Currently, there is no effective method to assess oxygen levels in extravascular retinal tissue. Traditional hypoxia detection methods, such as oxygen-sensitive microelectrodes, magnetic resonance imaging, and retinal oximetry, have limitations including invasiveness, low spatial resolution, and lack of real-time monitoring. Herein, a noninvasive hypoxia detection method is proposed by utilizing lipid-polymer nanoparticles (NPs) with purely organic room-temperature phosphorescence materials for real-time detection with high spatial and temporal resolution. To enhance biocompatibility and efficacy, NPs were fabricated using biodegradable poly(lactic-co-glycolic acid) (PLGA) and SeCO as a phosphor. PLGA degrades into nontoxic by-products, while the excitation wavelength of SeCO at 393 nm minimizes damage from short wavelengths and enhances tissue penetration. Furthermore, the NPs’ size is optimized to improve cellular uptake and reduce bodily accumulation, as smaller NPs are preferred for biocompatibility. Herein, synthesis, characterization, and evaluation of these PLGA-based phosphorescent NPs in rabbit models of retinal vein occlusion and choroidal vascular occlusion are involved. This approach represents a significant advancement in noninvasive biomedical imaging, improving the diagnosis and management of ischemic retinal diseases.","PeriodicalId":29975,"journal":{"name":"Advanced Nanobiomed Research","volume":"5 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/anbr.202400153","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, maintaining signal quality over time is complicated by inflammatory tissue responses and degradation of electrode materials. Organic electrode coatings offer a solution by enhancing recording and stimulation capabilities, including reduced impedance, increased charge injection capacity, and the ability to incorporate and release anti-inflammatory drugs. Herein, acid-functionalized multiwalled carbon nanotubes (CNTs) loaded with dexamethasone (Dex) are incorporated into poly(3,4-ethylendioxythiophene) (PEDOT) as electrode coatings. The electrochemical stability and recording performance of the PEDOT/CNT/Dex coating over an extended period of ≈18 months are investigated. Cyclic voltammetry (CV) stimulation is used to release Dex in half of the recording sites during the first 11 days of implantation to reduce the acute inflammation. The PEDOT/CNT/Dex-coated floating microelectrode arrays demonstrate stable in vivo electrode impedance and successful detection of visually evoked neural activity from the rat visual cortex even at chronic time points. Additionally, the CV-stimulated sites exhibit higher single-unit (SU) recording yield, amplitudes, and signal-to-noise ratio compared to unstimulated sites. These results highlight the potential of anti-inflammatory treatments to improve the quality and longevity of chronic neural recordings.","PeriodicalId":29975,"journal":{"name":"Advanced Nanobiomed Research","volume":"5 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/anbr.202400114","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the scientific community continues to pursue improvements in diagnostic methods and subsequent treatments. To enhance treatment efficacy and reduce the probability of adverse outcomes, reliable and sensitive diagnostic methods are essential. A potential solution may lie in the synergy between nanotechnology and optical biosensors, as they can provide exceptional sensitivity in the detection of disease biomarkers. This review focuses on fluorescent DNA probes assembled onto metal nanoparticles for cancer-related applications. These hybrid biosensors exhibit remarkable and versatile optical properties enabling to enhance signal emission by orders of magnitude. In these configurations, metallic particles function as optical antennas for fluorescent dyes, significantly increasing their photon emission rates. This review presents a novel perspective on recent advancements in cancer diagnostics and treatment utilizing hybrid biosensors. Current methodologies for cancer diagnostics are examined, toward elucidating their advantages and limitations. The subject matter is critically evaluated, and fundamental concepts are explored to assess the most promising avenues for clinical applications.

Despite these advances, further progress in material performance and device designs is required to ensure seamless, reliable, biocompatible, and high-fidelity cardiac interfacing. Herein, the development of a soft multichannel cardiac patch based on a bifacial architecture of adhesive/low-impedance hydrogel nanocomposites and highly conductive elastomer nanocomposites is reported. The bifacial design facilitates the integration of the cardiac patch between the heart and other tissues/organs can be achieved. The hydrogel nanocomposite layer, positioned on the epicardial side, provides stable adhesion to the target cardiac tissue and enables low-impedance biocompatible interfacing with the heart, while the elastomer nanocomposite layer, positioned on the opposite side, offers high electrical conductivity for facile electrophysiological signal transfer and a low-friction surface minimizing unwanted interactions with surrounding tissues.

Estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) are the primary biomarkers which inform breast cancer treatment. Although endocrine therapy for ER+ patients is widely available, there is a need for increased access to low-cost, rapid, and accurate ER testing methods. In this work, we designed a near-infrared optical nanosensor using single-walled carbon nanotubes (SWCNT) as the transducer and an anti-ERα antibody as the recognition element. We evaluated the nanosensor in vitro prior to testing with 26 breast cancer samples which were collected by scraping the cut surface of fresh, surgically resected tumors. Twenty samples were ER+, and six ER−, representing 13 unique patients. We found that the nanosensor can differentiate ER− from ER+ patient biopsies through a shift in its center wavelength upon sample addition. Receiver operating characteristic area under the curve analyses determined that the strongest classifier with an AUC of 0.94 was the (7,5) SWCNT after direct incubation and measurement, and without further processing. We anticipate that further testing and development of this nanosensor may push its utility toward field-deployable, rapid ER subtyping with the potential for additional molecular marker profiling.","PeriodicalId":29975,"journal":{"name":"Advanced Nanobiomed Research","volume":"5 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/anbr.202400099","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143114665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
