Enzymatic detachment of cells might damage important features of cells and could affect subsequent function of cells in various applications. Therefore, non-enzymatic cell detachment using thermosensitive polymer matrix is necessary for maintaining cell quality after harvesting. In this study, we synthesized thermosensitive PNIPAm-co-AAc-b-PS and PNIPAm-co-AAm-b-PS copolymers and LCST was tuned near to body temperature. Then, polymer solutions (5% w/v, 10% w/v, and 20% w/v) were spin coated to prepare films for cell adhesion and thermal-induced cell detachment. The apha-step analysis and SEM image of the films suggested that the thickness of the films depends on the molecular weight and concentration which ranged from 206 nm to 1330 nm for PNIPAm-co-AAc-b-PS and 97.5 nm to 497 nm for PNIPAm-co-AAm-b-PS. The contact angles of the films verified that the polymer surface was moderately hydrophilic at 37°C. From cell attachment and detachment studies, RAW264.7 cells, were convincingly proliferated on the films to a confluent of >80 % within 48 days. However, relatively more cells were grown on PNIPAm-co-AAm-b-PS (5%w/v) films and thermal-induced cell detachment was more abundant in this formulation. As a result, commercial cytodex 3 microcarrier was coated with PNIPAm-co-AAm-b-PS (5%w/v) and interestingly enhanced cell detachment with preserved potential of recovery was observed at low temperature during 3D culturing. Thus, surface modification of microcarriers with PNIPAm-co-AAm-b-PS could be vital strategy for non-enzymatic cell dissociation and able to achieve adequate number of cells with maximum cell viability, and functionality for various cell-based applications.
