This study investigated a bubble trapping mechanism integrated into microfluidic chip to address this issue. Microfluidic chip design includes a high shear stress section of fluid flow that can generate up to 2.7 Pa and two strategically placed bubble traps. Commercially available magnets are used for fabrication, effectively reducing production costs. The trapping efficiency is assessed through video recordings with a phone camera and analysis of captured air volumes by injecting dye at flow rates of 50, 100, and 150 µL/min. This assessment uses L*A*B* color space with analysis of the perceptual color difference ∆E and computational fluid dynamics (CFD) simulations. The results demonstrate successful application of the bubble trap mechanism for lab-on-chip bubble detection, effectively preventing bubbles from entering microchannels and mitigating potential damage. Furthermore, the correlation between the L*A*B* color space and volume fraction from CFD simulations allows accurate assessment of trap performance. Therefore, this observation leads to the hypothesis that ∆E could be used to estimate the air volume inside the bubble trap. Future research will validate the bubble trap performance in cell cultures and develop efficient methods for long-term air bubble removal.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":490,"journal":{"name":"Biomedical Microdevices","volume":"27 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10544-024-00727-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142963043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, wireless sensors eliminate the need for a battery or energy harvester, reducing the size of the sensor.

To prevent complications, here we proposed a non-contact sensor module to rapidly detect such events. The system does not interfere with the human skin, nor contaminating the flowing medication since only biocompatible materials are exposed to the liquid. The proposed sensor module was assembled as a flow channel with flow rate and pressure sensing functions. The flow rate sensing was realized using a micromachined thermal flow sensor fabricated on a thin polyimide film, while the pressure sensing was realized using a diaphragm structure and a MEMS pressure sensor.

Here, a platform that consists of three main components is introduced: a portable housing, a centrifugal microfluidic disc, and a mobile phone. The mobile phone supplies the electrical power and serves as an analysing system. The low-cost housing made from cardboard serves as a platform to conduct tests. The electrical energy stored in mobile phones was demonstrated to be adequate for spinning a centrifugal disc up to 3000 revolutions per minute (RPM), a rotation speed suitable for majority of centrifugal microfluidics-based assays. For controlling the rotational speed, a combination of magnetic and acoustic tachometry using embedded sensors of the mobile phone was used. Experimentally, the smartphone-based tachometry was proven to be comparable with a standard laser-based tachometer. As a proof of concept, two applications were demonstrated using the portable platform: a colorimetric sandwich immunoassay to detect interleukin-2 (IL-2) having a limit of detection (LOD) of 65.17 ng/mL and a fully automated measurement of hematocrit level integrating blood-plasma separation, imaging, and image analysis that takes less than 5 mins to complete.

In this paper, we describe a simple protocol for rapid functionalization of microbubbles and show how to use them inside a microfluidic chip to develop a novel type of biosensor.

The microbubbles are then organized inside a chamber before injecting the fluid with the bioanalyte of interest through the static bubbles network. In this proof-of-concept demonstration, we use streptavidin as the bioanalyte of interest. Both functionalization and capture are assessed using fluorescent microscopy thanks to fluorescent labeled chemicals.
