New publications keep coming from the ESRs, this time with an interesting review about micro barcodes. ESR4 Abdur Anwar, co-authored a paper entitled "Microcavity- and Microlaser-Based Optical Barcoding: A Review of Encoding Techniques and Application" within ACS Photnics.
The authors explain microlaser-based optical barcoding over traditional techniques. Microcavity- and microlaser-based barcodes are a very powerful tool which holds great promise. However, it is only in its infancy. By developing new kinds of microcavities as well as optical systems for their detection, they could become both a tool in research as well as useful for numerous applications i.e., product labelling and cell tracking.
