M'zaka zaposachedwa, sayansi yamakono yoimiridwa ndi uinjiniya wa majini, uinjiniya wama cell, uinjiniya wa ma enzyme ndi uinjiniya wowotchera yakula mwachangu, ndipo ikukhudza kwambiri ndikusintha kapangidwe ka anthu ndi moyo wawo. Zomwe zimatchedwa biotechnology zimatanthauza "ukadaulo wogwiritsa ntchito zamoyo (kapena zamoyo) kukonza zinthu, zomera ndi nyama, kapena kulima tizilombo toyambitsa matenda pazifukwa zapadera". Bioengineering ndi mawu ambiri a biotechnology, omwe amatanthauza kuphatikiza kwa Biochemistry, molecular biology, microbiology, genetics ndi biochemical engineering kuti asinthe kapena kupanganso ma genetic a maselo opangidwa, kulima mitundu yatsopano, kugwiritsa ntchito njira zomwe zilipo pamakampani. , ndi kupanga zinthu zamakampani pogwiritsa ntchito biochemical process. Mwachidule, ndi njira yopanga mafakitale a zamoyo, machitidwe a moyo kapena njira zamoyo. Bioengineering ikuphatikizapo genetic engineering, cell engineering, enzyme engineering, fermentation engineering, bioelectronic engineering, bioreactor, sterilization technology ndi protein engineering yomwe ikubwera.
