Volumetric Imaging Efficiency (VIE) compares the compactness and capacity of an imager against the limit imposed by diffraction. This metric is used to compare optical technologies for low-volume imaging and show that a combination of metasurface lenses can surpass the VIE limits of conventional imagers.

Unlike conventional detectors that rely on photocurrent, the open circuit voltage photodetector architecture relies on a detector operating in zero bias. The output from the detector is coupled to the gate of a FET in sub-threshold region. Radiometric characterization of this detector will be discussed.

Optoelectronic technologies based on organic semiconductors (OSCs) have witnessed a dramatic increase in recent decades, with impressive demonstrations of new functionality, devices, and commercial applications, largely based on donor-acceptor conjugated polymers (DA CPs). Open-shell and high-spin configurations bring new notions of spin manipulation, magnetism, quantum properties and interrelated optoelectronic functionalities at the forefront of research efforts in diverse fields. Although extensively studied, the intrinsic instability of these electronic configurations complicates synthesis and precludes an understanding of how fundamental properties manifest in practical applications. To this end, we have implemented new macromolecular design paradigms and strategies to control orbital topology such that very low bandgap DA CPs were synthesized in order to yield open-shell species in singlet (S = 0) and triplet (S = 1) spin states. Electron spin resonance (ESR) and superconducting quantum interference device magnetometry (SQUID) studies are critical to provide insight into ground state of these system and in the exploration of new phenomena derived from electron correlation in related materials.

Redox reactions are widely utilized as a transduction modality for biological to electrical communication. Biomaterial-based redox capacitors are emerging as a promising bio-device interface, since the redox-cycling current from interaction of a pair of mediators with the redox capacitor film can be amplified when the redox potentials of the mediators bracket that of the capacitor. We present a method to further amplify the signal responses of a standard catechol-chitosan redox capacitor (Fig. 1(i)) by carrying out the electrofabrication and electrochemical signal measurements on nanoporous gold (NPG) (Fig. 1(ii)) patterned in a microfluidic channel (Fig. 2a). Specifically, a pH-responsive chitosan film is electrodeposited on an NPG covered gold electrode, which is electrochemically grafted with catecholic species and modified by a self-assembled monolayer of mercapto-hexanol to enable electrochemical measurements under ambient conditions. The resulting nanoporous architecture of the "NPG/redox-capacitor" enhances the spatial extent across the film depth that is available to the redox mediator for electron transfer interactions with the electrode before escape into the bulk film (Fig. 1 (ii)), thereby enabling significantly higher capacity versus that obtained on a conventional redox capacitor (Fig. 2b). The sensitivity and biocompatibility of this NPG/redox-capacitor are validated on a micro-device platform by demonstrating its ability to quantitatively detect the redox active bacterial metabolite: pyocyanin, directly from growth cultures of the opportunistic pathogen: Pseudomonas aeruginosa. Due to the capability for microfluidic integration, we envision that this NPG/redox-capacitor electrofabrication strategy can widely impact studies on biological to electrical communication, including for measurement of human performance biomarkers.
