Special Issue Information

Dear Colleagues, 

Rapid and sensitive detection of disease biomarkers and pathogens is the fundamental basics for designing efficient biosensors for healthcare. Electromechanical biosensors are used for the rapid and highly sensitive detection of pathogens and target biomolecules by measuring change in charge and mass on the sensor surface. Cantilever sensors and acoustic wave sensors are two major categories of electromechanical biosensors that have been used successfully for the rapid and sensitive detection of pathogens and important biomarkers. On the other hand, nanoplasmonics-based biosensors combined with microdevices based on microfluidics, lab-on-a-chip, photoacoustic, are showing potential benefits, e.g., sensor miniaturization, multiplex detection, and detection of ultra-low concentration (up to the level of fM) of biomarkers.

Despite all the potentials and applications of the abovementioned biosensing techniques, there is a wide gap between their current applications in biosensing and the ability to make them fit for point-of-care applications. Therefore, in the current Special Issue, we are inviting potential research articles from the field of nanoelectromechanics, nanoplasmonics, and related fields of research that cover the development of cost-effective, portable, and point-of-care biosensors, requiring low-sample consumption and providing high sensitivity and a real-time response.

The photoacoustic (PA) technique is a non-invasive, non-ionizing hybrid technique that exploits laser irradiation for sample excitation and acquires an ultrasound signal generated due to thermoelastic expansion of the sample. Being a hybrid technique, PA possesses the inherent advantages of conventional optical (high resolution) and ultrasonic (high depth of penetration in biological tissue) techniques and eliminates some of the major limitations of these conventional techniques. Hence, PA has been employed for different biomedical applications. In this review, we first discuss the basic physics of PA. Then, we discuss different aspects of PA techniques, which includes PA imaging and also PA frequency spectral analysis. The theory of PA signal generation, detection and analysis is also detailed in this work. Later, we also discuss the major biomedical application area of PA technique. Full article
