Mucoadhesive polymers are critical for anchoring drug delivery devices to specific mucosal sites, enabling localized and sustained drug presence. By prolonging residence time at the site of application, such biomaterials hold the potential to improve drug bioavailability and therapeutic outcomes, particularly in GI delivery platforms. This research explores the mucoadhesive performance of OPM-CRG SPH, which could advance the development of effective GI mucoadhesive drug delivery systems. In vitro mucoadhesion was tested using goat GI mucosa and a texture analyzer, measuring key parameters such as work of adhesion (W<sub>ad</sub>) and maximum detachment force (F<sub>max</sub>) under varying instrumental conditions. In vivo GI-retention studies were conducted on New Zealand rabbits, using X-ray radiography to monitor the formulation’s retention in the GI tract (GIT). Mucoadhesion increased with contact time and force but exhibited minimal change by withdrawal speed. Distinct mucoadhesive behaviors were observed across different GIT segments, with the highest F<sub>max</sub> and W<sub>ad</sub> values recorded in large intestinal tissues. In vivo studies confirmed maximum adherence at higher pH levels, consistent with in vitro findings. X-ray imaging demonstrated successful 8 to 10-h mucoadhesion in rabbits. The hydrogel exhibits promising mucoadhesive properties, making it a viable candidate for GI drug delivery systems. Its ability to adhere effectively across various GI segments and sustain prolonged retention highlights its potential for enhancing drug delivery efficiency.</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":"2025-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145372268","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}

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.
