Multidimensionally photopatterned substrate on the basis of monosaccharide derivatives, their oligomers and their polymers and a method of production thereof solves the lack of environmentally friendly photoresist compositions, and further the lack of 3-D structuring and the use of a sugar/polysaccharide derivative bearing at least two acid labile groups, the use of hydroxyalkane derivatives as such, which limits the applicability above referenced technical problem by use of silylated sugar/polysaccharide derivatives, further 3-D structuring, and use of enzymes to obtain positive and negative resists. The invention is characterized by 2- and 3-dimensionally patterned substrates composed of a photoresist composition on the basis of mono, di-, oligo and polysaccharide derivatives which bear only one type of acid labile group and a photoacid generator (hereinafter PAG) which generates an acid upon exposure to electromagnetic waves and/or charged particle beams, and/or a 2-photon sensitive PAG
