestational stages. The high concentrations of intracellular glutathione (GSH) reduce an incorporated disulfide bond within polymersomes upon internalization into placental cells, resulting in their disintegration and efficient drug release. Consequently, MTX delivered by polymersomes induces pregnancy demise in mice, as opposed to free MTX at the same dose regimen. To achieve the same therapeutic efficacy with free MTX, a sixfold increase in dosage is required. In addition, mice successfully conceive and birth healthy pups following a prior complete pregnancy demise induced by methotrexate polymersomes. Therefore, the developed MTX nanomedicine can potentially improve EP management and reduce associated mortality rates and related cost.
