Claims9
A method for the manufacture of a free standing segmented nanoparticle comprising a plurality of materials, the method comprising:
- a. providing a template comprising a plurality of pores by the method comprising the steps:
- i) providing a resist-coated substrate;
- ii) exposing a pattern on said resist-coated substrate using a photolithographic technique;
- iii) developing said pattern;
- iv) etching said pattern to form a plurality of pores;
- b. causing deposition of a first material into said pores;
- c. causing deposition of a second material into said pores;
- and
- d. releasing said segmented nanoparticles from said template, wherein a segment bisects the length of the particle.
A method for the manufacture of a free standing segmented nanoparticle comprising a plurality of materials, the method comprising:
