Methods for selective attachment include the use of optical attachment using a patterned exposure to assist in the creation of receptor bonding to pre-selected regions of the one or more chips. Blocking agents are attached to regions where blocking the receptor attachment is beneficial. Biased conducting regions may also affect selective attachment. Such controlled blocking may be accomplished using optical patterning exposure with optical assisted bonding of the blocking molecule or lift off processes. Patterned exposure for either attachment assists or liftoff processes employs photo masks. Conducting regions outside of the active sensor gate region are biased, affecting biochemical binding or non binding, and shielding of the semiconductor region outside of the active biosensor region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Biosensor chip sensor protection methods","description":"Receptors are selectively attached by introducing blocking materials in the areas outside the active sensor surface area, and/or selectively attaching the bio receptors to one or more active sensor su","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8536661","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
