Optical biosensors are frontrunners for the rapid and real-time detection of analytes, particularly for low concentrations. Among them, whispering gallery mode (WGM) resonators have recently attracted a growing focus due to their robust optomechanical features and high sensitivity, measuring down to single binding events in small volumes. In this review, we provide a broad overview of WGM sensors along with critical advice and additional “tips and tricks” to make them more accessible to both biochemical and optical communities. Their structures, fabrication methods, materials, and surface functionalization chemistries are discussed. We propose this reflection under a pedagogical approach to describe and explain these biochemical sensors with a particular focus on the most recent achievements in the field. In addition to highlighting the advantages of WGM sensors, we also discuss and suggest strategies to overcome their current limitations, leaving room for further development as practical tools in various applications. We aim to provide new insights and combine different knowledge and perspectives to advance the development of the next generation of WGM biosensors. With their unique advantages and compatibility with different sensing modalities, these biosensors have the potential to become major game changers for biomedical and environmental monitoring, among many other relevant target applications.

Gelatin based hydrogels are often incorporated with supporting materials such as chitosan, poly(vinyl alcohol), alginate, carbon nanotubes, and hyaluronic acid. These hybrid materials are specifically of interest in diversified nanomedicine fields as they exhibit unique physicochemical properties, antimicrobial activity, biodegradability, and biocompatibility. The applications include drug delivery, wound healing, cell culture, and tissue engineering. This paper reviews the various up-to-date methods to fabricate gelatin-based hydrogels, including UV photo-cross-linking, electrospinning, and 3D bioprinting. This paper also includes physical, chemical, mechanical, and biocompatibility characterization studies of several hybrid gelatin hydrogels and discusses their relevance in nanomedicine based applications. Challenges associated with the fabrication of hybrid materials for nanotechnology implementation, specifically in nanomedicine development, are critically discussed, and some future recommendations are provided.

“…Plazma bir gaza elektrik akımı verilerek oluşturulur ve elektronlar, iyonlar, atomlar ve reaktif türler içerir [1-2]. Soğuk plazma olarak da adlandırılan termal olmayan plazmalar, düşük gaz sıcaklıklarında üretilir, plazma içerisindeki iyon sıcaklığı oda sıcaklığında iken, elektron sıcaklığı (>10.000 K) çok yüksektir [1,3,4,5]. Bu sayede, malzeme yüzeyleri zarar görmeden, etkili bir şekilde değiştirilebilmektedir.…”

ABSP (Atmosferik Basınçlı Soğuk Plazma) işlemi, polimer ve metal malzemelerin yapıştırma uygulaması öncesinde yüzey özelliklerini geliştirerek istenilen düzeye getirebilmek için yaygın olarak kullanılmaktadır. ABSP, ekonomik ve çevre dostu bir yöntem olup malzeme yüzeyleri etkili bir şekilde değiştirilir. Bu çalışmada, polipropilen (PP) ve galvaniz kaplı çelik (H300LAD) malzeme yüzeylerinin modifikasyonu için soğuk plazma yöntemi kullanılmıştır. Uygulama mesafesi ve işlem (paso) sayısı parametrelerinin belirtilen malzemelerin yapışma bağı dayanımları üzerindeki etkisi araştırılmıştır. ABSP uygulama sonrası, malzemelerin yapışma davranışını değerlendirebilmek amacıyla çekme testi kullanılmıştır. ABSP’nin yapışma dayanımı üzerindeki etkisi, temas açısı ölçümleriyle de ilişkilendirilmiştir. ABSP uygulaması sonrası, malzemelerin yapışma mukavemetinde belirgin oranda artış gözlenmiş, malzemeye daha yakın uygulama yapıldığında daha yüksek yapışma mukavemeti değerlerine ulaşılacağı sonucuna ulaşılmıştır.
