Problems solved by technology

However, no technique exists that readily provides visual differentiation between different neurons
Surgeons have difficulty seeing nerve tissue during surgery, and improperly cutting or damaging nerves during surgery can have lifelong adverse effects on patients

[0170] Conjugation of peptides to the C' point for visual differentiation of neural tissue during surgical procedures

[0171] The peptide used in this example is 17AANP41, which includes the core sequence NTQTLAKAPEHT (SEQ ID NO: 3). However, this example is not limited to the 17AA neural binding peptides provided. For example, other peptides (e.g., anti-parathyroid hormone (PTH) and GATA antibodies (e.g., GATA1 antibodies, such as GATA2 antibodies, such as GATA3 antibodies, such as GATA4 antibodies, such as GATA5 antibodies), such as ChAT , such as anti-CGRP), as described herein.

[0172] Choline acetyltransferase (ChAT), an enzyme that catalyzes the formation of acetylcholine, is overexpressed in motor nerves such as the facial nerve. Choline acetyltransferase therefore serves as an attractive target for motor neurons.

[0173] Choline acetyltransferase

[0174] Commercially available anti-ChAT antibody fragments (eg, scFv or Fab) were used as ligands for generating C'...

Abstract

Described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C' dots) to graphically differentiate specific nerves (e.g., sensory nerves vs. motor nerves) for nerve transplants and other surgeries. Also described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C' dots) to graphically differentiate between different types of lymphnodes and / or lymphatic pathways, e.g., to safely and effectively perform vascularized lymph node transplantation in the treatment of lymphedema. Also described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C' dots) to graphically differentiate parathyroid tissue.
