2020.8 Md Ashiqur Rahman Laskar joined our lab as a Ph.D. Student. Welcome, Ashiqur!

2020.8 Dr. Wang is supported by NSF for DNA based storage and readout technologies (
This SemiSynBio II award supports our collaboration with Prof. Hao Yan and Prof. Rizal Hariadi to explore the programmability of DNA nanostructures for the encryption keys, making it practically impossible to intercept and break the encryption. The research team will embed encrypted information in three-dimensional DNA origami nanostructures in the form of nanoscopic patterns. The high spatial resolution of DNA-PAINT (DNA-based point accumulation for imaging in nanoscopic topography) (<20 nm) and sapphire-supported nanopore sensors (<10 nm) will support high-density information decryption of intricate single-molecule patterns on the DNA origami, while enabling a fast readout speed of up to 1 MHz. The fast readout methods will employ deep-learning classification techniques for automated decryption and improved accuracy.

2020.4 Dr. Wang is supported by NSF to develop an new sapphire based nanopore device for low-noise DNA sensing.(
This NSF-BSF award supports our collaboration with Prof. Amit Meller at Technion to carry out fundamental research to create a significantly improved nanopore sensor platform that integrates low-optical background titanium oxide membranes on low-capacitance and hence low-electrical-noise sapphire. The research team will fabricate small and thin TiO2 membranes on sapphire, establish high-throughput manufacturing methods for both membrane formation and nanopore drilling, perform single-molecule DNA translocation, study the DNA-nanopore interaction, and analyze the data for methylation detection.

2020.4 Our paper (Printing continuous metal structures via polymer-assisted photochemical deposition ) in collaboration with Dr. Yu Yao has been published on Materials Today (Impact factor 24)
This work is also reported here on ASU Now.

2019.12 Dr. Wang and collaborator Dr. Yu Yao are supported by NSF to develop an additive manufacturing method to print silver structures with micrometer resolution and at ambient conditions for functional electronic and photonic applications.(
This award supports fundamental research to help develop a room-temperature AM process that enables high-resolution printing without thermal damage. The new process will utilize solution-based layer-by-layer deposition to produce highly reflective and highly conductive metal microstructures directly from soluble metal salts. The metallic microstructures produced by this process have wide applications in semiconductor electronics, energy, healthcare, biomedical, aerospace, soft robotics, and automotive industries.

2019.11 Dr. Wang and collaborator Dr. Yu Yao are supported by DOE to develop a polarimetric imaging system to attach to drones and deployed to evaluate the performance of concentrating solar-thermal power (CSP) collector systems.(
Measuring polarization has the potential to provide much richer information of objects than conventional optical imagers, which measure only intensity and color. The imaging systems will be small enough to attach to drones and be deployed to evaluate the performance of CSP collector systems. They can also be attached to CSP plant power towers. Autonomous imaging will reveal damage and soiling on collector mirrors and reduce errors in mirror alignment, resulting in improved efficiency.

2019.02 Dr. Wang is awarded the NSF CAREER award to investigate a new strategy towards early-stage cancer diagnostics using liquid biopsy on an integrated optofluidic chip. (
The research objective of this CAREER proposal is to validate the hypothesis that an integrated and multiplexed optofluidic platform can accurately detect exosomal miRNAs. In pursuit of this goal, a nanofluidic chip (ExoMiRChip) will be designed to functionally integrate label-free exosome purification, on-chip exosomal miRNA extraction, and plasmonic miRNA sensing. Theories and experiments will be combined to address fundamental challenges in achieving high-resolution and high-throughput exosome nanoparticle sorting, high-sensitivity and high-specificity miRNA detection, and multi-functional integration of nanofluidic systems.

2018.08 Dr. Wang and collaborator Dr. Yu Yao are supported by NSF to develop an ultracompact on-chip integrated metasurface polarimetric imager.(
It is no exaggeration to say that the development of imaging sensors has made profound impact on our life, from a smartphone camera to the most advanced medical imaging equipment, and even to space exploration. Detecting light polarization has been proven to be essential for various applications such as biomedical diagnostics, remote sensing, target detection and astronomy. Yet, despite the fact that the sensitivity, speed, pixel density and color range of image sensors have been continuously improved, the capability of full-polarization imaging, hasn’t been realized on monolithically integrated sensors. This project is to develop a chip-integrated imaging sensor array, or in another word, polarimetric imaging array, to detect not only light intensity and color but also the complete polarization state of light. Such a compact system can be further incorporated into many portable systems for clinic diagnostics, real time environmental monitoring network, or a smartphone polarimeter for field study and research. By integrating research and education, the project is aimed to inspire and cultivate the next-generation of scientists and engineers in nanophotonics and nanotechnology to address grand challenges in health, security, environmental issues and space exploration.

2018.07 Dr. Wang and collaborators Dr. Sefaattin Tongay and Dr. Yu Yao are supported by NSF to explore new strategies to integrate quantum emitter arrays in 2D artificial superlattices with nanophotonic structures towards room temperature quantum logic operations. (
Two-dimensional (2D) crystals are a new class of materials that measure only a few nanometers in thickness. Recent studies have shown that these materials offer unique advantages over other known materials, and that they hold the potential to make a large impact in new-generation electronics, energy conversion, and storage applications. When these 2D crystals are stacked onto each other they form a material known as a 2D Moire superlattice, which possesses an unusual physical properties that may enable quantum computation. Such materials could revolutionize current information technologies. This research aims to reach a fundamental understanding of the optical behavior of 2D Moire superlattices using advanced optical measurement techniques, as well as develop state-of-the-art fabrication techniques to create nanoscale devices for manipulation of quantum information. Particularly, this research explores the quantum optics of Moire quantum emitters (Moire-QEs) as single-photon emitters and their integration with Fano-dielectric metacavities, allowing manipulation of coherent states in quantum logic operations. The research activities have significant impact on training of next-generation researchers. Doctoral and master students, as well as undergraduates conduct all the necessary experiments, participating in hands-on research activities.

2017.07 Dr. Wang is supported by NSF to collaborate with researchers at Iowa State University to design a silicon based nano-opto-fluidic chip for rapid exosome profiling. (

Liquid biopsy has significant advantages over traditional tumor biopsies, because it is minimally invasive and uses biofluids, such as blood and urine, to diagnose cancer and other diseases in their early stages. Exosomes, which are actively secreted from cancer cells, carry molecular constituents of their originating cells. The goal of this project is to develop a new capability to rapidly screen and profile exosomes based on both molecular and size characteristics. This research will lead to a transformative change in exosome analysis by integrating two state-of-the-art technologies on a single silicon chip. In addition, this research will be integrated with education through adding new lab modules to existing undergraduate biomedical engineering minor program curriculum, recruiting female students, and providing summer internship opportunities to African-American students to participate in the project at Iowa State University, and developing a new undergraduate-level course related to nanobiotechnology at Arizona State University.

2016.6 Dr. Wang’s paper entitled “Nanoscale Lateral Displacement Arrays for Separation of Exosomes and Colloids Down to 20nm” has been accepted to publication on Nature Nanotechnology. In this work, we study exosomes to demonstrate the capability of a new technology, termed nanoDLD arrays, in separating and collecting bio-colloid for “liquid biopsies”. Exosomes are important biomarkers for detecting cancers and other diseases, because of their accessibility and molecular cargo correlating with the state of their cell source. We present nanoDLD technology to analyze, sort and collect exosomes based on their sizes (average 59 nm, ranging 20-140 nm), a necessary precursor for single-particle exosome analysis. This work was accomplished in collaboration with IBM T.J. Watson research center and Princeton University.
