Special Issue Information

Dear Colleagues,

You are kindly invited to submit original research and review articles to this new Special Issue dedicated to the most recent developments in the emerging field of biosensing-drug delivery systems. Despite the progress made in chemical sensor development, titratable drug delivery systems, and closed-loop therapies, there are still many challenges that need to be addressed in order for these systems to realize their full potential and have a significant impact on medical practice and patient outcome. This Special Issue aims, therefore, to showcase the latest trends in biosensing-drug delivery systems, such as in smart and stimuli-responsive materials (hydrogels, electrospun fibers) and in fabrication designs for wearable and impantable bioMEMS and microfabricated devices; novel concepts such as the integration of delivery devices with mobiles for continuous monitoring of drug dose and physiological response in disease conditions (diabetes, epilepsy and pain to name but a few) will also be presented. It is my hope that this Special Issue will gather the latest advances in the field, so that it can serve the entire scientific community in helping to improve the strategies for the design of such systems and boost their translation from benchtop to healthcare and in vivo applications.

Firefly luciferases catalyze the efficient production of yellow-green light under normal physiological conditions, having been extensively used for bioanalytical purposes for over 5 decades. Under acidic conditions, high temperatures and the presence of heavy metals, they produce red light, a property that is called pH-sensitivity or pH-dependency. Despite the demand for physiological intracellular biosensors for pH and heavy metals, firefly luciferase pH and metal sensitivities were considered drawbacks in analytical assays. We first demonstrated that firefly luciferases and their pH and metal sensitivities can be harnessed to estimate intracellular pH variations and toxic metal concentrations through ratiometric analysis. Using Macrolampis sp2 firefly luciferase, the intracellular pH could be ratiometrically estimated in bacteria and then in mammalian cells. The luciferases of Macrolampis sp2 and Cratomorphus distinctus fireflies were also harnessed to ratiometrically estimate zinc, mercury and other toxic metal concentrations in the micromolar range. The temperature was also ratiometrically estimated using firefly luciferases. The identification and engineering of metal-binding sites have allowed the development of novel luciferases that are more specific to certain metals. The luciferase of the Amydetes viviani firefly was selected for its special sensitivity to cadmium and mercury, and for its stability at higher temperatures. These color-tuning luciferases can potentially be used with smartphones for hands-on field analysis of water contamination and biochemistry teaching assays. Thus, firefly luciferases are novel color-tuning sensors for intracellular pH and toxic metals. Furthermore, a single luciferase gene is potentially useful as a dual bioluminescent reporter to simultaneously report intracellular ATP and/or luciferase concentrations luminometrically, and pH or metal concentrations ratiometrically, providing a useful tool for real-time imaging of intracellular dynamics and stress.
