Maintaining the integrity of analytical data over time is a challenge. Years ago, data were recorded on paper that was pasted directly<br />
into a laboratory notebook. The digital age has made maintaining the integrity of data harder. Nowadays, digitized analytical data are<br />
often separated from information about how the sample was collected and prepared for analysis and how the data were acquired. The<br />
data are stored on digital media, while the related information about the data may be written in a paper notebook or stored separately in<br />
other digital files. Sometimes the connection between this “scientific metadata” and the analytical data is lost, rendering the spectrum or<br />
chromatogram useless. We have been working with ASTM Subcommittee E13.15 on Analytical Data to create the Analytical Information<br />
Markup Language or AnIML — a new way to interchange and store spectroscopy and chromatography data based on XML (Extensible<br />
Markup Language). XML is a language for describing what data are by enclosing them in computer-useable tags. Recording the units<br />
associated with the analytical data and metadata is an essential issue for any data representation scheme that must be addressed by all<br />
domain-specific markup languages. As scientific markup languages proliferate, it is very desirable to have a single scheme for handling<br />
units to facilitate moving information between different data domains. At NIST, we have been developing a general markup language just for<br />
units that we call UnitsML. This presentation will describe how UnitsML is used and how it is being incorporated into AnIML.<br />

Smart Automated System for the Assessment of Biosensor’s Performance<br />
The portable, quick, and automatic multi-sensing system for biological agent is regarded necessary as the concern of public. However<br />
current detection techniques cannot be applied to the field since they are based on large instruments or highly skilled manipulation. The<br />
detection system can be developed when electrochemical impedance analysis (EIA) is employed as biosensor’s signal transducer however<br />
the absence of appropriate technique to associate antibody onto biosensor’s surface and the lack of understanding of the electrochemical<br />
dynamics at the interface of biosensor are the bottleneck to develop. We propose the smart automated system for the assessment of<br />
biosensor’s performance, able to accelerate evolution of biosensing technology to be applied for environmental and biological samples<br />
with complex matrix (human clinical samples, foods, and beverages). We’ve succeeded to detect 0.1ng/ml of Staphylococcus aureus<br />
Enterotoxin B (SEB) with new impedimetric bioosensor. To achieve the high sensitivity, aluminum, the module of signal transducer,<br />
was fabricated electrochemically in nano-scale as well as the technique to associate anti-SEB on nano-porous aluminum surface was<br />
developed. The biosensor differentiated SEB and anti-SEB reaction at the specific AC frequency (30-100kHz) in 20min. The dynamics<br />
of multi-analyte and the algorithm to differentiate multiplexed signals are being studied to establish the basis of automated multi-target<br />
biosensor. Developed algorithm will allow the automation of the impedimetric multi-biosensor, the evaluation of individual sensor’s<br />
performance, and the improvement of reliability. LabView based software will allow to perform 4D (electrical amplitude, phase angle,<br />
frequency, and time) chemical screening of target analysts.<br />
