Bioanalytical Sensors 2016 Gordon Research Conference

Heather recently attended the Bioanlaytical Sensors Gordon Research Seminar and Conference in Newport, Rhode Island.  Her poster, Multiplexed Cytokine-Chemokine Profiling Using Microring Resonator Arrays to Diagnose Latent Tuberculosis Infection, was awarded the Royal Society of Chemistry Analyst Top Poster Prize (of 5).  Consequently, Heather presented a short talk in the Young Investigator Late Breaking Topic session to close out the GRC.

Biosensors 2016 Conference

Enrique recently attended the Biosensors 2016 Congress in Gothenburg, Sweden. His talk, Multiplexed detection of clinically-relevant biomarker panels using a silicon photonic biosensing platform: Application to Sepsis and Tuberculosis diagnostics, reported on the lab's recent efforts to transform the microring resonator array technology into a robust in vitro diagnostic platform.

Congrats to Quique on a successful meeting and presentation!

Nanoporous Gold Membranes as Robust Constructs for Selectively Tunable Chemical Transport

Abstract

Nanopores are promising structures for small volume separations, but often require complex topdown fabrication and are not easily (re)configurable to allow for dynamically tuned separations. Herein we report the first use of nanoporous gold (NPG) membranes as tunable, charge-based separation elements. NPG is fabricated into a robust network of interconnecting pores via simple solution de-alloying. We demonstrate that control over the selective permeation of small molecule analytes can be controlled via three different methods: 1) anion adsorption at the Au surface; 2) pH-tuning of self-assembled monolayer (SAM) charge; and 3) electrochemical oxidation of a redox-active SAM. This simple and versatile membrane system is promising as a dynamically-tunable element for small volume separations.

SACNAS 2015 National Conference

Ryan, Alex, and Ruth recently attended the SACNAS National Conference held in Washington D.C.  SACNAS (the Society for the Advancement of Chicanos and Native Americans in Science) is an organization dedicated to the success of Chican@, Hispanic, Latin@, and Native American scientists to attain positions of leadership in government, industry, and academia.  Alex is president of the UIUC chapter, while Ryan is a faculty adviser for the chapter's successful Cena y Ciencias outreach program.  This year, the UIUC chapter won Graduate Chapter of the Year, and four members won individual awards for their research presentations.  Ryan was one of six presenters giving a workshop on how to establish an active outreach program with local elementary schools.
