Saliva is an underused fluid with considerable promise for biomedical testing. Its potential is particularly great for monitoring small-molecule analytes since these are often present in saliva at concentrations that correlate well with their free levels in blood. We describe the development of a prototype diagnostic device for the rapid detection of the antiepileptic drug (AED) phenytoin in saliva. The multicomponent system includes a hand-portable surface plasmon resonance (SPR) imaging instrument and a disposable microfluidic assay card.

Conductive nanofibers can exhibit excellent mechanical properties such as flexibility, elasticity, porosity, large surface area-to-volume ratio, etc making them suitable for a wide range of applications including biosensor development. Their large surface area provides more active sites for immobilization of large amount of bioreceptors enabling more interaction sites with the target analytes, enhancing sensitivity and detection capabilities. However, engineering conductive nanofibers with such excellent properties is challenging limiting their effective deployment for intended applications.

Nickel-based metal-organic frameworks, denoted as three-dimensional nickel trimesic acid frameworks (3D Ni-TMAF), are gaining significant attention for their application in nonenzymatic glucose sensing due to their unique properties. Ni-MOFs possess a high surface area, tunable pore structures, and excellent electrochemical activity, which makes them ideal for facilitating electron transfer and enhancing the catalytic oxidation of glucose. This research describes a new electrochemical enzyme-mimic glucose biosensor in biological solutions that utilizes 3D nanospheres Ni-TMAF created layer-by-layer on a highly porous nickel substrate.

Prenatal sonographic diagnosis of congenital heart disease (CHD) can lead to improved morbidity and mortality. However, the diagnostic accuracy of ultrasound, the sole prenatal screening tool, remains limited. Failed prenatal or early newborn detection of cyanotic CHD (CCHD) can have disastrous consequences.

While few methodological studies have been published on the salivary measurement of malondialdehyde (MDA), none have precisely detailed the analytical method. This work presents the development of an analytical method for MDA measurement in microvolumes of saliva samples from healthy individuals, using thiobarbituric acid derivatization and fluorescence reading of the formed compound. This method was progressively designed to meet specific constraints such as the limited sample volume available, cost-effectiveness of each assay, time required for analysis and costs.

Photonic crystal-based aptasensors for viral proteins detection offer the advantage of producing visible readouts. However, they usually suffer from limited sensitivity and high non-specific background noise. A significant contributing factor to these issues is the use of fixed-conformation aptamers in these sensors.
