'''Biophotonics''' employs tools from the field of photonics to the study of [[biology]]. Biophotonics mainly focuses on improving medical diagnostic abilities (for example for cancer or infectious diseases)<ref>{{Cite journal|last1=Lorenz|first1=Björn|last2=Wichmann|first2=Christina|last3=Stöckel|first3=Stephan|last4=Rösch|first4=Petra|last5=Popp|first5=Jürgen|date=May 2017|title=Cultivation-Free Raman Spectroscopic Investigations of Bacteria|journal=Trends in Microbiology|volume=25|issue=5|pages=413–424|doi=10.1016/j.tim.2017.01.002|issn=1878-4380|pmid=28188076}}</ref> but can also be used for environmental or other applications.<ref>{{Cite journal|last1=Wichmann|first1=Christina|last2=Chhallani|first2=Mehul|last3=Bocklitz|first3=Thomas|last4=Rösch|first4=Petra|last5=Popp|first5=Jürgen|date=5 November 2019|title=Simulation of Transportation and Storage and Their Influence on Raman Spectra of Bacteria|journal=Analytical Chemistry|volume=91|issue=21|pages=13688–13694|doi=10.1021/acs.analchem.9b02932|issn=1520-6882|pmid=31592643|s2cid=203924741 }}</ref><ref>{{Cite journal|last1=Taubert|first1=Martin|last2=Stöckel|first2=Stephan|last3=Geesink|first3=Patricia|last4=Girnus|first4=Sophie|last5=Jehmlich|first5=Nico|last6=von Bergen|first6=Martin|last7=Rösch|first7=Petra|last8=Popp|first8=Jürgen|last9=Küsel|first9=Kirsten|date=January 2018|title=Tracking active groundwater microbes with D2 O labelling to understand their ecosystem function|journal=Environmental Microbiology|volume=20|issue=1|pages=369–384|doi=10.1111/1462-2920.14010|issn=1462-2920|pmid=29194923|bibcode=2018EnvMi..20..369T |s2cid=25510308}}</ref> The main advantages of this approach are speed of analysis, [[non-invasive]] diagnostics, and the ability to work [[in-situ]].
