The additional ligand comprising primary 3-20C alkyl amine(s), secondary 3-20C alkyl amine(s), tertiary 3-20C alkyl amine(s), and bidentate ligand(s) comprising 10-20C alkane which is ( alpha ),( omega ) disubstituted with amine, thiol, alcohol, carboxylic acid, sulfonic acid, or phosphonic acid, is chosen from 1,12-dodecanediamine, 4,9-dioxa-1,12-dodecanediamine, dodecanedioic acid, 1,1-aminoundecanoic acid, 1,1-sulfinoundecanoic acid or decane-1,10-disulfonic acid. The surfactant comprises dodecyl trimethylammonium bromide. The water-miscible solvent comprises ethylene glycol. Fluid (F1) including polymerizable or cross-linkable material is melt. The solid material is solidified glass and/or crystal from melt.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The polymer is elastomeric network, thermoplastic or thermoset. The elastomeric network is crosslinked polydimethylsiloxane. Preferred Process: During preparation of rice-shaped colloidal superparticles, water-soluble ligand comprising Tween 20-SH (RTM: polyoxyethylene (20) sorbitan monooleate) or SH-type polyethylene glycol is injected to aqueous suspension, and obtained colloidal superparticles are isolated from aqueous suspension by centrifugation. During infiltration of rice-shaped colloidal superparticles into microchannels, fluid flow is promoted on surface of substrate by gravity flow during carrying out deposition at an elevated edge of surface which is not plane, and spin casting, rolling or doctor blading. During removal of one portion of liquid, a gas flow counter to the gravity flow is provided. Fluid (F1) is placed on surface of nanorod assembly within microchannels of substrate, fluid is converted into a solid material by polymerization or cross-linking, and solid material is separated from surface of substrate by delamination and dissolving or decomposing the substrate. The nanorod assemblies are imbedded within the solid material. The substrate with nanorods within microchannels is conformed as a cylinder with microchannels situated on outside of cylinder, and cylinder is rolling upon surface (SA1). The nanorod assemblies are transferred to surface (SA1). Preferred Property: The nanorod assembly has length of 50 microns or more. The microchannels have length of 10 microns or more and cross-section smaller than long axes of rice-shaped colloidal superparticles.
