Nucleic acid biosensors
… aptamers) and fluorescence microscopy to create biosensors for the detection of DNA and proteins. As a step towards fulfilling the goal of developing a second generation of sophisticated sensors, signaling aptamers were engineered. Signaling aptamers are nucleic acid ligands (aptamers) that are …

Aptamers as biosensors
Aptamers are short, single strands of artificial nucleic acids which bind to specific targets. This binding is similar to the binding exhibited by antibodies but aptamers offer improved properties and consequently are replacing antibodies in some applications. This first part of this project …

Atomically thin microwave biosensors
This thesis described the development of a new type of biosensor based on the integration of atomically thin graphene in a broadband radio-frequency (RF) coplanar waveguide (CPW). To combine both electrochemical and dielectric sensing concepts, a graphene channel is inserted into the CPW, which can …

Heterogeneously Integrated Impedance Based Biosensors
The salient issues of integrated biosensors on a complementary metal-oxide semiconductor (CMOS) platform are the limited transducer design and the need for post-processing. To overcome these issues, a heterogeneously integrated system, which employs both CMOS and large-area processing, was proposed …

Autonomous cricket biosensors for acoustic localization
… was to design networked arrays of cricket biosensors capable of localizing sources such as footsteps within dangerous environments, with a possible application to earthquake detection. We utilize the cricket's natural ability to localize low frequency (5 Hz - 600 Hz) acoustic sources using …

Evolution-Inspired Design of Bacterial Biosensors
Bacterial signal transduction systems are critical tools for synthetic biology. However, while hundreds of thousands of systems have been identified in bacterial genomes, only a small subset have been characterized. In this work, we develop tools for scalable interrogation of bacterial signal …
