Boenjineri ba liphatsa tsa lefutso ke motheo oa bioengineering ea sejoale-joale. Boenjiniere ba liphatsa tsa lefutso (kapa boenjiniere ba liphatsa tsa lefutso, theknoloji ea ho kopanya liphatsa tsa lefutso) ke ho khaola le ho kopanya liphatsa tsa lefutso tsa mefuta e fapaneng ea vitro, ho li hokahanya le DNA ea li-vectors (plasmids, phages, virus), ebe li fetisetsa ho likokoana-hloko kapa lisele bakeng sa cloning, e le hore liphatsa tsa lefutso tse fetisitsoeng li ka hlahisoa liseleng kapa likokoana-hloko ho hlahisa liprotheine tse hlokahalang. Ho feta 60% ea likatleho tsa biotechnology e tsepamisitsoe indastering ea meriana ho hlahisa litlhare tse ncha tse ikhethang kapa ho ntlafatsa meriana ea setso, e leng se lebisitseng liphetohong tse kholo indastering ea meriana le nts'etsopele e potlakileng ea biopharmaceuticals. Biopharmaceutical ke mokhoa oa ho sebelisa theknoloji ea bioengineering lefapheng la tlhahiso ea lithethefatsi, eo bohlokoa ka ho fetisisa ho eona e leng boenjiniere ba liphatsa tsa lefutso. Ke ho khaola, ho kenya, ho hokahanya le ho kopanya DNA hape ka ho sebelisa theknoloji ea cloning le theknoloji ea setso sa lisele, e le ho fumana lihlahisoa tsa biomedical. Lithethefatsi tsa likokoana-hloko ke litokisetso tse entsoeng ka biologically tse lokiselitsoeng ka likokoana-hloko, likokoana-hloko, chefo ea liphoofolo le lisele tsa likokoana-hloko e le lisebelisoa tsa ho qala, ho sebelisa mekhoa ea likokoana-hloko kapa karohano le theknoloji ea ho hloekisa, le ho sebelisa theknoloji ea baeloji le ea tlhahlobo ho laola boleng ba lihlahisoa tse bohareng le lihlahisoa tse felileng, ho kenyelletsa le liente, chefo, toxoids, serum, lihlahisoa tsa mali, litokisetso tsa ho itšireletsa mafung, li-cytokine, li-antigen Li-antibodies tsa Monoclonal le lihlahisoa tsa boenjiniere ba liphatsa tsa lefutso (lihlahisoa tsa DNA recombination, in vitro diagnostic reagents), joalo-joalo. ka mekhahlelo e meraro ho latela ts'ebeliso ea bona e fapaneng: meriana ea boenjineri ba liphatsa tsa lefutso, liente tsa baeloji le li-reagents tsa tlhahlobo ea baeloji.
