Article Abstract

All pharmaceutical manufacturers are required to verify that their production equipment is free from contaminants. Here, we report the capability of a fully automated portable capillary electrophoresis instrument with an integrated sample swab extraction - the Grey Scan ETD-100 - for the detection of pharmaceutical residues on surfaces of manufacturing equipment. Lidocaine was used as a model compound and could be recovered from a surface by swabbing, extracted from the swab, and analysed within 1 min. The recovery of lidocaine from a stainless-steel coupon was 81.3 %, with a LOD of 0.13 µg/swab. This fast, sensitive, and simple method implemented on a user-friendly portable CE instrument without the need for manual sample pre-treatment provides the possibility for on-site rapid determination of equipment cleanliness in the pharmaceutical industry.

The rapid adoption of mRNA-based vaccines highlights the critical need for on-site quality control (QC) methods, particularly in low-income countries with decentralized manufacturing. Existing techniques, such as liquid chromatography-mass spectrometry (LC-MS) and capillary electrophoresis (CE), are resource-intensive, requiring specialized equipment and expertise. To address this, a comprehensive lateral flow strip assay (LFSA) has been developed to evaluate key mRNA quality attributes-5' capping efficiency, integrity, and lipid nanoparticles (LNPs) encapsulation efficiency.

Astringency, a complex oral sensation resulting from interactions between mucin and polyphenols, remains difficult to quantify in portable field settings. Therefore, quantifying the aggregation through interactions can enable the classification of the astringency intensity, and assessing the capillary action driven by the surface tension offers an effective approach for this purpose. This study successfully replicates tannic acid (TA)-mucin aggregation on a paper-based microfluidic chip and utilizes machine learning (ML) to analyze the resulting capillary flow dynamics.

Miniature mass spectrometer-based point-of-care assay for measuring three psychiatric drugs in human plasma and whole blood.

Developing a rapid, simple method to detect psychiatric drug concentrations is essential, as it facilitates long-term monitoring of treatment efficacy and is critical for managing drug poisoning in clinical settings due to abuse or accidental overdose. Conventional laboratory-based assays used for monitoring psychiatric medications often demonstrate prolonged processing times, leading to considerable delays in adjusting treatment regimens. To address this, this study introduced a point-of-care testing (POCT) approach using a miniature mass spectrometer, which allows for rapid and precise measurement of three psychiatric drugs including carbamazepine (CBZ), quetiapine (QTP), and olanzapine (OLZ) in human plasma and whole blood.

Moisture-enabled electricity generator (MEG) technology converts energy from the environment into green electricity by exploiting the interaction between atmospheric moisture and hydrophilic materials and has the advantages of a simple device structure, small geographical and temporal constraints, and environmental friendliness; therefore, it has great application value in serving as a power source for portable electronic devices. However, the high output performance of most MEG devices is dependent on high ambient relative humidity (RH), and current MEG technologies tend to be poorly flexible and lack wearability, which severely pose a barrier to their practical utilization. Here, we have developed a high-performance bilayer MEG with exceptional environmental adaptability and stretchability.

This study presents the development of a novel highly efficient light-trapping 3D Au plasmonic cone-arrays-in-bowl (CAIB) surface-enhanced Raman scattering (SERS) platform. The innovative platform integrates a pump-free microfluidic device with a highly sensitive SERS detection system. The CAIB structures are fabricated using a combination of techniques, including polystyrene sphere self-assembly, inductively coupled plasma etching, and electron beam deposition.
