NTU Singapore researchers develop pollen-based ‘paper’

In Singapore, scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a pollen-based ‘paper’ that, after being printed on, can be ‘erased’ and reused multiple times without any damage to the paper.

In a research paper published online in Advanced Materials on 5 April, the NTU Singapore scientists demonstrated how high-resolution color images could be printed on the non-allergenic pollen paper with a laser printer, and then ‘unprinted’ – by completely removing the toner without damaging the paper – with an alkaline solution. They demonstrated that this process could be repeated up to at least eight times.
