Nanoco Group (LSE: NANO) develops and manufactures fluorescent semiconductor nanoparticles for use in lighting, displays and solar panels. The market for these products is developing "more slowly than anticipated", the firm said recently, which has led to disappointing results. It now plans to raise £8.6m in equity, to allow it to retain its manufacturing facility at Runcorn. The share price has slid by more than half in the last year.
