Ultrasensitive Materials for Electrochemical Biosensor Labels

open access: yesSensors, 2020
Since the fabrication of the first electrochemical biosensor by Leland C. Clark in 1956, various labeled and label-free sensors have been reported for the detection of biomolecules.

Label Preference Schemes in GMPLS Controlled Networks [PDF]

open access: yes, 2006
The GMPLS assumption that all available labels are equal is reasonable in electronic networks but not always true in WDM optical networks where labels correspond to physical wavelengths.

Effects of crosstalk in WDM optical label switching networks due to wavelength switching of a tunable laser [PDF]

open access: yes, 2006
rosstalk caused by switching events in fast tunable lasers in an optical label switching (OLS) system is investigated for the first time. A wavelength-division-multiplexed OLS system based on subcarrier multiplexed labels is presented which employs a 40 ...

Toward Photon-Efficient Key Distribution over Optical Channels [PDF]

open access: yes, 2014
This work considers the distribution of a secret key over an optical (bosonic) channel in the regime of high photon efficiency, i.e., when the number of secret key bits generated per detected photon is high.

Colourful 3D anti-counterfeiting label using nanoscale additive manufacturing

open access: yesVirtual and Physical Prototyping, 2023
Microprinting is changing anti-counterfeit technology by producing complex micro-/nano-scale labels to increase the security level. However, the current microprinted anti-counterfeiting labels only contain 2D features, thought of as single coding (e.g ...

Rational design and synthesis of SERS labels [PDF]

open access: yes, 2013
SERS labels are a new class of nanotags for optical detection based on Raman scattering. Central advantages include their spectral multiplexing capacity due to the small line width of vibrational Raman bands, quantification based on spectral intensities,
