Label free, quantitative single-cell fate tracking of time-lapse movies
MethodsX, 2019 Historically, the ability to perform multi-day time-lapse imaging of adherent cells required expensive and specialized microscopy equipment. As byproduct of this cost, many labs would synchronize cells using inhibitors such as hydroxyurea and thymidine ...

Label-Free Ultrasensitive Memristive Aptasensor [PDF]
Nano Letters, 2016 We present the very first worldwide ever-reported electrochemical biosensor based on a memristive effect and DNA aptamers. This novel device is developed to propose a completely new approach in cancer diagnostics. In this study, an affinity-based technique is presented for the detection of the prostate specific antigen (PSA) using DNA aptamers.

, 2023 Label-free quantification is an important mass spectrometry method that requires no specific sample labelingInstead, it utilized MS/MS generated signals of specific peptides for comparison to define protein expression modifications between samples. Two alternative label-free quantification strategies are frequently used.
