Selective electroless nickel plating of particle arrays on polyelectrolyte multilayer was investigated for the potential applications in sensors, optoelectronics, and biochips.96 This process is based on the preparation of functional colloidal arrays on surfaces. In the next step metal deposition is carried out on the surfaces of the patterned particles secured on the substrate. Samples of colloidal arrays on patterned polyelectrolyte templates are first pretreated with a Pd(II)-based catalyst. After rinsing with deionized water and drying, samples were plated with nickel using dimethylamine borane (DMAB) as a reducing agent. Based on the results of this work,96 it was shown that the selective electroless nickel deposition on 3D patterned surfaces can be successful. 

Multiscale ordering of functional colloidal nanoparticles is a powerful technique for the creation of macroscopic devices. This can be performed via selective polymerization, self-assembly processes, or through controlled molecular recognition processes (Fig. 4). Further assembly between NBB is addressed following three main strategies, namely, electrostatic coupling, covalent, or self-assembly-based noncovalent binding.

A study of interaction between SQDs and biological structures has shown binding of peptide-functionalized colloidal SQDs to transmembrane proteins in the bilipid membranes of cells [3]. In this work SQDs are bound to CGGGRGDS peptide through the thiol link between the cysteine (C) and SQD. 

Chemically prepared CdS SQDs were functionalized with peptides composed of CGGGRGDS, CGGGRVDS, CGGIKVAV, and CGGGLDV. The peptide-functionalized colloidal CdS nanocrystals were synthesized using techniques of colloidal chemistry [4]. In particular, a 5 mM solution of CdCl2 (36.6 mg of CdCl2 in 40 mL of H2O) was titrated with mercaptoacetic acid until pH=2 was...

In recent years, asymmetric nanosihca have not been widely used, most likely due to a lack of convenient ways in which they can be manipulated. Nonetheless, these materials should have an effective application potential in asymmetric catalysis, although their sizes (e.g. nanocoils) must be tightly controlled. The details of asymmetric colloids of many compositions have been discussed. For example, Correa-Duarte et al. described the creation of asymmetric functional colloids through selective hemisphere modification [54], a method which could easily be expanded for the modification of silica nanoparticles and asymmetric nanosihca.
