ABSTRACT

In this talk, I will present our Laboratory work on highly-quantitative plasmonic sensing based on Surface Enhanced Raman Spectroscopy (SERS). I will first describe our nano-imprinted SERS substrate architecture and performance. Then I will show how inkjet dispensing can be used in conjunction with SERS to encode each sensor with a calibration pattern of microdroplets (~30 pico-liters), with the aim of locally calibrating sensor performance. This way, we demonstrate that Measurement Uncertainty of the SERS signal can be reduced below 2%, which to our knowledge, is a new record for plasmonic sensing platform. Furthermore, the use of inkjet dispensing in combination with Raman mapping improves assay throughput (100-fold) and reduces sample volume consumption (105-fold) in an automated and reproducible fashion. Since this approach overcomes important practical hurdles, we believe that this work reignites interest in the potential commercialization of plasmonic-based chemical sensors.

Recent paper for reference:  A Generalizable Single-Chip Calibration Method for Highly Quantitative SERS via Inkjet Dispense.

drfaustoheadshot

Dr. Fausto D’Apuzzo is Optical Scientist at HP Labs, working on the Life Science team. His research interests are in optics systems, plasmonics and metamaterials for bio-sensing, with a focus on Surface Enhanced Raman Spectroscopy (SERS). He started investigating plasmonic systems since his master (2011) and PhD at the University of Rome “Sapienza”, before holding a postdoc position at L. Berkeley National Labs (LBNL) studying 2D plasmonic systems with Synchrotron Nano-Spectroscopy. He interned as an Optical Engineer at ACAMP (Alberta, Canada) before joining HP Labs (2018-present) where he is developing plasmonic sensing systems for quantitative chemical analysis.

SFBA Nano Wins Outstanding Chapter Award

Thursday, February 6th, 2014

Gold Ribbon canstockphoto2647524The IEEE Region 6 2014 Outstanding Chapter Award was just awarded to our own IEEE San Francisco Bay Area Nanotechnology Council Chapter. (The highest award for IEEE Chapters.)

Region 6 has 228 IEEE Chapters in 12 States. It is the largest IEEE Region and holds about 60,000 members out of the IEEE worldwide total of 430,000 members.

Many of our current Executive Committee have been helping to build this Chapter for the last 10 years and we are pleased to share this recognition with our event attendees, many of whom have participated over that entire time and also contributed in many ways.

Thank you and congratulations to us all.

Nick Massetti
2014 Chair, Executive Steering Committee
