In this study, we report the develop and optimization of a simple highly sensitive electrochemical platform for HER2. Gold electrode surface was modified with a self-assembled monolayer composed by DNA aptamer, 6-(ferrocenyl) hexanethiol and 6-mercapto-1-hexanethiol. Electrochemical impedance spectroscopy was used to quantify the changes in capacitance on the interface due to the presence ferrocene, whether acting as a redox charge or its behavior under different HER2 concentration in PBS and undiluted human serum. As a result, the approach allows detection of HER2 with a limit of detection of 3.61 pg/mL, 12.28 nF sensitivity per decade and a linear range from 1 pM to 1 <span>(:mu:)</span>M in serum.

PDT comprises two general steps: the introduction of PS into the body or a specific spot to be treated, and the irradiation process using a light source with a specific wavelength to excite the PS. Although PDT is gaining great attention owing to its potential as a targeted approach in the treatment of skin cancers, several limitations still exist for practical use. One of the biggest challenges is the limited penetration of light owing to scattering, reflection, and absorption of light inside the skin layers. In addition, accidental light exposure of the target area causes additional cellular damage, which causes unexpected complications. To solve these issues, we introduced an optical microneedle–lens array (OMLA) to improve the efficiency and safety of PDT treatment. We designed and fabricated a novel optical microneedle–lens array with controlled dimensions to optimize light transmission. In addition, PS was coated uniformly over the tips of the OMLA using the dip coating method. Finally, we confirmed that the PS coated on the OMLA was released into the target area and subsequently generated radical oxygen by light irradiation. We expect that our proposed OMLA for PDT treatment can realize a new light-transmission platform optimized for PDT with targeting various types of skin cancers.</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":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11775042/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143051241","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}

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.
