Mrinal K. Hota, et al., "Integration of Electrochemical Microsupercapacitors with Thin Film Electronics for On‐Chip Energy Storage". Advanced Materials 31(25), 2019, 1807450. The development of self‐powered electronic systems requires integration of on‐chip energy‐storage units to interface with various types of energy harvesters, which are intermittent by nature. Most studies have involved on‐chip electrochemical microsupercapacitors that have been interfaced with energy harvesters through bulky Si‐based rectifiers that are difficult to integrate. This study demonstrates transistor‐level

Sandeep G. Surya, et al., "A Chitosan Gold Nanoparticles Molecularly Imprinted Polymer Based Ciprofloxacin Sensor." RSC Advances 10 (22), 2020, 12823. In this work, we present a novel study on the development of an electrochemical biomimetic sensor to detect the ciprofloxacin (CIP) antibiotic. A chitosan gold nanoparticles decorated molecularly imprinted polymer (Ch-AuMIP) was used to modify the glassy carbon electrode (GCE) for preparation of the sensor. The Ch-AuMIP was characterized to understand various properties like chemical composition, morphology, roughness, and conduction using

Tutku Beduk, et al., "A Paper-based Inkjet-printed PEDOT: PSS/ZnO Sol-gel Hydrazine Sensor." Sensors and Actuators B: Chemical 306, 2020, 127539. Hydrazine is widely used in industries as a precursor for blowing agents, pharmaceuticals, and pesticides. It is a highly toxic compound; therefore, it is of paramount interest to develop new analytical methods for the detection and control of hydrazine exposure. In this work, we describe the fabrication of an all inkjet-printed paper sensor composed of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) electrode functionalized with

Tutku Beduk, et al., "One-step Electrosynthesized Molecularly Imprinted Polymer on Laser Scribed Graphene Bisphenol A Sensor." Sensors and Actuators B: Chemical 314, 2020, 128026. Bisphenol A (BPA) is a toxic chemical used by industries for production of containers for storage of food and beverages leading to possible health risks. In this work, we present a simple, mask-free, low-cost imprinted sensor based on laser scribed graphene (LSG) technology combined to molecularly imprinted polymers (MIPs) for BPA determination. CO2 laser was used in production of LSG electrodes with high
