Amalgam Rx, Gets FDAApproval for Insulin

Titration App

AmalgamRx, a newly unstealthed company founded by

WellDoc founders Ryan Sysko and Dr. Suzanne Clough,

has received FDA clearance for iSage, an insulin titration

algorithm. iSage is a prescription-only patient-facing iOS

and Android app that works in conjunction with a web

portal used by the doctor.The doctor sets target levels

for insulin based on the patient’s glucose levels.Then the

algorithm takes over. Patients can enter their blood glu-

cose levels and iSage will change their insulin dosing levels based on the doctor’s

plan and the entered values.

Biological sensor can detect glucose levels in saliva

more accurately and cost-efficiently than blood test

Dr Yan Feng and his research team at The Hong Kong Polytechnic University

(PolyU) have developed a highly sensitive, accurate, flexible and affordable biologi-

cal sensor that can detect glucose levels in saliva.

The device is based on an organic electrochemical transistor (OECT), a highly

sensitive and easy-to-fabricate platform for biosensors. The OECT platform uses

a glucose oxidase enzyme, which is only sensitive to glucose.The team then coat-

ed the enzyme with two types of polymer layers to prevent interference from

other substances in saliva, thereby increasing both the selectivity and sensitivity

of the device. The researchers say the

new biosensor is nearly 1,000 times

more sensitive than the conventional

blood glucose testing method.
