Special Issue Information

Dear Colleagues,

In a world of ever-increasing early-stage detection and treatment demand of devastating diseases (e.g., Alzheimer’s disease), recent advances in the use of plasmonic biosensors have proven that they are promising tools for better public health. Unlike other possible treatment modalities, such as chemotherapy, radiation therapy, and surgery, well-designed biosensing platforms based on optical signal transduction mechanisms, particularly the plasmonic biosensors as a counterpart of photonic biosensors, have the role of possessing innovative solutions as a bridge between biological/medical needs and sensing technologies. Within this framework, the transformative rise of plasmonic tools provides a potentially safer toolbox both at the cellular and molecular level by enabling high-throughput, label-free, quick, real-time, low-cost, high-specificity, and ultrasensitive detection.

Harnessing enhanced light-matter interactions through specialized building blocks, plasmonics technology has been getting involved in a new phase of biomedical and biochemical point-of-care analyses. From a more applied perspective, researchers are now able to tailor and produce next-generation plasmonic instruments for on-site theranostics and modern clinical applications, by improving their reliability, responsivity, and sensitivity one step further.

In this Special Issue of Biosensors, we seek state-of-the-art research and development efforts in the field of plasmonic biosensors. Both original article and review submissions are welcome.

The accumulation of metal ions in the body is caused by human activities and industrial uses. Among these metal ions, copper is the third most abundant ion found in the human body and is indispensable for health because it works as a catalyst in the iron absorption processes. However, high doses of copper ions have been reported to generate various diseases. Different types of sensors are used to detect metal ions for several applications. To design selective and specific recognition sites on the sensor surfaces, molecular imprinting is one of the most used alteration methods to detect targets by mimicking natural recognition molecules. In this study, an ion-imprinted polymer-integrated plasmonic sensor was prepared to selectively detect copper (Cu(II)) ions in real-time. Following different characterization experiments, the Cu(II)-imprinted plasmonic sensor was employed for kinetic, selectivity, and reusability studies. According to the results, it was observed that this sensor can measure with 96% accuracy in the Cu(II) concentration range of 0.04–5 μM in buffer solution. The limit of detection and limit of quantification values were computed as 0.027 µM and 0.089 µM. The results also showed that this plasmonic sensor works successfully not only in a buffer solution but also in complex media such as plasma and urine. Full article
