Abstract
The year 2004 represents a milestone for the biosensor research community: in this year, over 1000 articles were published describing experiments performed using commercially available systems. The 1038 papers we found represent a ∼10% increase over the past year and demonstrate that the implementation of biosensors continues to expand at a healthy pace. We evaluated the data presented in each paper and compiled a ‘top 10’ list. These 10 articles, which we recommend every biosensor user reads, describe well‐performed kinetic, equilibrium and qualitative/screening studies, provide comparisons between binding parameters obtained from different biosensor users, as well as from biosensor‐ and solution‐based interaction analyses, and summarize the cutting‐edge applications of the technology. We also re‐iterate some of the experimental pitfalls that lead to sub‐optimal data and over‐interpreted results. We are hopeful that the biosensor community, by applying the hints we outline, will obtain data on a par with that presented in the 10 spotlighted articles. This will ensure that the scientific community at large can be confident in the data we report from optical biosensors. Copyright © 2005 John Wiley & Sons, Ltd.
