Ka taea te whakarōpū i ngā huaketo i runga anō i te pūtau kaihautū e pāngia ana e rātau: huaketo kararehe, huaketo tipu, huaketo pūngāwerewere, me ngā huaketo bacteriophage (huaketo e pāngia ana e te huaketo, kei roto nei ngā huaketo tino matatini). Ka whakamahia e tētahi atu whakarōpūtanga te āhua āhuahanga o tō rātau capsid (he maha he he hēlika, he icosahedron) te hanganga rānei o te huaketo (hei tauira, te aroaro, te kore rānei o te āputa lipid). Ka rerekē te rahi o ngā huaketo mai i te 30 nm ki te 450 nm, ko te tikanga kāore e taea te kite i te nuinga o rātau mā te āhuahanga mārama. Kua rangahautia te āhua me te hanganga o ngā huaketo mā te āhuahanga hiko, te āhuahanga NMR, me te whakaahua tioata X. Pātai: Me pēhea te whakarōpū i ngā huaketo?
