Amfani da Spectroscopy a fannin Biomedicine
NMR (Maganin Magnetic Resonance) Spectroscopy
NMR spectroscopy yana da fa'ida sosai a fannin ilimin halittu. Ana amfani da shi don tantance tsarin kwayoyin halitta da na halittu dalla-dalla. A cikin binciken ilimin halittu, NMR yana taimaka wa masu bincike su fahimci yanayin kwayoyin halitta masu girma uku kamar sunadarai, nucleic acid, da carbohydrates. Wannan yana da mahimmanci ga ci gaban magunguna, saboda halaye da ayyukan kwayoyin halitta galibi sun dogara ne akan yanayin su.
A fannin binciken lafiya, ana amfani da hoton Magnetic Resonance Imaging (MRI), wanda ya dogara ne akan ƙa'idar NMR, don samar da cikakkun hotuna na tsarin jikin mutum. Wannan dabarar tana da matuƙar amfani wajen gano ƙari, lalacewar nama, da sauran cututtuka ba tare da buƙatar hanyoyin da za a bi ba.
Mass Spectroscopy
Gwajin gwaje-gwajen kitse (mass spectrometry, MS) wata dabara ce da ake amfani da ita don gano sinadaran da ke cikin samfurin bisa ga rabon mass-to-charge (m/z) na ions ɗinsa. A cikin maganin biomedicine, ana amfani da MS don nazarin proteomic, metabolomic, da lipidomic. Wannan dabarar tana ba masu bincike damar yin nazarin furotin, metabolites, da lipids a adadi da inganci, wanda yake da mahimmanci don fahimtar hanyoyin cututtuka da haɓaka masu neman magani.
An kuma yi amfani da MS a cikin binciken asibiti, misali wajen gano alamun cutar. Ta hanyar gano alamun cutar, ana iya gano cututtuka kamar ciwon daji a matakin farko, wanda hakan ke ba da damar yin gaggawa da kuma ingantaccen magani.

Ana amfani da na'urar UV-Vis spectroscopy don nazarin samfuran da ke shan hasken ultraviolet ko haske da ake iya gani. Wannan dabarar tana da sauƙi kuma mai sauri, wanda hakan ya sa ake amfani da ita akai-akai a dakunan gwaje-gwaje na asibiti don nazarin adadi na ƙwayoyin halitta kamar furotin, nucleotides, da enzymes.
Misali, a lokacin gano cutar hanta, ana iya auna yawan bilirubin a cikin jini ta amfani da na'urar UV-Vis spectroscopy. Ana kuma amfani da wannan kayan aikin akai-akai a cikin nazarin enzymology don auna ayyukan enzymology ta hanyar bin diddigin canje-canje a cikin shaye-shaye sakamakon halayen enzymatic.
Infrared Spectroscopy (IR)
Ana yin gwajin infrared (IR) spectroscopy ne bisa ga shan hasken infrared ta hanyar amfani da samfurin ƙwayoyin halitta. Kowace ƙwayar halitta tana da tsarin sha na infrared na musamman, wanda za'a iya amfani da shi don gano ƙwayoyin halitta da kuma tantance su. A cikin maganin halittu, ana amfani da IR don nazarin tsarin furotin na biyu, hulɗar ligand-receptor, da canje-canje a cikin tsarin nazarin cututtuka.
Fourier Transform Infrared Spectroscopy (FTIR) wani nau'in IR ne da ake yawan amfani da shi. FTIR yana ba da ƙarin cikakkun bayanai game da abubuwan da ke cikin cakuda. Wannan yana da amfani musamman a cikin histology da pathology, inda zai iya taimakawa wajen gano da rarraba kyallen da ke da ciwon daji.

A cikin maganin halittu, ana amfani da Raman spectroscopy akai-akai a binciken cutar kansa don gano alamun halittu da sunadaran da ke da alaƙa da ƙari.
Ana kuma amfani da Raman spectroscopy don gano cututtuka marasa haɗari. Misali, ana iya amfani da Raman sprinting don yin nazarin sinadaran da ke cikin kyallen takarda ko ruwan jiki kai tsaye ba tare da buƙatar shirya samfuri mai rikitarwa ba. Wannan yana da babban damar yin amfani da shi a cikin jiki, kamar gano cutar kansar fata ba tare da buƙatar yin biopsy ba.
Kalubale da kuma Damar Spectroscopy a fannin Magungunan Halittu
Kalubale
Duk da cewa na'urar duba bayanai (spectroscopy) tana ba da fa'idodi da yawa, tana kuma fuskantar ƙalubale da dama. Ɗaya daga cikin irin wannan ƙalubalen shine sarkakiyar bayanai.
