The traditional treatment modalities, such as chemotherapy, surgery, and radiotherapy, are often associated with significant toxicity to healthy tissues and systemic side effects, highlighting the pressing need for safer and more targeted therapeutic strategies. Recently, microneedle innovation has become an evident alternative for delivering anti-neoplastic agents, offering minimally invasive, transdermal administration that can bypass hepatic metabolism and reduce systemic toxicity. Microneedle (MNs) arrays hold potential not only for drug delivery but also for vaccination, diagnostic sampling, and targeted therapy in BC management. However, despite these promising attributes, there exists a notable gap in the scientific literature specifically addressing the application of microneedles in breast cancer therapy, with relatively few comprehensive studies in this domain. This review aims to bridge that gap by summarizing recent advancements in MN-based strategies for breast cancer treatment. It highlights the ability of MNs to enable simultaneous drug loading, controlled release, and improved patient compliance through non-invasive administration. Furthermore, the review discusses MN properties, mechanisms of action, therapeutic benefits, relevant clinical trials, patents, and future challenges, thereby providing a valuable resource for researchers and promoting the translation of MN technology into clinical practice for breast cancer management.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":490,"journal":{"name":"Biomedical Microdevices","volume":"27 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents the design, fabrication, and characterization of a SAW sensor employing a Polydimethylsiloxane (PDMS) microfluidic channel as a dual-function waveguide to effectively localize Love Wave (LW) confinement and convert Rayleigh waves to LW. Utilizing a comprehensive approach integrating multi-parametric Finite Element Analysis (FEA), analytical modeling, and experimental validation, two SAW devices with distinct interdigitated transducer (IDT) electrode configurations (12 μm and 38 μm width and spacing) have been developed. FEA and experimental results consistently confirm the superior performance of the 12 μm electrode configuration. This device achieved significant BAW suppression, evidenced by a low insertion loss (S21) of -57 dB (FEA) and a narrow admittance peak (Δf = 0.6 MHz at FWHM), yielding a high Q-factor at its center frequency (fc = 82.5 MHz). Performance metrics for the 12 μm electrode configuration include a reflection coefficient (S11) of -85 × 10⁻⁷ dB (vs. -40 × 10⁻⁸ dB for 38 μm), experimental insertion losses of -64.86 dB, -67.05 dB, and − 69.27 dB for 50, 40, and 30 finger pairs respectively, and low limit of detection (LoD) with higher number of finger pairs. The PDMS waveguide maximized acoustic energy confinement at the surface, enabling efficient Love wave propagation, which minimizes dissipative losses in Liquids. Moreover, the dominant y-direction surface displacement of 0.026 μm, and a higher admittance peak (80 × 10⁻⁷), indicating high sensitivity in liquid medium and high quality (Q) factor, respectively. The sensor’s micro-particle detection capability, based on monitoring IL changes – established as an effective metric for quantifying particle-induced perturbations in flow-through configurations – across varying particle concentrations, has been experimentally validated using 10 μm diameter Polystyrene (PS) particles as Lactobacillus analogs. The strong agreement between analytical, FEA, and experimental results validates this high-fidelity SAW device with integrated microfluidics as a promising, cost-effective, and highly sensitive platform for micro-particle detection in liquid media, with potential extension to gas sensing applications, if used without any waveguide.</p></div>","PeriodicalId":490,"journal":{"name":"Biomedical Microdevices","volume":"27 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our system, called CLogging Elimination ActuatoR Silicone (CLEARS), integrates a soft, expandable silicone tube within the catheter lumen. This soft robotic insert, capable of 900% strain, can inflate to dislodge blockages and then deflate to restore flow. To test CLEARS, we developed an ex vivo model simulating CSF flow and obstruction using a rapidly acting clogging agent. ICP upstream of the catheter was monitored to evaluate performance. When obstructed with 3 g of the clogging agent, ICP rose to 30 cmH<span>(_2)</span>O. Upon CLEARS activation, the silicone insert expanded through catheter ports and successfully removed the clog, restoring baseline ICP (<span>(sim)</span>0 cmH<span>(_2)</span>O) within approximately 40 s. Without the system, obstruction persisted and pressure remained elevated. Visual documentation confirmed the mechanism of action. The CLEARS system offers a promising solution to VP shunt occlusion by enabling non-invasive mechanical declogging. Our model replicates shunt obstruction and CSF dynamics, providing a testbed for device evaluation. The expandable insert maintained catheter flow and reduced ICP to normal levels after obstruction, representing a potential shift in how hydrocephalus is treated.</p></div>","PeriodicalId":490,"journal":{"name":"Biomedical Microdevices","volume":"27 3","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10544-025-00769-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032630","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}

We prepared a nanocomplex by combining graphene with bovine serum albumin (BSA) in PBS and subjecting it to ultrasonication.

The successful modification of the EIS biosensor surface with Graphene/BSA/GA and aptamer immobilization was confirmed using atomic force microscopy (AFM), which indicated successful molecule attachment through surface roughness. Electrochemical characterization revealed that the biosensor is sensitive to ATP concentrations ranging from 0.1 nM to 100 nM, with a detection limit as low as 0.32 nM. Statistical analysis demonstrated the biosensor’s high sensitivity and specificity for ATP. Furthermore, the biosensor maintained stable performance for ATP detection over a period of 5 days.
