<Abstract>
An optical tweezer technique using nanotextured Si (black-Si) can efficiently trap polymer chains. By increasing the laser intensity, the local concentration of perylene-labelled water-soluble polymer chains increased inside the trapping potential. Accordingly, the excimer fluorescence of perylene increased while the monomer fluorescence decreased. Based on the behaviour, we can control the fluorescence colour; blue, green, yellow-green, yellow, and orange.
