Editing Biosensor (section)

===Epigenetics===
It has been proposed that properly optimized integrated optical resonators can be exploited for detecting epigenetic modifications (e.g. DNA methylation, histone post-translational modifications) in body fluids from patients affected by cancer or other diseases.<ref>{{cite journal | last1 = Donzella | first1 = V | last2 = Crea | first2 = F | date = June 2011 | title = Optical biosensors to analyze novel biomarkers in oncology | journal = J Biophotonics | volume = 4 | issue = 6| pages = 442–52 | doi = 10.1002/jbio.201000123 | pmid = 21567973 | s2cid = 5190250 }}</ref> Photonic biosensors with ultra-sensitivity are nowadays being developed at a research level to easily detect cancerous cells within the patient's urine.<ref>{{cite journal | last1 = Vollmer| first1 = F | last2 = Yang | first2 = Lang | date = October 2012 | title = Label-free detection with high-Q microcavities: a review of biosensing mechanisms for integrated devices | url = http://www.degruyter.com/dg/viewarticle.fullcontentlink:pdfeventlink/$002fj$002fnanoph.2012.1.issue-3-4$002fnanoph-2012-0021$002fnanoph-2012-0021.xml?t:ac=j$002fnanoph.2012.1.issue-3-4$002fnanoph-2012-0021$002fnanoph-2012-0021.xml | journal = Nanophotonics | volume = 1 | issue = 3–4| pages = 267–291 | doi = 10.1515/nanoph-2012-0021 | pmid = 26918228 |bibcode = 2012Nanop...1..267V | pmc = 4764104 }}</ref> Different research projects aim to develop new portable devices that use cheap, environmentally friendly, disposable cartridges that require only simple handling with no need of further processing, washing, or manipulation by expert technicians.<ref>{{cite web|url=http://www.glam-project.eu|title=Home - GLAM Project - Glass-Laser Multiplexed Biosensor|website=GLAM Project - Glass-Laser Multiplexed Biosensor}}</ref>
