text: hole pattern [3, 13], and the stability of the individual dewetting fronts [17–19]. We note in 
  
  passing, that descriptions of dewetting patterns may also be found in historic papers, particularly 
  
  for the dewetting of a liquid ﬁlm on a liquid substrate. Tomlinson [20, footnote 18 on p. 40] 
  
  considered turpentine on water and Marangoni [21, p. 352f] oil on water. 
  
  More recently, interest has turned to the dewetting processes of solutions and suspensions. How- 
  
  ever, these systems have not yet been investigated in any great depth. Such systems are compli- 
  
  cated because their behaviour is determined by the interplay between the various solute (or colloid) 
  
  and solvent transport processes. Furthermore, the solvents that are used often evaporate, i.e., one 
  
  has to distinguish between ‘normal’ convective dewetting and evaporative dewetting. A number 
  
  of experiments have been performed employing (colloidal) solutions of polymers [22–25], macro- 
  
  molecules like collagen and DNA [26–31] and nanoparticles [32–40]. The latter are sometimes 
  
  referred to as ‘nanoﬂuids’. The initial focus of much of the research in the ﬁeld has been on
